Probably you have no ICP pressure due to a bad ICP sensor possibly but I would check the codes to see if there are any codes first.

Did you find out what the problem was? My 2002 did exactly the same thing and I have tried everything that you did with the same results. There also seems to be something different with mine. An electric vaccume pump (on the passenger side fender) runs for an extended time before shutting off while waiting for the glow plugs to heat up!
ANy Ideas?
