SOURCE: 93 olds cutlass . oil pressure gauge when started car todaygauge did not moveoil level fineruns perfectguage just at low end of guage

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

SOURCE: how to replace a crank sensor on a 93 buick regal 3.8L engine

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.

SOURCE: my 01 bonneville oil pressure gauge is showing 120

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:)

I have a 93 buick regal custom 3.1L. The car takes two tries to start and then once it gets going it will stop when i take my foot off the gas. Any advice?


Sounds fuel related. but, first, when was your last tune-up(plugs, fuel filter, pcv valve, air filter, check all fluid levels)? If everything has been checked, the next thing is get your fuel pressure checked with a fuel pressure gauge. Also have your diagnostic codes, if any, read by a parts store for free. A code will direct you to an engine or emissions-related problem.

I have a 1976 buick regal 350 engine and the oil light comes on when the engine gets hot and it is at an idle. when you give it gas the light goes out. could this be the oil sending unit and if so where is...


it might be the sending unit, is it a buick 350 or a chevy. 350? if a buick engine the sinding unit should be on the side of the timing cover if a chevy 350 next to the dist.

remove the oil sinding unit and install a manuel gauge and see just what the oil pressure is if below 10 psi at hot idle replace the bearings and oil pump in the engine. if this is a chevy 350 make sure you replace the camshaft bearings this is were we use to see the gratest oil pressure loss.

Oil pressure light is on. Need to check for oil pressure. How?


You'll need an oil pressure "wet gauge", remove the oil pressure sending unit on the motor and install the wet gauge where the sending unit screws into.

There is oil in my coolant overflow of my 93 Buick regal. The car has not over heated and there is no coolant in the oil when I drained it. Head gasket or could it be something else?


A common problem is the intake gaskets. Have the system pressure tested or look at the front or very rear of the engine and see if there is coolant leaking down. The gaskets for this engine are about $100 in a kit and the labor takes about 4 hours to complete. You will also need to replace the oil, filter, coolant, and if you need instructions, let me know.
