Blazer Fuel Pump Fuse
Q. Dear Sir, I do not have 12 volts to the fuel pump located inside my gas tank on my 1988 Chevy S-10 Blazer and can not find the fuel pump fuse. I checked out all of the fuses on the fuse block but can not find it there.
Can you tell me where I should look for this fuse? I will appreciate any help that you can give me so that I can solve this problem and get my vehicle started and running again.
Thank You,
HermanA. The ECM B fuse is the one that powers up the fuel pump relay. This fuse is in the top row first one on the left. Also if the ECM does not receive a pressure reading from the Oil Pressure Switch, it will not activate the fuel pump relay. It assumes that if there is no oil pressure, the engine is not running and shuts off the fuel pump.
