While driving my truck shut down a dirt back road and as I was going down a kind of steep hill. The truck just shut off on me out of nowhere and was running completely fine and now it won't start back. It will turn over but won't start and my fuel pump is kicking on when I turn the key but won't start. It's stuck on that back road right now and people are stealing my tools out of it. I can't get it home because no one will tow it for me. Please let me know if you know of something that might work or fix the problem, I usually know how to fix my truck normally but how it shut off and cranks over but won't start is bugging me because the fuel pump is working.

More than likely this is a fuel or ignition issue. Even though you are hearing the pump does not mean it is creating pressure.

So that means we need to start with using starter fluid in the intake and see if it will try to start or start and stall.

We can also check the fuel pressure to find out if this is not building pressure.

The other major thing we need to check is for spark. This could be a crank sensor issue so let's pull a spark plug and hold it against the block to find out if there is a spark when you are cranking the engine.

Basically, these two things are the most likely causes of this so let's start with these two and then go from there. Basically, this should tell us what direction we need to go if not tell us what the issue is.

Thanks
