When you turn the key to ON the security light should come on for 2 seconds (bulb check) and then go out and stay out. If it doesn't go out, or it comes back on, then your problem could be the security system. Lets see what its doing before we go down that road.

Do the HB'* have the teeth for the crank sensor on the backsides in the 92'*?

Also check for fuel in the vacuum line going to the fuel pressure regulator.

Re-reading your first post I see that they do, did you correct the issue of why the ring was hitting the crank sensor? or perhaps is your new crank sensor is now busted too?

Tim..reread the last couple posts.. He has no fuel pressure.

Hence.. no start.

Bill, no offense but I've got 2 reason for asking that. Well ...make that three.

First, the damage was in the HB/Crank sensor area and it seems to me that we need to be sure thats fixed right before changing our focus.

Second, I think we're chasing ghosts on that fuel pressure issue. What I think were seeing here is a fast bleed down rate so that by the time he gets back to the rail, after the 2 sec prime, is low pressure and the pump wouldn't turn on again until rpm'* come up. He did jumper the pump, got pressure, and it still wouldn't run, but probably should have.

Lastly, I'm not afraid to put out a theory and learn something if I'm wrong.

So, see any holes in my logic so far?

Not at all Tim.. I thought you might have missed the fuel bleed down. You got it though and are willing to go with the ...it'll pump up enough theory. So far..about a year that theory has been workin on my truck........I won't question ya

The new crank sensor is fine and not hitting any of the fins that i straightened..... and yes i am having a fast bleed down situation...but what would cause that to happen??? and it still won't start and i need my car asap my dad is gettin mad at me for using his truck all the time. I pulled the vacuum line off the FPR and there was no fuel in the line... What next???

Have you checked what the fuel pressure is at the rail? An actual reading, not just if it shoots out or not?

Another thing to check is fuel injector pulse.
