I HAVE A NISSAIN TRUCK THATS BEEN SITTING A WHILE. WHEN IT STARTS THE OIL PRESSURE IS GOOD. AFTER IT WARMS UP THE PRESS. DROPS OFF, OIL LIGHT COME ON, KNOCKS A LITTLE.I CHANGE THE OIL AND FILTER. NO CHANGE.I HAD AN OLD OIL PUMP NOT KNOWING IF IT WAS GOOD CHANGED IT, HAD THE SAME SITUATION. DONT WANT TO JUST WAST A 100 DALLOR BILL ON A NEW PUMP, ANY IDEAS?

Sounds like engine bearing problems-Check the oil pressure wih a mechanical gauge

Yeah I havent tried that. Thats my next step. When it starts doesent knock at all. But im thinkin to my self what are the odds of the two oil pumps being bad cause I put a used one in it instead of blowin money on it
