Died and will not start - need help
Hi Guys,
This is a new to me '94 f250 turbo diesel and has a '96 remanned 7.3 powerstroke engine. I've put a few hundred miles on it since I got it and driven for an hour straight with it, all with no problems.
Yesterday, driving down the freeway @ about 45mph, it began to sputter, lose power and stalled out. Cranked strong, but never started. I had it towed home. I am not a mechanic, but can follow directions.
By now the battery is starting to go low, but when I turn the key to the on position, a relay on the driver's side clicks, then a short pause and there is a much lowder click from the brown cylinder pointed to in this picture:
powerstroke - Keith_Z's library
I do not hear any fuel pump either in the engine bay or from the tanks. I do not know for sure if a should. I took the cap off where the fuel filter resides and that is completely full. Both tanks have plenty of fuel. Switching between tanks does not help. All fuses seem fine. I switched relays around and that did not change anything.
When I crank it, the tach needle does move with the engine revs.
Any ideas - much appreciated.
Thanks, Keith

Hey kzack,
Sounds like something's up with your fuel to me.
That relay that you mention is your glow plug relay, that should click like that no questions asked
Fuel pump is driven when the engine is turning, its not like on gas cars where you would hear it prime up the system.
What i would do is spray a little bit of Ether Quick start fluid in to the air filter and see if that would fire it up, if it does, means you have good compression and no mechanical problems so then it must be your fuel... and also by the way it stopped on you.
Diesel engines dont just stop like that, there are 2 elements that need to be constant, fuel and air
if you stop one of them, the engine will die, so if its not air then it must be fuel

Thanks for the help guys.
I would be really surprised if it was something mechanical with the engine. As it died, there was no metal to metals sounds or any unusual sounds - just as though it ran out of fuel.
So if I understand correctly, it has a mechanical fuel pump that works off of the turning of the engine. Is it possible for this pump to go bad?
I've read some about the cam position sensor, but as I stated, the tach does move with the turn of the engine.
I've also always thought using ether is a bad idea.
I'd like to solve this with all of your help. Is there something else I should check?
Thanks, Keith

Hey I know it's bad but when you're stuck and youre troubleshooting it will help you eliminate possibles
it also depends how much you spray in there, when i use quick start i always have someone spray it or myself just small shots as its cranking not constant spray
And, in my experience, my dad runs a trucking company and quick start is used as OEM equipment controlled with a switch on large 12.1L diesel engines such as Detroit Diesel Series 60 to start em up on super cold winter days as last resort

well yea, got a point though, but i was generalizing.
And this HPOP stuff that ford put, its so complex and they over-engineered it because they probably didnt want to redisign the whole engine, hence all the problems with this system.
Darn a normal mechanically pushed injector woul'dve worked so much better

Check for codes, then check ICP while cranking, Check for tach signal to the PCM, See if the injectors will do a buzz test, and test fuel pressure. You will find one of these will lead you to the problem.

I'll try the ether if I have to. I do have some on hand, but I'll try some other ideas first.
craftsmangary, I don't know how to do most of what you suggest. I just don't have the experience yet. The check engine light is not on, nor was it on. It does work though. I have an obdII scan tool, but I don't think that connects to this truck.
oldbird1965, what is an IPR ?
What do you guys think about the cam sensor?
Thanks, Keith

I've read some about the cam position sensor, but as I stated, the tach does move with the turn of the engine. There has been some bad CPS and tac still moved
I've also always thought using ether is a bad idea.It is with a glow plug system and a diesel will get depended on it if used a lot

Detroit does not use glow plugs they use grid heaters. With glow plugs it can ignite the starting in the cylinder and destroy the engine

Thanks again guys,
I plan to check the fuel pressure in the morning after the batteries charge over night.
I might also order a cam sensor since people suggest keeping one on hand anyway.
