Can a relay intermittently fail? I'm trying to nail down a issue I'm having .which I believe to be fuel related. And the fuel pump been replaced with a OEM so I can rule that out.. on a few occasions I've sat in the car ,with the key in the on position (Not started) and I heard the fuel pump prime several times all on its own..or is this car possessed lol

No. 1-1


yes they can. And so can ignition switches not powering the pumps correctly
