The ground should be the black/yellow wire it runs from the pump to the frame rail.If the ground is not good just jump your black/yellow to ground and the pump should run.

done that and pump will run but runs constant it this right?
Expert:  Tim replied 7 years ago.

That means the pump is good.Sounds like you have a computer issue.You may need to either replace or reprogram the PCM.

if the truck runs when i ground the pump will it still need a pcm or reprogrammed?
Expert:  Tim replied 7 years ago.
If you ground the wire and the fuel pump comes on and off with the key cycle than I would just repair the ground wire and make sure the fuel pressure is correct by driving.
Customer: replied 7 years ago.
any idea where the ground wire from the pump would connect to the frame ?
Expert:  Tim replied 7 years ago.
Should be drivers side inside frame rail right behind axle
