Question about 1991 Oldsmobile Ninety Eight Regency
Its possible. to know it will have to be checked out from the crank and cam sensors and ignition module to the ECM to know for sure.

Testimonial: "I found out it was my ignition control module, which I had it tested 6 times and they all said it was good. I will put up the All Data test. Such a head ache I tell ya. I checked all wires and replaced along with two pcm and crank sensors, thank god autozone has a return policy so you get a new one for free on returns."

Well dan after 13 yrs at gm I have found a couple of these. one really got me. First I know it sounds funny but you need to pull the carpet back on the dr. and pass. side and check the ground splices as they are connected to every thing in the car from front to back. they are a black connector taped into the harness and connect all the grounds with a steel buss bar. I always cut all the wires and soldered them together and re-tape em up. this problem would sometimes come with the engine dying when trying to roll the power windows down, or intermittent window operation. Second I had one car i really lost my **** on... it would stall on the cust. on HIS dirt road for him at times. I tried a couple of sensors and a ecm as each would look bad depending on the frame the scan tool would freeze on. The only thing that fixed the car was removing all the grounds on the engine and grinding them clean, replacing all the ground ends and reassembling. That prayer i said when the guy picked might have also helped but the car never stalled again and the cust returned for his next two car purchases. this is one heck of a problem you have here-sorry. I have had to wire in lights to the grounds and powers for the injection while driving before also. remember the pink and blk. wires for the injectors is hot with the key on.

SOURCE: ecm module gone bad psooiblely
Clean and tighten your battery cables. I have a 95 cutlass supreme that did the same thing. If that doesnt fix it, the ECM may be to blame. When the ECM went in my Olds, the car would fire but only run for 2-3 seconds. Once I had the ECM replaced it was fine

check fusible links at the starter before doing any crazy wiring stuff. there should be at least two of these links atached to the hot wire on the starter. one of these i know for sure supplies power to the fuel pump.....

make sure your cap and rotor timing is correct double check spark plug routes (mistakes happen). maybe your timing is off in general.

Check the wire from the module to the crank sensor. They go bad. Usually from oil leaks. Is it saturated with oil where it goes under the engine? Also check for power and ground on the two wire plug on the drivers side of the module. It isn't the ecm or anything with it. The ignition system on the 3.1 will work with the ecm unplugged. The ignition system is a stand alone system. It sends signals to the ecm for the fuel injection.
