My son has a 94 Buick Regal with a 3.8 litre engine.
Recently, the car stopped running (while on the road). He had it towed to work. When he tried again, it started and ran for a day. Then it quit again.
Troubleshooting revealed that there was no spark. He replaced the crank sensor and ignition module, but this didn't fix the problem. He suspects that there might be a problem with the ignition key chip/computer, but he's not sure how to check this, and doesn't want to throw any more parts at the problem. He tried reading the trouble code using the "check engine" light, but no trouble codes flashed (perhaps he's not initiating the sequence properly - any help here?).
1. Does anyone have any ideas/experience with this kind of problem?
2. If the key chip circuit fails, will it prevent the engine from cranking, or just from starting?
Any ideas/suggestions would be welcome.
