The oil pressure switch is only a backup incase the fuel pump relay fails. In a properly operating system, the oil pressure switch does not supply power to the fuel pump.

Did the truck run when your buddy parked it? Or did it get parked because it didn’t run?

The fuel in the tank could have went sour and killed the pump. You need to drain the tank and put fresh gas in it anyways, so you might just throw a pump in while you have the tank out.

Double and triple check that your distributor is timed correctly.

Have you checked compression with a compression tester?

Do you see fuel being sprayed out of the injectors?
