Is the fuel pump suppose to come on when the key is turned to IGN on? I don't hear it when I do this and the car won't start. I tested the fuel pump by running a wire directly to the battery and I do hear the whirring noise. But when I plug the relay back in the fusebox, turn IGN on, I don't hear the whirring noise that FP's suppose to make.

Help?

 

You can trigger the pump with the Fuel Pump jumpered in the diagnotics box and the key turned to ACC. I don't believe the fuel pump turns on until you start cranking. If it did, you wouldn't need to do the jumper to test the fuel system. I've been wrong before though.

 

it turns on in key ON for a few seconds then shuts off till the ecu senses cranking. and which relay are you pulling the one in the front of the car just controls speed (low/high)
