It can be the sending unit or the oil pump really has low pressure, have the oil pressure checked in the engine, if that is ok then the sender or the wiring to it is defective. DO NOT DRIVE THIS CAR UNTIL THIS IS CHECKED, YUOU WILL DESTROY THE ENGINE IF THE PRESSURE IS LOW. A NEW ENGINE IS ABOUT $3500.00, DO YOU WANT TO CHANCE THAT?

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.

SOURCE: i have a 1999 buick regal ls dying.

I found the problem. It was the crank position sensor. There was also a cracked vacuum hose connecting to the diaphragm on the fuel rail. Replaced both and my 92 Buick no longer dies. For the guy who's Buick was dying when using the turn signals - replace the crank position sensor. One of my symptoms of my Buick dying was when I used my turn signals. Use of turn signals places a varying load on the electrical system which messes up the crank posistion sensor if it is going bad.

Why wont my 99 Buick regal ls stay running it starts then immediately stalls out


Is your SECURITY light flashing? If so, you have a V.A.T.S. problem. VATS stands for Vehicle Anti Theft System. Try getting a new ignition key made because the resistance value has probably changed in the one you have. If that doesn't do it you'll need to get a VATS bypass.

1999 Buick Regal LS hesitates during acceleration, and stalls if come to a stop


You could always try to find a used one at a salvage yard that's in good shape. You may find its cheaper than cleaning yours altogether and if the place is cool, they MIGHT even let you return it if it isn't the issue. Even if they only credit it, at 190K, there's gotta be a few things you need for it! Just a thought! Good luck!

I have a 1999 Buick Regal ls car run out of gas


A couple of possibilities. 1st, check to see that the fuel pump is working. When you turn the key to on position (not all the way to crank the engine over), can you hear the pump? You should hear a humming sound from the gas tank . The fuel in the tank actually keeps the fuel pump from overheating. It is possible the pump is shot. It would be a good idea to change the fuel filter, as it may be plugged up from sediment from the bottom of the tank.
