Okay, I have a 1995 Suburban with 350 tbi engine. I just had a new crane compucam installed, and took the sub on a road trip. It ran great, until all of a sudden, the oil pressure just dropped to about 5-10 psi. Checked the oil, and it is in need of a change. Interesting thing is, however, when changed, with a completely cold engine, it still only pulls about 15-20 psi. Any ideas? This is so sudden, because the sub only has 90k on it, and has been babied and garaged. Help!!!! :eek7:

First thing is to check the pressure with a mechanical gauge to rule out a sending unit or gauge problem.

The sending unit is at the rear of the engine and it is possible that the wire is not connected properly causing a false reading.
