hello , can low oil cause a fuel pump to shut off? if so is there a reset...for that matter is there a rest or reboot for the cars cumputor??? running out of ideas.can you tell

I don't believe the low oil switch will prevent the fuel pump from running. The oil pressure sending unit can shut off the fuel pump, but only after the car starts. It's a safety set-up to keep you from blowing your engine from lack of oil pressure. The fuel pump relay is controlled by the PCM at key on, and after a crank signal is received from the PCM, it verifies oil pressure from the oil pressure sender, and if below spec, shuts off the fuel pump.

Rich is correct. All low oil level will cause is the low oil sending unit will send a signal to the PCM to trigger the idiot lamp on the Instrument Panel. It will not disable fuel pump enable.

What specific problem are you having?
