 Subject: Ford 7.3 Stalls, no apparent reason
Message:
I have a 95 Ford F-250, 7.3 liter Navistar, 88,000 miles. Last two months the engine would pause during excelleration, particularly with load (10,000 pound trailer). Now it stalls fairly regularly, either at idle at a light or at 6,100 RPM -- running on the highway. Routine maintenance is up to date. Any thoughts?

i have a 2000 powerstroke and it only hits 3100 so maybe ease off of the throttle

you may try checking a few sensors like throttle position sensor, or mass air flow sensor, and also cam and crank shaft position sensors. And also if your check engine light is on take to a autozone and they will do a free dio. test for you.
good luck!

My '99 F-250 PSD has stalled twice now in just one week. The first time I was clinbmg a steep incline in deep snow and she was really churning all four wheels and at the top of the hill it sputtered and I lost the ability to accelerate. It just sat there idling. But it leveled out in a few seconds and recovered. I was puzzled by what had just happened. I figured it had hiccuped because of a sustained 2900 RPM run. Now the second time was on another steep incline on dry smooth pavement at 2000 at 25 MPH on dry, smooth pavement. The truck quit responding to throttle input. I let it idle for a while when I finally decided to turn it off and hopefully reset something in the process. It started back up just fine. Now I am going to take it in to the service center and see what they say. I have armed myself with the information from the posting here. I will post back my results. Bryan

I had the same problem... look into changing your cam position sensor on the bottom (at the bottom of the block)front of the engine. Once I replaced that the truck ran fine.

There is no crank position or mass airflow sensor on a first gen powerstroke. New 6 liters do have them but that is another story. Your problem is more than likely a cam synchronizer(sensor). Lastly SAY NO to parts changers and take your truck to a FORD TRUCK dealer to have your truck properly diagnosed and repaired. It will be cheaper in the long run.

I purchased a 2001 Ford F-250 7.3 approx. six months ago. I've only put 3,000 miles. Mileage currently is 57,300. It ran great for four months, then suddenly began stalling when coming to a stop or at idle at stoplights. My dilema is that I bought it without a warranty(previous owner let it slide). Ford will sell a warranty for approx. two thousand dollars. Should I get a warranty OR just get the current problem fixed and monve on.

I had that problem and to fix that problem I had to replace the oil pressure sensor for the high pressure oil pump. I believe it was on the drivers side front of the engine between the pump and the valve cover

I have an 01 ford deisel 7.3. I changed out the batteries approx two months ago and now the truck will go along smoothly and will shut off (like a light switch) and takes fifteen minutes to re-start. You have to let it sit, as if to cool off--could this be some type of relay. Other times it will go along fine, then out of the blue-cuts off. The fuel/fuel filter is fine. When it does cut off, the motor will turn over and over until you let it sit a bit. After sitting over night, it will fire right up and go for maybe a day, and then start all over again. I noticed one time that it shut off going about 60 mph and I kept punching the accelerator and it restarted-then cut off. A 30 minute wait then. It's such a good truck, what the hell is this simple problem.

My 2001 F-350 Diesel will stall when climbing or when I am pulling a load, alot on the freeway, I will die and then I will have to put it in neutral and it will fire right back up. Also ,it seems I will loose poer often at lower to mid rpms, I will then have to take overdrive off or punch the throttle to get some power. I am thinking cam sensor. It has 61,000 and has done it intermittly since 35000 miles., Any suggestions? Dealer said run it till it dies and have it towed in. I am thinking this is unsafe advise..

I have had intermittent stalls for about 3 months. Thought it was bad fuel, or fuel filter, but changed both and still not solved. Truck is in the shop today. I will confirm what they indicate the solution is. 143,000 on 99 F250 and has been occuring for the last 10,000 miles. Service Engine light comes on after about 2 stalls. Frequency of problem increases, but can also go for 1 week without issue, then 5 times within 50 miles. Will update with results.

I had mine repaired. It was the cam shaft sensor. This is now pretty well documented issue.
While some note above it was during a load, mine stalling was occuring without any warning.
I had 142,000 on a 1999 F-250 super duty.
The computer also indicated an oxygen sensor was bad and I had that replaced. Total cost ~ $700 including the labor. I believe the cam shaft sensor itself is NOT that hard to replace.

I had the same problem. Stranded! cam position sensor was it. This is apparantly so common that several people say keep a spare on the truck.
$140.00 at parts house. $70.oo on ebay if you can wait. Very simple to replace. (less than 10 minutes.) 10 mm boxed wrench. Located on front of motor, passenger side. Lay your head on the inside rim of right front tire (feet at left tire)
and look up. has a metal bracket with point.
use screwdriver to help pry out. I replaced in 8 minutes. Of course it took an hour to pull home and figure out what to do. good luck

OK Boys - How often do I have to replace the CAM Sensor??
My 01 7.3L Excursion has done all the things everyone on "Diesel Doctor" is complaining of - in May 04, left me stranded and the "fix" was to replace the CAM. In October 04, left me stranded again - this time it was the high pressure oil regulator pump blew all the oil out (nice mess!). Friday night, a repeat performance and Ford says its the CAM sensor again. But, the warranty is 12,200 miles and I've driven 15,000 miles since we put the last CAM sensor in . . . Should I be expecting to replace these once a year????

I just bought a '99 F350 with 120,000 miles. It seems to stall when ever it feels like it; stop lights, driving slow up hill with no load, driving hard up hill with a load or coasting down a hill. I just don't see a pattern. I replaced the fuel filter, had the injectors and glow plugs tested and changed the station I was purchasing fuel from. I will try the cam sensor next. From the above postings this sounds like a viable option. Thanks

7.3 common problems and cures
1. Engine dies or runs rough intermittantly- Replace cam position sensor aka CMP. International part number 1825899C93 is latest version I have part number for.
2. Engine defaults to idle from any rpm and throttle no longer responds unless engine is shut off and restarted- Throttle pedal assembly related, almost always due to a conflict in readings of the idle validation switch and throttle position sensor. Ford uses a microswitch as an idle validation switch, it is part of the throttle pedal assembly and dust/dirt/lint/toe jam etc can cause the microswitch to stick intermittantly causing default to idle. Clean the switch with some electrical contact spray or replace as needed, Ford doesnt sell the switch separately and the complete throttle pedal assembly must be purchased.
3. Low power complaint when engine first started when cold. I have not seen this on Fords yet but have on mid90s T444Es. The engine backpressure control solenoid in the turbo pedestal starts to leak internally allowing oil pressure to close the turbo exhaust valve cutting off exhaust flow. Disconnecting the actuating rod is a temporary fix but the back pressure solenoid eventually starts to leak oil externally and turbo pedestal replacement is only cure. Also International has come out with a retrofit turbo up pipe kit to eliminate those pesky exhaust up pipe leaks at the turbo Y manifold donuts, I dont know if these also fit corresponding years of the PSD.

Lay under the truck, head by passenger front tire, feet towards the bumper. Look up under the harmonic balancer can't miss it. 10MM socket and a screw driver to pop it out.
