I can't get the fuel pump to kick on. I've replaced the engine, relay, fuel pump, and the computer but I can't figure out why the pump won't turn on. The car is a 1999 Pontiac Bonneville. Do you have any clue to what it could be?

make sure you have power at the fuel pump itself, if you do then change the pump.

changed the fuel pump. This fuel pump works. I hooked it up directly to a battery charger and it kicks on. I changed the computer thinking that would do it but still nothing. Anybody else got an answer?

check to be sure the wire harness at the ignition switch is firmly connected. i have a friend who has a chevy pickup that had the same problem and it turned out to be a loose connection at the ignition switch at the bottom of the steering colume.

fuel pump relay?
