My fuel pump is not engaging when starting the car (because i can't hear it priming). THe fuel pump is new, so I'm thinking its not getting electricity/pwer. How exactly can I check this? I've already checked the relay and it's working. is there something beyonf the relays I can check to confirm if the pump is getting electricity?

Yes the relay clicks. IN terms of the fuel pump, which wire(s) are the ones that give electricity to the fuel pump? just so i know what cables to check. to check these am I going to have to dismount the fuel pump again?

At the relay use a jumper wire from D2 to C3 see if pump runs. If not then check gray wire for power and black for ground.

What do you mean by D2 and C3? are these terminals where the relay goes in? There's 5 little terminals there, 3 on one side and 2 on the other. How would D2 and C3 apply to those?
