Have you checked the coil pack and the module to see if they are getting voltage and a ground signal ?

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.

SOURCE: 94 buick regal grand sport

sounds like the same thing that was wrong with the 94 GS i recently bought. found the crankshaft postion sensor to be bad. it controls your electronic spark timing which would allow it to turn over with out starting.
also does your stall when you are stopped and at idle or while at driving speed or both? mine would stall at idle and driving speeds. Changed that sensor and have not had any more issues with stalling. sensor should cost around $30-$40 dollars at your local autozone, takes about 2 hours to change just need to pull the harmonic balancer pulley (make sure to use the proper tool or you will bend the pulley) and the sensor is behind the pulley. you will gain easier access to doing the maintenace buy removing the passenger front tire and the little splash gaurd directly behind the tire held on by 3 quick release fasteners. hope this helps you out.

SOURCE: 91 Buick Park Ave won't start

i just came across this problem myself the other day. i have a 91 buick park avenue that sometimes won't start. i checked several things out like cable connections and coil pack etc. etc. come to find out it was the wiring that came off the coil pack and connects to the crank sensor. the wiring that ran over top of the water pump had finally heated up so bad the coating on the wires had melted and when the engine got hot enough the wires would come in contact and send false signals to the computer not letting it start. after the car cools down and the wires contract it would start. so check the wires from the coil pack to the crank sensor to make sure the wires are not melted together.

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
