Does a 1988 Chevy C10 with EFI have an oil pressure switch that shuts off the fuel pump if the oil pressure is low?

no, however the fuel pump has a secondary route through the oil pressure switch.If the fuel pump relay goes out the pump will run through the oil pressure switch after the engine gets oil pressure. this results in extended engine cranking time before the engine will start

With good fuel pressure then I would check to see if it has spark after it shuts down.

there were no 5.3 in production in 1988; but on a small block Chevy in 1988 you should have 22-25 psi
