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.
Do you have that 9.8v lead going to the pump directly or to a relay? pictures please.

You can pull each pin out and carefully compress them with pliers.
