The truck will crank just fine, can hear fuel pump when truck turned to on, has 55psi when cranked and 51 when not cranking. Also checked to see if there is spark and there is as well as when started fluid or gas is manually sprayed in the engine starts and stays running until you stop manually spraying.

I check with a noid light on the fuel injectors have power on both sides of the engine. But wouldn’t think the front end collision would make all 8 fuel injectors fail at the same time.

Any help would be great!

Thanks,

Easton

Fuel injectors tested out all at the 12.2 to 12.4 ohms also so seem to match what the internet suggest should be the right resistance

Welcome to the forum from Iowa.

How severe was the collision? Hope no one was injured.

I am not that familiar with the ins and outs of your vintage of vehicle, but there are a bunch of guys here that are. @PNW VietVet comes to mind on this one.

Might also see if we can’t get this moved to the part of the forum that fits the question better so more folks might see it and chime in.

@NathanJax , @07Burb , @Miami-Dade , @yates ™ , can one of you move this to the proper section?

The collision wasn’t to bad but the radiator was pushed into the flywheel and just left the nut attached. Both air bags went off and the fuse box was cracked but just the case. I think it looked worse then it was but just stuck on finding the answer to why the engine can’t run on its own.

Any help would be great! Just haven’t found he answer on the internet that would match the situation we are in.

Thanks!

Check the ground wire that attaches at the driver side radiator support mount pad or the one on the drivers side engine block to the fuse box.
