 Subject: 6.5 diesel stalls
Message:
I have a 1995 Chev. pickup (250) with a 6.5 diesel engine with a turbocharger. Several times it just stalled for no apparent reason; the engine just quit, then it restarts with the key with no problem. Otherwise it runs perfect. It seems as though the fuel is shutting off. Is there a generic problem (maybe a service bulletin) that covers this phenomena. There are quite a few things that can interrupt the fuel process and I don't know where to start.

I don't know about the diesels, but my Chevy did this just recently, and it was the ignition. Eventually it just died, on the freeway, ugh, so I would check that out as an option before it happens to you. It was $127.95 for us to get it fixed, but again, this was not a diesel.

Your problem is most likely the PMD/fuel injector pump located under the intake manifold. My 6.5 had the same problem and this was the culprit. Hold your shorts though, its expensive.

I have a 94 6.5 turbo diesel runs great for a time then suddenly just shuts down. The main PCM has been replaced, and the PMD, the APP module on the accellorator has not. The truck has 185000 miles on the pump itself but pump works perfectly until truck just shuts down as if you swithced the ignition off. after some time app. 30 minutes of cooling it restarted, it started,died a few times and ran rough for a couple minutes before it smoothed out and ran perfect. It has done this twice lately. NO codes showed before I replaced the PCM and the PMD. But haven't had them checked since the last two shut downs. SES LIght was on when the engine shut off, but went out as soon as it restarted and smoothed out. Seems as if one of the sensors is getting hot and malfunctioning. Have spent 850 dollars so for on the parts and SCAM Tools. Does any body have a good guess for me.

sounds like you probably need a new PMD or pump driver. Which is located on the pump itself. The rectangular box on the driverside of the pump. Unfortunately it is very diffcult to change out. I recently installed a new one on mine and just remounted it on a metal plate away from the pump. The heat is what gets them. The last one I bought at a chevy dealer was 246.00. GOOD LUCK

My 98 6.5TD would stall as though you turned the key off, but it would start right backup. After several times of this over several months, it just quit. It turned out to be the lift pump. This pump is located below the driver door in the frame. It looks like a filter, but is a lift pump. This pump went bad twice on me. The second pump was under warenty. So keep your receipt!

I just went through the same problems. Started with a PDM, then had the injecter pump checked, changed the optical sensor on top of the pump, check lift pump, replaced lift pump, still missing, and or shutting off going down highway. No codes. WELL, I just fixed mine!!! The computer harness coming out of the firewall, under the coolant tank, had chaffed on the A/C liquid line and the turbo heat sheild. Soldered the wiring, heat shrunk, and install heat barrier covering and now it runs great!!

I had the same stall problem and found out it was the solenoid valve that starts and stops the High Pressure Injector Pump. ( This was after Chevy had hooked me up to the computer for analysis at $180.00 hookup fee ). Mine had 92,000 miles on it.

My 6.5 diesel check engine light is coming on with trouble code 78 (wastegate solenoid). With scanner hooked up and driving wastegate signal is totally lost going from 70% or so to 00% then after a sec. or two back in business to 70% and engine light goes out. Seems like an elec. open to me. Any suggestions appreciated.

Message:
Trouble code 78 was caused in my case by the little electrical connector that plugs into the Wastegate Solenoid. With engine running I could wiggle this connector and the solenoid would start and stop vibrating. It vibrates when its working. When it stops vibrating check engine light comes on. I replaced the Solenoid (GM # 1997227) and electrical connector (GM # 12102747) and no check engine light since. Truck is a 94 Chevy 3/4 ton.

I have a 1993 6.5 diesel that runs just fine when the weather is cool. Once the weather gets up over about 85-90 degrees, the truck will run fine until you shut it off: then it will frequently not restart until the engine cools down. This usually takes about 30 mins to an hour. Then it starts right up and runs fine. This happens frequently, but not every time. Sometimes it will start up when it's still hot.
It runs ok until you shut it off. No hestitation, roughness or smoke. The mechanic says it needs a new pump & driver .... $2,000. Does this sound like it could be the solution? If a new assembly is put it, won't it just overheat too and I'll have the same problem?

It could be the injector pump, BUT, before I'd spend the money, just do a quick check. Put a low pressure fuel gauge on the pump feed line between the fuel filter and the injector pump, and check the lift pump pressure when this no restart happens. If it is below 4 psi it won't work to good... But before you replace the pump, the power for the lift pump, goes through the oil pressure switch, (in- between the fuel filter and injector pump in the valley) Cause that switch can cause a hair pulling, mind bending problem with that lift pump. Took a freind a year to figure that one out... Good Luck

gm has a warranty coverage for the injection pumps on the 6.5s 11 years or 120,000 miles. It covers the electronic injector pumps on the 6.5s. I just bought a 95 and the pump went out just my luck I'm over the mileage limit.

Just put in a new long block on a 96 chevy with the 6.5. Swallowed the #8 piston on old motor with 125,000 miles. Motor runs good, but when pulling our horse trailer the temp rises up to 210 the cooling fan kicks on and everything cools down like its is supposed to. But we have been driving in cool weather and I dont feel the motor should be heating up this much. Im afraid of how hot it mught get when it gets 100 degrees.
I also have a very slight surge at speeds over 70 miles an hour. I have changed the pick-up fuel pump, and we replaced the electronic driver unit on the side of the pump when we built the long block. Any suggestions. Thanks

Figure this one out. I replace the PMD with the remote setup and everything seems fine. Then about three weeks later the truck just dies and wontr restart. The SES light stays on. I disconnect the lifter pump and the truck starts right up. So I reconnect the electrical harness and it now runs fine. No codes ever given?

I also have a 1993 6.5. Mine acted exactly as yours, Mike (runs great in cool wx...). I found out that my lift pump was not working. I changed the pump and the relay and still no go. It turned out to be the oil press sensor. It is a safety feature apparently. No oil press, no fuel. No go.
As long as I parked the truck nose down, it would start. Not a good remedy since I live in the praires. It has been working great since, even in 30oC wx.

that code 88 is your timing for the injection pump is off. my 94 Tahoe had that same code after i replaced the pump so i took it to a guy i knew that was a diesel mech. he said mine was off 3 degree so mark your pump and turn it the thinkness of a dime either way to see if the light goes out. PLUS EVERYONE KNOW THIS CHEVY WARRENTIES THE 6.5 INJECTION PUMP TO 121,000 MILES. i found this out after i had spent the money for a new one.

My 95 silverado missed and balked etc. like many posts. At 97,000 I took it to a dealer and they discovered metal filings in the system and fuel filter. Told me the injector pump had " chewed itsself up " and that this was quite common. They flushed my system, installed new lift pump and injector pump , drained and flushed my tank and it now works great. And get this!! I was told GM was aware of this problem and extended the warranty so the repairs were done free. A new injector pump was installed with ceramic innards and the mechanic told me he had installed several on oil well service trucks that have more than 150,000 miles on the pump, Told me the new pump would outlive the truck. Maybe they think I,ll stay with them and replace someday w/ a Duramax. THEY'RE RIGHT!!!

this is a good one 1995 6.5 diesel after the truck sits for about 8 to 10 hours and you start it, it will run for about 3- 5 minutes then stall or stumble and run like it's starved for fuel. It will either smooth out or restart with no problems and run fine the rest of the day. This happens every day after the truck has sat for a period of time. I have replaced the pmd, all fuel lines, though it could be the pick up tube in tank, but ruled that out because doesn't matter if full or empty. replaced the fuel pump in the frame rail. Don't think it's the injection pump because it would do it all the time not just in the first few minutes of use. like i said only does this after first few minutes and runs great the rest of the day. Does anyone know if there is a one way check valve in the pick up sending unit in the tank? That's my only though could be bleeding fuel back into the tank, then when it's fired up it sucks the fuel but traps air in the line also and causes problem...help....

My 94 K-5 also is starting to stall and not start and dying while idling. 394.000 plus miles.
I do not think it is the injector pump as I have replaced that twice - once at 102,000 and again at 247,000 miles. This does not act like the same problem. The first two times I had a service light and the cruise control would not work.
I have recently replaced the lift pump, fuel filter, air filter, low oil pressure switch to no avail. Just got to keep trying. Runs great on road.

I have a 95 chevy silverado 4x4 with a 6.5 turbo diesle, it starts fime but is surging as if its cutting off and on during accelaration and driving at various speeds. As it warms up it slowly stops surging and seems to run fine, until u turn it off for an hour or more and it starts up again. I replaced the injection pump 40,000 miles ago and now has 202,000 miles, It seems to have started after i replaced the westgate valve. Any Answers, jesse

Guys - whats the story here. I am TOTALLY scared to buy a diesel (especially a GM diesel). For sure I'll only buy a truck that uses GAS!!!
Seems like everyone that has ever owned a GM diesel has payed up the ass to barely keep them idling...

I have a 1996 6.5TD it's a piece of junk. Bad PMD recently overheated and blew the turbo(loose turbine in the turbo wasn't like that a week ago. I'm not sure if it overheated because of bad fuel mixture but I know it wasn't the cooling system. My question is however can a bad turbo oil seal cause a lot of blue/white or black smoke, or could this be the PMD.
GM told me that the pump was only warrentied for very spacific failures and if it wasn't a warrentied item I would have to pay for service/ testing. I think that all the people that are having these problems should get a permanent fix from the dealer not a shot term bandaid. the only way to get this is if all the owners get together and complain. We are all out a considerable amount of money here right......do we plan on doing this forever, ford and dodge owners don't have this problem, why should we.

Thanks for the advice. Ive ordered the switch.I had previously ordered a pmd and remote mount as I was quite sure that was the problem.I live on an Island and it's expensive and time consuming taking it to a dealer or big shop on the mainland. I will install the switch first(where do I look for it on the block?) If that doesnt cure it I will install the pmd kit. Past that I guess I will be taking another day off work and heading to the ferry terminal. On the phone, the dealer said "sounds like the injector pump", But as I said, the vehicle srarts and runs just like new except for random instant shut downs,like you said....like turning off the key....wish me luck.

Well I guess I spoke too soon. Yesterday my Suburban started stalling again. I have been trying to think of what can shut this engine down like you turn the key off. And when you start it up it runs fine. I have read this whole forum and nobody has mentioned the theft deterent system on the newer trucks. Can't this shut your engine right off by killing the fuel delivery? I also don't know why my truck ran so good for about three weeks after I changed the oil pressure switch. (I thought I had it) I have had a computer (scanner) attached and have seen nothing unusual while running OR stalling. Any GM diesel mechanics out there? Thanks

CAN ONLY SEE THE AIR MUST BE GETTING IN BEFORE THE LIFT PUMP AS IT WOULD BE PRESSURIZED AFTER IT. TOOK APART ALL NEW CONNECTIONS AND FOUND SMALL CUT O RING ATCONNECTOR FORM THE LINE THE THE SENDING UNIT (BUT IT WAS NEW!!) STOPPED THE AIR FOR NOW.

I too have suffered from the infamous pmd woes.
Fortunately this random shut down has not gotten me killed yet. My 95' one ton dually is no go- cart as far as steering is concerned at 20 -30 mph with no asssistance from a stalled engine. I will openly admit that I am a stubborn fool because this has occured to me in excess of 300 times. The point of my rambling is to explain that I have learned this, The pmd on my particular truck has definitely been the culprit every time. I have purchased and relocated the pmd 3 times now. amongst all of that I have learned that over heating of the pmd causes the internal connection at the bouad to become flakey. On most of my stall occasions I simply physically wiggle/pry/stress the male connector of the pmd to put the truck on the road. This very weak band aid only works for so long. Finally I relocated my last ailing pmd to the cab where I leave it under the ac duct. This allowed for days of trouble free service as well as enabling me to stay in the safety of my truck at busy intersections. Alas my third pmd has run its course, I'm sure gm would prefer that we all buy new trucks and I would normally consider this a good option however I am sure that someone somewhere knows the real problem that seams to plague so many of us. I am calling to that person! Save our trucks and thereby your reputation as having the longest lasting trucks on the road and prevent the chevy faithfull from buying elsewhere.

I READ THAT IT MAY ALSO BE THE OIL PRESSURE SENSOR KICKING OUT THE LIFT PUMP MAKING IT RUN AWEFUL UNTIL I SHUT IT DOWN AND LET IT COOL A BIT. REPLACED THAT AND CODES WERE STILL COMING UP AND WAS ADVISED TO REPLACE THE COMPUTER (PARTIAL REASONING IS A SHORT LAST WINTER SNOW PLOWING AND EVER SINCE THAT IT NEVER REALLY RAN THE BEST) SHORTED OUT COMPUTER ?? i GUESS I'LL TAKE IT OUT FOR ANOTHER RIP WITH A LOAD AND SEE IF IT KICKS OUT AGAIN AFTER 1/2 HR. THE PMD IS THAT THE BLACK BOX ON THE SIDE OF THE INJ. PUMP? I HEARED THAT CAN BE RELOCATED TO THE FIREWALL TO KEEP IT COOLER THAT ON THE INJ.

I am having the same stalling problem with my 96TD Tahoe. While driving it would start missing. At one point it knocked and pinged for about 5 minutes so I parked the vehicle for a few days. I drove it again and there has been no knocking or pinging since. I could drive it to and from work one day and everything would be okay then the next day it would start to hesitate and at one point stalled on me, but it started back up. It was diagnosed at a Chevy Dealership with error codes P0251, P0370, P1216, and P0236 but they wanted an arm and a leg for replacing the injector pump. I took it to a diesel injecton repair shop and they too confirmed that it had a bad injection pump. But they also added that the wastegate was stuck closed and that the solenoid was okay. Has anyone had the above codes and if fixed will the stalling go away. Any insight on the possible wastegate problem?

I could drive it to and from work one day and everything would be okay then the next day it would start to hesitate and at one point stalled on me, but it started back up. It was diagnosed at a Chevy Dealership with error codes P0251, P0370, P1216, and P0236 but they wanted an arm and a leg for replacing the injector pump. I took it to a diesel injecton repair shop and they too confirmed that it had a bad injection pump. But they also added that the wastegate was stuck closed and that the solenoid was okay. Has anyone had the above codes and if fixed will the stalling go away. Any insight on the possible wastegate problem?

sounds like Eric has some good deals on 6.5s.
the stalling trouble is most likely the the most common part to fail on the 6.5, which is the PMD (pump mounted driver aka FSD fuel solenoid driver) the best and only lasting fix is the PDC pump driver cooler from www.duramax.bizhosting.com

I have a 1995 GMC Suburban with the 6.5 diesel, it started hard and when it was running it would cut out.Did not show any codes, pick up pump, fuel filter, and oil sending unit all replaced.
Decided to drain tank, found all the fuel lines going back to tank along frame rail were almost rusted off, and tank was almost rusted through.
Replaced tank, fuel lines, and brake line along frame rail, so far truck seems to be running alright. Hopefully this will help someone else, I only owned this vehicle a couple months, and already invested almost $ 3000.00 over purchase price.

I have a 94 6.5 TD and get a code 29. Replaced the MAP sensor and still get the same error code. It seems like the lift pump is running alot. Hard to start and no power , with enough smoke (bluish/white) to fill Marlboro Country! This began while curing a vacuum leak that was causing the waste gate not to function. I miss the black smoke now. New fuel and air filters, replaced intake gasket and am ready to change the lift pump. If I open air bleed on fuel filter with lift pump running it fountains about an inch high. Anyone know if this too little pressure? Also I may have been too aggressive with a concentrated biocide/anti-gel/injector cleaner. But it acts like timing is off or starved for fuel. I love this truck when it's running properly. Thanks!
