Oil pumps don't have a MTF remotely close to an alternator or water pump. Not that they NEVER fail, but given the fluid they move(oil) it's about as friendly an environment as you will find in an engine. What does your OBDII show? Check the sender unit. How is your oil, feel gritty? NG! Peek into the oil filler cap and see if oil is flowing over the rockers. How long have you run it with zero PSI? If you really have no pressure you will hear all sorts of strange(and nasty) sounds, and quickly, some manner of seconds.

Sender units are generally cheap, even simply removing the connectors and reattaching them could clean enough to make a connection, poor, but connection nevertheless.

So as Occam's razor tells us, when you hear hoofs think horse, not zebra :). Go toward the easy stuff first.

If the oil dipstick shows good oil level, the problem is usually is a failed pressure sensor, which I would have checked ASAP at a shop. If the oil level is very low, top it up, but to avoid serious engine damage you may need to have it towed ASAP to a shop for repairs.

I need to find the oil pressure relay so I can replace it !

It is on the top behind the intake. It is pretty far down but it is easy to get from the top side. It will take a special socket you can buy at your local parts house.

Oil pressure

30 PSI hot idle is ok, 40-50 PSI at freeway speeds hot is good. this is based on using the correct weight of oil which is 10W-30W
