#416, "RE: Megasquirt question re:fuel pump wire" In response to In response to 0
Originally posted by Keith2172 Will leaving the white/red fuel pump wire from the ECU disconnected cause a CEL. It's only on when the engine's running and won't save so I can't check it with my scantool. If I attached a relay to it and ran that through a resistor to ground would that work in removing the CEL? Anyone else with this problem or do we keep CEL's like a badge of honor?
If you want you can leave the fuel pump under the control of the stock pcm, this will have no ill effects. Just makes it harder to troubleshoot and test the MS.
