Question about 1989 Pontiac Firebird
I've got an '89 Firebird with a 6 cylinder 3.8. When I bought the car 2 months ago, the guy said it had a brand new fuel pump but it didn't need it after they changed it. He said there is an inline fuse under the body that keeps blowing.
The car ran great, then one day the fuel pump quit working. I can't hear it hum when I turn the ignition on and I have no fuel to the injectors.
Is there any truth to the inline fuse or is the pump out? I'd like to know before I drop the gas tank and spend $70 on a pump I may not need.
Check the fuel pressure first with a gague the pressure should be at 40-47 psi
does any other things stop working when the pump stops?
it sounds like you have a short to ground in the fuel pump circut, check the circut for any chaffed wires.... there is a fuse in the fuse box there is not supposed to be one on thr frame rail
another possibillity is a clogged fuel filter making the pump work harder and overheating
check pressure wires and replace the filter one of these is your problem
let me know dant forget to rate me
