Tried the jumper and nothing..fuel pump
I did the jumper between the B+ and Fp and got nothing but a couple sparks.....so is the fuel pump shot or is there more stuff I can check?

Normally if you turn your key to the ON position (right before cranking), you should be able to hear the high-pitched whine of the fuel pump. If you don't hear this it is probably shot. I'm not sure if there is a fuse or not.

Connecting the B+ and Fp bypasses all the relays and fuses. If the pump doesn't run while doing that then it's most likely shot. The only other possibility would be a broken wire. You can access the fuel pump wires beneath the rear passenger side seat, there is a small panel you can unscrew from the floor. Before you go and drop the tank it might be worth doing that and trying the pump from there. The blue wire is +12V and the white/black is ground.

Anotherway to test if you cant hear it is pull the return hose from the fuel pressure regulator and try to start, Should make a mess. (Please no smoking and fasten all seatbelts durring take off and landing ^^)
