Is there any way to test a fuel relay switch to see if it is good or bad? I am having issues with my '03 Retro. If I jumper the wires the fuel pump comes on, but if the switch is connected then it won't. I just bought a brand new switch and it still doesn't work. (I know that I can just bypass the fuel pump and be done with it, but that still leaves me not knowing what the real issue is.) Any help would be greatly appriciated. Thanx.
