The fuse is good, my bet has been on the relay, which I have no been able to find. Its very hard to find info on locations of things. Some say driver side firewall, others say somewhere under the dash. I found what I THINK may be it on the driver said dash, looks like wires head back towards tank, so I was going to try to jump the pump to see if that works, but none of the wire colors match up to what I found to be the wires to test/jump. There was also a red wire with a connector on it just hanging there not plugged into anything right next to what I THINK may be the relay.
I did not hear the pump running with the key in the 'ON' position, but I dont think I ever have been able to hear it even with it running. These pumps are pretty quiet to what im used to hearing in my performance car.
Where is the FP Relay located? How can I test it/jump it? I do have a multimeter.
