Interior problem
2004 Chevy Truck Four Wheel Drive Automatic 74,400 miles

Had oil changed but after driving oil pressure guage drops down to zero. Truck runs fine and no different. Guage goes back up after truck cools off but as soon as driving again, it drops down to zero.

Check the oil pressure with a mechanical gauge,if normal replace the oil pressure switch. If abnormal could mean oil pump and/or engine bearing.
