Well, my car runs after I converted to a 5.0, but I have to turn the fuel pump on every time with a switch because it's not getting power. Where should I start looking? I turn the key to the ON position and I here a click under the hood, but the fuel pump doesn't "prime". I looked under the seat and there were the wires for the fuel pump relay, but no relay. so i plugged the relay out of my 89 car in and still nothing. Where is the fuel pump relay supposed to be on a 91 lx 4cyl?
