Where is the fuel pump relay and fuse located in a 1992 Pontiac Gran Prix?
Country: United StatesMake: PontiacModel: Grand Prix GT
Hello, my name is XXXXX. XXX you tell me which engine you have?....3.1L or 3.4L?
Assuming you have a 3.1L ..... The fuse and relay can both be found in the Right Hand side underhood electrical center.
i am right under the hood let me check
the right hand side would be considered the passenger side
I found it---too easy. I just replaced it same result....no start. I can squirt hot start in the EFI unit and it will start right up, As soon as I quit squirting the ether it stalls immediately. I just replaced the fuel pump and sending unit...No luck.
I am a pretty good backyard mechanic and this one has me scratching my head
is fuel pump running?
what is fuel pressure reading?
Have you verified power at the fuel pump harness connector (12volts on gray wire) while cranking?
i can hear the fuel pump running...Let me turn the key and listen real close. yep its running with the key in the on postion
I can get gas to squirt from the fuel rail valve.
need a pressure reading if possible. Should be 40.5 to 47 key on engine off.
Did you replace fuel filter along with pump?
did you need further assistance?
yes...i replaced the filter
i am sorry my internet connection was acting up
my pressure gage wont fit on the valve :(
did you check all fuses?
i checked all the fuses underneath the hood and also looked at the ones in the glove box
i am not sure what your initial problem was, you merely asked for locations for relay and fuse. Tell me everything that has happened up till this point and I will try to further assist you the best I can.
i will go get my buddies pressure gage and get back to you. I gotts go. Tell me your name and I will request you again.
I will pay for this session
