No oil pressure, 2000 duallie truck?

Mike Carr · 02-21-2013, 02:15 PM

We have a 2000 Chevrolet CK3500 duallie, 454 gas engine. The oil shows as full, but no oil pressure. SOmetimes it shows low, when warmed up, and in gear at idle. Once the revs come up, it picks back up to 40 psi. Now, today, no oil pressure at all, no matter what. In a somewhat related note, the fuel guage is also incorrect, as the gas tank will be full, yet will show as empty (sometimes hit a bump, and go up to 1/3, 3/4 etc). So I know the fuel tank guage is not right.

Is it possible there is a bad sensor for oil pressure? Is this a common problem for anyone on here? Just wondering before I spend a wad of money to have everything looked at (which I may have to anyway, but if I can save a few bucks, I would like to).

Thanks in advance.
