Question about 1989 Ford Mustang
Runs good why would it have no oil pressure after warm up
I hope you have made certain you have adequate oil in the engine! That determined, I am betting your pressure sending unit is defective. To know for certain, you will have to test the actual oil pressure with a guage. Remove the sending unit, attach the guage. It is possible you have a worn oil pump, a weak relief valve spring, or something preventing the normal flow of oil... but chances are it is a bad sending unit. Do you have a guage or just an oil light?

It could be anything from a faulty oil pressure gauge, to a mechanic's trick to keep you from finding out the engine is soon to expire. They sometimes unplug the gauge on purpose. Fords can run a little low on oil for a while without signs or problems. I'd start by checking your oil. If it is not low on oil, there is a sensor on the engine block you might want to replace, It should have a wire hooked to it. That is your sensor. If this doesn't work, go to the gauge itself.

If your oil pressure gets to low it can turn off the fuel pump. This may also have saved your engine. The ECM turns on the fuel thru the fuel pump relay for about 5 seconds. When engine is running oil pressure sender supplies the voltage to the pump. When engine shuts off check oil pressure and voltage to fuel pump.
