The trick is to get the kids to help with the repairs in hopes of starting them on their way to being self suficient auto techs or at least able to deal with repair shops intelligently. Then dad can rest! I have a friend who is constantly visiting the Crazy Rays wrecking yard here for parts damaged by his new drivers. Last week he got a hatch door a hood and a headlight assembly. Now he needs a pair of aluminum wheels that had a run in with a curb. Bt at least there's nothing to diagnose except for bad driving.

You are right about the fuel pressure being a sneaky thing to diagnose. On the 4.3 CPI engine that runs at much higher FP (something like 50-60 psi) a slightly low FP (by 10 or 15 psi) will get you a no start. I had that one and it had me going (or not going!) for awhile.

[QUOTE= If is was not for keeping your kids in vehicles, what would dads be good for, right?

Paininthebrain, I too had that problem several years ago with small chevy. Yes, when the fuel pump pumps the fuel right back in the tank it will not make the correct amount of fuel pressure for the TBI system or injectors. Not knowing what is wrong and how to fix it can be a hardship. I have felt your pain.
