In need of help!!!!!! My 91 GT is getting about 5.5 volts to the fuel pump in the run position. I'm getting a constant 12 volts on the pink/blue wire, 12 volts on red wire with the key switch on but getting only 5.5 volts when i turn the key to run position. I've checked my ECU in another car and it works fine. Also tried another computer in my car with same results.
