1990 Buick Regal 3.1 has rough idle, hesitates and dies when accelerating.


A lot of new parts! Have a compression test done to gauge the engine's internal condition, and go from there. If compression is good on all 6 cylinders, scan for trouble codes. The compression test may find your problem, something like an exhaust valve burned or not seating properly.

Crankshaft position sensor location


The sensor is located at the bottom of the engine behind the harmonic balancer. To the right side of the motor. You have to remove the pulley to replace the sensor.

Which Solenoid to buy???


Replace the crank sensor to fix it. It's next to the crankshaft pulley which has to be removed to replace. Next time it gets hot and shuts off , spray or pour some water on it and see if it will start. If it does then you will know what to do.

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
