My fuel pump is not getting any power, neither with ignition on or when I’m trying to start my car. If I got wire the grey wire to the fuel pump the car starts perfectly.I need help restoring power to my fuel pump the right way. I am not comfortable with jumping the the fuel pump.

Good afternoon,

I attached a wiring diagram for you to view.

Do you have a test light or voltmeter to do some testing?

We need to some tests to see why there is no power.

Hey thank you for your response. My car is parked at my friends house and as a result of the corona lock-down I’m allowed to be on the road for three days only. I will update you during the week. Thank you again for your information.

Hey, I managed to check my car and the EFI fuse has power, ignition fuse have power, the yellow wire has a ground signal when I’m cranking. But the light green wire does not have any power.

Okay, did you check the ignition fuse for power on both sides? This is a power test, not visual.

If there is not power to the light green, then either the fuse is bad or wiring between the fuse box and the relay.

Hey, I just want to update you. I had put this project on a pause. Last week I manage to get the problem sorted out, and I would like to thank you very much. The connection at this plug was corroded under the dash near the steering column.
