2 things come to mind check the negative terminal of battery and the ground wire connected to engine location varies where they connect these but will always originate from neg on battery a quick check to see if you have a proper ground connection is to take one booster cable and connect to neg post on battery and connect the other end to the engine on clean metal (be sure to keep clear of moving parts ) start engine and see if you have pressure on gage if so you must clean ground connection to engine .if this does not correct possible bad sending unit in side of block with one wire connected to it . caution ** temperature sending unit look similar so make sure with one you are taking out

Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.
Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gauge via wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.
Please rate and god bless:)
