wire harness to ECU connection
I am having a problem with the connection between my wire harness (red and blue) connectors and my GM ECU. I have 12 plus volts going into the ECU but the output lead from the ECU to the fuel pump measures only 9.8 volts. My fuel pump won't turn on with the low voltage, and the car won't start.
I suspect that I have a bad connection between the wire harness and the ECU. What can I do to improve the connection? The wire harness has been plugged in and unplugged several times and I think the connections are a bit loose now. The engine is a GM LS2 with a GM ECU.
I am looking for Ideas on how to restore a good connection between the wire harness (red and blue connectors) and the ECU. Thanks.
