Re: Help on G30 with 7.4l

Yes the CTS was replaced and tested. I also put on new leads.
One thing I am seeing and I don't understand is the fuel pump set up on these TBI units. I have 12 volts going into the fuel pump relay on the orange wire, but only 9.5 volts coming out on the gray wire. THat is what I am seeing all the way back to the fuel pump with the key on , but not running. I thought it would be 12 volts. I am thinking that that voltage is low and thus could be reducing the fuel pump efficiency or that maybe the fuel pump relay changes the voltage to 12 volts when running. It's a new fuel pump relay also.
