V20 fuel pump.
« on: August 05, 2022, 06:11:06 PM »
My fuel pump has been working on and off on my 87 v20. Changed the relay. Have a good ground. So I put 2 volts to the pump and it does not work. Dead fuel pump.  What I'm wondering is I put a meter to the pump pigtail and get 9 volts. Do I have a power issue that is cooking the pump?

12-9=3 meaning you have a voltage drop which is resistance, or you are just getting poor readings.
