be slightly careful with assuming the oil pressure sender switch is bad. i had an 87 that had one go out but it was set up to give the engine fuel for something like 10sec then shut down when it didnt read oil pressure. if your not getting and fuel even on start up it may not be the oil pressure sender (just my $.02) from what i have seen of these type issues at work i think jerry (hotrod) is on the right track
