The oil pressure switch is located above the oil filter. You need a special socket like this one to remove it. You can buy it at Autozone for about $5

SOURCE: will start then dies

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

SOURCE: Buick Regal dying

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

Check all vacuum lines for leaks. Check spark plug wires for and spark plugs that may be worn and causing idle misfire.

How do I tell if my rear main seal is leaking in my 96 Buick regal


1. Are you losing oil? Have you been told this seal is leaking? This seal is located between the engine and transmission connection. This seal will be soaken wet with oil if failing. Your motor is probably the GM 3800 V-6...this motor is not known for excessive rear seal problems. Hope this helps.

How do i remove the oil pan from a 96 buick regal 3800 series?


I was told it's about a 3 hour job to change the oil pan gasket (on a '95 Regal w/3800 ). It says you must disconnect the power steering lines (because they run along the frame by the oil pan and get in the way), drop the subframe, and raise the engine to get the oil pan off. good-day ! thats GM for ya!! lol, The frame is in your way and the only way to get it out is to move the frame.

It get oil from the camshaft-lifter oil galleries. What is the oil pressure lbs.? You probably have a stopped up oil pick up strainer in the oil pan. Always use a delco filter and not a fram filter.

If it is not on the front of the motor, it is more than likely on the back of the motor. Just jack up the car (be sure to put a jack stan under for safety) then crawl under and you will find it
