Engine Mechanical problem
1993 Chevy S-10 6 cyl Four Wheel Drive Automatic
1993 s-10 Blazer, 4.3 code w, the fuel pump isn't running at all. It completely quit running a few times as if you just shut the key off, and now the fuel pump doesn't run even with the switch on. It will start and run with a shot of starting fluid and then die. The pump doesn't make a sound at all. The fuel pump relay can be heard clicking when cycling the key switch.I cleaned off the ground connection and even tried to ground to a different spot on the frame with no luck.I unplugged the electrical connector and and checked voltage with turning the switch on and got 12.8 volts after you heard the fuel pump relay click. I tried running a positive wire and negative wire from a car battery to the 2 prong connection off of the fuel pump and got nothing, that is if even that was even a right way to get it to work?The pump was put in about a year and half ago and maybe had 3,000 miles on it and had a full tank of gas put in right before this started. The engine only quit running agout 4 times before the fuel pump would not run. How is the relay tested properly to see if it is working? Thanks.
have the same problem?
