Replaced the Fuel Pump, Fuel Filter and relay, No fire to the fuel pump in line fuse but the fuse is good. Truck wants to start. I need to know what the ground is on out side of the fuel pump. Harness? connector? There is a gray, Purple, and a black with a white strip what is ground? Or how do I fix this problem? Any suggestions would be great.

Thanks
Scott

The gray and black should operate the fuel pump. Gray being the power feed.

Now, you DO realize that this only powers for 2 seconds when the key is first turned on and doesn't resume until the computer sees a tach signal from the engine.
