Fuel pump wiring
Tuesday, February 09, 2016 3:14 PM
It has been a long time since i have worked on the woring for my fuel pump set up so maybe im insane and remembering something that was from long ago or just not true but at some point i swear i had to tap into the grey wire on the factory harness for my system. Roght now i have the racetronix set up but i cant find anywhere that this is the case. And right now if i jumper the relay at the front of car i hear a click which i assume is the racetronix relay but the pump doesnt run. I know when i eliminate the racetronix harness the pump works. Is the relay dead? Now i am running a cobalt wiring harness but i have been through all the pinouts and everything is good there. But for some reason i remember tapping a wire when i originally did my hahn kit and racetronix pump install

a grey wire from the front is the ground signal for the fuel pump to kick on.
