Seems like most everyone has a problem with the fuel pump going out. Well mine will not shut off when the switch is turned on initially, the pump usually cycles on then off but not now for some reason. I thought the MSD box was bad but I sent it off and they said it was good. Also I dont have a spark except when the ignition is cut off. Is this computer related or what? I have an aftermarket fuel pump if that matters, and I also replaced the fuel pump relay.
