    Car was running then turned it off for a few minutes and went to start it back up and car will not crank over. Doesn't even make a noise.

I have found the most common part failure issue with the ignition system is the crank sensor, also called by some the TDC sensor.

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.

I have a 1990 Buick Regal that stalls while accelerating. And then wouldn't start at all. After letting it cool for a few minutes it started but continued stalling. Before this started happening it was...


most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

Class car man.Try the crank position sensor it controlls the ignition and fuel delivery by sending information to the ecu in relation to the position of the crank-cam.

Go to your local autozone or equivelant and have them test your alternator.

Need location of ecm/ecu on 88-93 buick regal. parked car next day would not start,no spark , center coil bad , replaced it car ran fine for about 2 weeks, now car won't start no spark but coils test good,...


my name is David ,I live in Austin Texas and do alot of mecchanic / technician work around town. I do have my certifications and have work at dealerships and Autozone as well...with all that being said... if you are not getting spark on this vehicleand it is not likely the coils or the module. The crank position sensor the device responsible for reading the angle ( timing ) of the crankshaft. The crankshaft has notches in it that pass either through or near the crank position sensors magnetic tip. The ignition module then interprets the signal and allows signal ( electrical current) to pass into module and on to ignition coils...then on to spark plugs via spark plug wires/cables. The crank position sensor is located on the back side of the engine in the gap between the engine and transmission housing. it is held in place by one 8mm (metric size) or 5/16 standard size bolt. Use a wrench though unless you have small hands or a 1/4 drive socket set. 9.99 times out of ten it will start if there are no other issues... your welcome
