How to fix ground wire from fuel pump connection?
Same with the power wire from the relay to the fuel pump connector.You can also try sliding the wire between two fingers while slightly bending the wire to feel for a soft spot but this may not work due to the fact that it works sometimes so the bad spot isn’t real big yet. 5 people found this helpful.
How is a fuel pump connected to a relay?
4. Run a wire from pin 87 to your factory wire that you cut that runs to the fuel pump. Now to explain what you just did. The relay is just like a light switch. Anytime it receives 12 volts on pin 85, it will turn on the switch and make continuity between pin 86 and pin 87 on the relay.
Is the fuel pump grounded to the frame?
The fuel pump is grounded to the FRAME so the theory is that I am adding a secure ground to the FRAME so that all are securely grounded. The ground straps were only 3 bucks each. No great investment for a stable electrically grounded system. 5 people found this helpful.
Why do I need to wire my fuel pump off the battery?
Motors running right on the edge of tuning could go slightly lean enough to start detonationin the motor and cause a total failure. The best way to avoid this is to wire the fuel pump to have a dedicated voltage line right off the battery so that it consistently performs. How to start Re-wiring your fuel pump
Where is the fuel pump and relay wire?
If power is put to gray wire back at frame rail near pump it will run and engine will start. Had no ground to terminal 35 of relay. Replaced PCM and got ground. Still have no bat to terminal 35. Have jumper-ed term 30 to 76 (wire that is supposed to run to fuel pump and pump is not energized). Checked ignition 1 and ignition 2 fuses and are okay.

Why is my fuel pump relay not working?
1997 Chevy Express 2500 Van 155,000miles, Engine died in parking lot, we installed a new fuel pump, but noticed no power to Grey wire going to pump. Check the relay and it bench tests fine, however, no power is sensed at the proper terminal to turn on the relay.
How can I get a new fuel pump to run?
Cannot get new fuel pump to run. Relay will not energize and gray wire has no bat on it. If power is put to gray wire back at frame rail near pump it will run and engine will start. Had no ground to terminal 35 of relay. Replaced PCM and got ground. Still have no bat to terminal 35.
