How to install ground wire for fuel pump?
Get two washers and a electrical ring terminal for the wire. Drop a washer on the bolt, then the ring terminal with the ground wire and then the second washer. Grease up the entire assembly to waterproof it and install the bolt into the frame.
What happens if a wire is loose on a fuel pump?
A loose connection will generate heat at the site of the connection and not supply proper voltage to the pump, which likely will burn the wire and damage the pump, causing your engine to run poorly, if at all. Take the ground wire from the fuel pump and attach it to the nearest electrical ground surface you can find (usually the frame of your car).
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.
When did I change the fuel pump on my GMC Sierra?
I changed the fuel pump on my 1996 GMC Sierra earlier in the year. I cut through my truck bed right above the fuel pump so I would have easier access to it. For the most part my truck has been fine but I have had problems with the ground wire coming from the fuel pump. At first I thought it was just the old rusty bolt that grounds the fuel pump

How does the fuel pump control module work?
This is what I would expect, the wierd thing is that coming off the fuel pump control module I get 12v on the positive (blue wire) side and 1.4v on the negative side (red wire), yet the pump isn’t running. This makes no sense to me unless that’s some sort of default condition that the pump understands?
