After consulting my newly purchased FSM I traced the problem to either the relay or the power supply to the relay, you can hear It click but then nothing, after multi metering I found out that there wasn't any power getting to the relay what could the problem be?

Or if anyone knows which black/ white wire supplies the 12v to the relay that could be useful

Your pump is supplied by the 15A "eng" fuse. That's your black/ white wire to which you are referring..

You have two coils in the circuit opening relay, one energized by the key's start position, the other by the AFM's door switch. Either coil energized will run the pump...

If you're getting power when the key is held to start, but not after the key is released, suspect either the relay or the AFM door switch. To troubleshoot further, jumper the 2-pin check connector near the AFM & right strut tower, and check for voltage again after the key is released...

If you have voltage at the relay now, the AFM is bad. If you don't have voltage, it's either the relay or an open wire in the circuit...

Backprobe the connector at the left rear strut tower, under the sidewall carpet, the blue wire on the HARNESS side. Leave the plug connected. Check for voltage, to ground...This is your pump's power supply wire. If you're getting voltage back to this point with the key to start OR the AFM open (or check connector jumpered) and the pump's still not running, it's probably the pump, or it's ground, that's bad...

damn thanks lol, ill get on it tonight with the multi meter starting at the key switch working through the circuit
