Engine Mechanical problem
2002 Chevy Blazer 6 cyl Four Wheel Drive Automatic 170000 miles
Fuel pump issues. Check engine light was on, after reading code, got a new gas cap and light went off. Two days later vehicle died. Fuel pump wouldn't come on. Got a new fuel pump and plugged both terminals in and now new one won't run. I only have a test light but I do get very weak power to one of the prongs on the pump terminal (not the sending unit terminal). Fuse not blown-ECM-B- and I did try switching around some relays with no success. I do have power and ground at relay as I checked it with key on and key off but I am not really sure what its supposed to be. Does the fuel pump need to be installed or grounded to work? I wanted to make sure it was going to function properly before I put it all back together.
have the same problem?
