Oil Pressure Problems
Hello all,
I just recently had my tranny rebuilt when I went to put it back in the truck I must of hit my oil sending unit with my bellhousing, I replaced my oil sending unit and no good my gauge is still reading zero. My lifters aren't ticking so i know my truck is oiling. My truck was sitting for about a month, could my oil pump be possibly going out or could it be something else. All my other gauges are working on my instrument panel so its not a fuse. My truck is a 1993 Chevy Silverado w/5.7. Thanks!!

Have someone watch the gauge and pull the wire off the sending unit, see what the gauge does then ground the wire and see what it does it should go to high psi if all this works as described the problem is the sending unit...hope this helps... note key must be on...

Hi Goaliekiller16,
Welcome to the Chevy Forums.
As with any electrical problem, it helps to ensure a solid ground. It's been my experience that as the ground wires and battery cables corrode, for some unexplainable reason, certain systems are affected first.
It's almost as though in a 12V system, different segments of the ground wire are used dedicatedly by specific, set systems in the car, and as the wiring corrodes, different specific systems on any vehicle given are unexplainably affected first. Case in point: I had an old Dodge, when the negative cable went bad, the radio was always the first thing to stop working. It happened a couple of times, always the radio.
New Battery Cables and a engine-to-firewall ground strap are cheap insurance, especially in vintage vehicles.
This is not a cheap shot, I've already changed my battery cables and firewall ground strap in my 04. I've found that your Alternator,Starter, and Battery will also last longer if they aren't fighting increased wire resistance due to corrosion.
