ground wire for fuel pump

[Bobby123]

I was trying to find out why I was not getting any gas to the engine and it turned out to be that the ground wire to the fuel pump is not getting a good connection. So my question is where do I need to go to fix this connection on the truck. Is the connection on the frame, near the motor I have no idea.

There are many places where grounds are used.  Some are on the frame, fire wall etc.  If you are positive that its a ground issue, you can utilize the frame if need be, but it would be recommended that you ground to a place that will get the least amount of corrosion.  Before you do any of that though, you may make sure that the plug in connection is not the culprit.  You can check your wires about 3 feet from where they plug in. If you are getting a good solid ground there, then it probably is at your connection.

If you can get a diagram (not a schematic) showing the ground location would be doing it like GM did it. Getting that ground to and common ground may not work  or work correctly. I don't know if GM uses isolated or dedicated grounds on anything but the radio speakers. Look around there should be a screw or other indication like a unused connector with a wire pulled out of it.
