I took off my discharge tube, bypass, inlet tube, MAF, and air filter so I would have room to work on the sender. I also took my spark plug wires off to give me even more room. I fiddled with the sender, got back in the car and just turned the key far enough to turn the accessories on. The gauge was reading pressure...it went from 0 to 100 and pegged at 100 because I didn't have the wires connected to the sender. I plugged the wires into the sender and checked to make sure the gauge was still reading pressure...it was. FP went up to about 30 psi and stopped there.

I put everything back on and started the car again. Now it wasn't reading pressure...it was stuck on 30 psi. Even if I adjust the FPR, it stays at 30 psi. Could there be some kind of electrical cross that is causing my gauge not to read? It read pressure when I had everything off. I put everything back on and no pressure. WTF is going on?
