I rebuilt the motor in my car, put it in, packed the oil pump with vaseline when I assembled the engine, primed it for 2 min (with gm prime tool and drill), got the cam sensor in correctly. The car started right up, sounds good, runs good, but my oil idiot light stays on, unless I give it a little rpms it goes off, but as soon as you let off the gas and gets to idle, it comes on again? No I haven't drove the car anywhere, and I let it run for like 3 min to see if maybe it just needed to catch the prime. Any help someone can give me would be appreciated. I think that the oil pump is not staying primed? I'd like to get this problem fixed, and take it for a drive, my black beauty is calling me.
