Hi all, Im new so here is my first question.

I am trying to locate the fuel pump relay on my 88-S10 Blazer.
I have looked under the hood with no luck. I have also looked under the dash.
Its enough to make a guy feel stupid. Anybody know where I can find it?.

:smokin:Thanks from the Stevo

Ok..I found it. I was thrown off by the relay I picked up at the auto parts store,they gave me the wrong one.

Well I checked the codes and get 34 and 22.

34 MAP sensor voltage high - pressure high/vacuum low or, 34 MAF signal high - flow low (EFI/TPI/SFI)
and, 22 TPS voltage low.

I also Replaced rusted through fuel tank and fuel pump/fuel filter. After replacement the fuel guage reads full with 3 gallons of gas in it, hmmm.

This blazer has sat for three years it was one of my many 'Ill get right on it projects'...hehe. When I first bought this truck it was not getting fuel to the motor.

Thanks from the Stevo :smokin:
