96 jimmy starting problem

it has the 4.3 in it... in the morning, when starting it, it won't start unless you pour a little gas in the intake then it runs fine all day. I haven't tested fuel pressure, but I would assume it's not a fuel pump because it runs fine all day after getting it "primed" and started... any ideas?

test fuel pressure....those need 60 psi to start and run good. dont rule out the fuel pump just yet. thats the number 1 reason those have issue's starting. altho it could be a injector issue(they where know for that too) but start with the basic's

 

 

instead of dumping gas down it...try cycling the key a few times before starting in the morning..see if that does it.

dont buy that cheap autozone POS! put a delphi pump in it. other wise you will keep having issue with the pump. Edited by Removed

it's deffinately the pump, pour a little gas in the intake, starts right up... starting PSI is about 30psi no matter how much you prime it... now it won't idle after the gas runs out that we pour into the intake...

 

it's a 4 door...

well we have a great tow company sponsor here. call brandon and see if he has a truck coming or going that way. he might cut you a deal.
