Question about 2003 GMC Sierra 1500
WHEN I TURN ON MY CAR IN THE MORNING MY OIL PRESSURE GAUGE WILL READ 0 AND OIL PRESSURE LIGHT WILL COME ON ONE I START DRIVING AND THE MOTOR GETS WARM THE PRESSURE WILL GO BACK UP AND IT WILL BE FINE . I FIGURE ITS THE OIL PRESSURE SENSOR BUT IM NOT SURE AND IF SO WERE IS IT LOCATED?
Any time the oil pressure is 0 you take a chance of locking up the motor. The only way to know for sure is to put a pressure gauge in the oil pressure sending unit port on the engine and see what the pressure really is. At that point you will either have the peace of mind in the knowledge that the sending unit is really bad and needs replacement or you can then contact a repair shop and tell them what your testing has revealed. I wouldn't drive or run your truck while the oil pressure is at zero.
