Kinda did the same with my '89 Firebird. Only I bypassed the computer and
went from the relay to ground. Just hook up a toggle switch between your
power source and fuel-pump... works like a charm, and only costs a couple
bucks for the switch and wire. Mount it somewhere on your dash, and don't
forget to shut it off..... not that I've never done that before.....
