What you need to do is check the oil pressure with a oil pressure tester.You need to remove the oil sending unit and install the tester and let the motor run and warm up.Check the reading on the tester with the engine warm.It should be above 6-8 psi at idle.If it is around 10-15 then you have a bad sending unit and need to replace it.If it is below 6-8 then you have worn out crack shaft bearings,and rod bearings and will need to replace them to get your oil pressure back up to normal.You can also replace the oil pump as long as you are doing the bearings and have the oil pan off.Hope this helps.Good luck.
Sorry to say that low oil presser after warm up is most likely do to bad main bearings. if other wise it is in good shape i would replace main& rod bearings and oil pump.can do it your self for a few hundred,if you would like any further assistance feel free to ask, thank you for using fix ya.
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.
