In the last couple of months my truck has randomly stalled out at low engine RPMs. I have put in new spark plugs, wires, cap, rotor, fuel filter, K&N air filter, fuel system cleaner, new oxygen sensor and I change the oil religously. The truck is a 94 F150 with a 5.0L with 80,000 miles. The truck seems to me to be running out of gas even though there is plenty in the tank. A puff a white smoke comes out of the exhaust. Sometimes it will die other times it will just stall out for a second without dying. I have taken it to my local ford dealership to run codes on it, but they found none. The check engine light does not come on while the truck is running. It runs great other than this random stalling problem. I really need to get this fixed because I was going around a turn and the engine died along with the power steering and I could barely turn and was about 2 inches from nailing another car. This problem is getting to be dangerous and I cannot figure out what it is. The only thing that I think it could be is the fuel pressure regulator, something wrong with the EGR, or a fuel pump thats going bad. I have no other ideas, PLEASE HELP!

 

It seems to be something in your fuel system, but I'm not sure what.

I think you're beginning to hit the nail on the head with the fuel pressure regulator, but I can't be sure.

I've never heard of this problem before. Maybe somewhere here has also had prior experience in this department.

Good luck, and be careful!

i have a simular problem right now and i can assure you it is a electrical problem .check you eec and relay and also bad wire or ground ,,the problem will get worse .

 

Have you been able to diagnose the problem yet, bbens?

im still working on it ,,,i definetly do not get a spark when mine dies for about 15 to 30 minutes..but my problem started out like yours and got worse.the white smoke indicates unburnt fuel in the engine so i think we are both on the same path,

 

When mine dies it will start right back up. So you think it is an ingnition problem? I also thought it had something to do with the ignition because of the unburnt fuel coming from the tailpipe. I still really have no idea though what is going on, there are just so many things that could possible be causing it, and since it only happens randomly it make it just that much more difficult.

 

try the iginition module on the distributor that was my problem before.
