This car is supercharged. Replaced oil pump, oil pressure sensor, PCV valve, gaskets, thermostat, vacuum hoses, oil change and filter, spark plugs, radiator fluid, temperature sender, throttle body actuator, and a few other things. Still zero oil pressure. Any ideas?

Hi,

When the engine is running, do you hear any ticking or knocking from the engine that would indicate no oil pressure?

Take a look through this link that discusses engine noises. See if there is any that mirror what you are experiencing.

I noticed the miles on the vehicle is high. It truly be the bearing are worn and not allowing pressure to build. Let me know if you checked pressure using a mechanical oil pressure gauge.

Take care and God Bless,
