20 Most Recent 1994 Buick Regal Gran Sport - Page 7 Questions & Answers

When my 94 Regal GS frequently wouldn't start for 30 minutes to an hour after being driven, it was the crankshaft positioning sensor that needed to be replaced.

I would check the bulbs, I just had a Cadillac with the same problem, the bulbs looked good, but both were actually bad.

Always look for little covers in the area that hide screws. Its likely that thats whats going on, so don't force anything or you may break the panel.

did you check the battery cables. make sure they are tight.

it could be as simple as drilling holes in your catalytic converter or replacing them. Alot of these symptoms show up because of a plugged cat. converter or fried o2 sensors

Remove and inspect the spark plugs for heavy deposits or glazed-looking interior insulators. Make sure the plugs are the proper type for this engine. Heavy carbon build-up in the cylinder heads will cause pinging. If the ignition system is too advanced, it will also cause problems. Try a different brand of fuel. High engine temperatures can do the same (caused by poor cooling system or lean fuel/air mixture). If the check engine light is on, take the car to Autozone or a similar business that offers a free scan of the computer. This may provide additional clues. Hope some of this helps!

Your turn/wiper switch is bad in the steering column. It's not too hard to replace if you have a steering wheel puller. Be sure and disconnect the battery so you don't trigger the air bag.

You can do them both on a Saturday afternoon. Your local autoparts store usually carries 2 brand, both with a 1 yr. warranty. I will tell you this, If you like to do it often, buy the cheap one,,, otherwise buy the BETTER one. Impact wrench makes the job soooo much easier.

check your ignition switch contacts...might also be an electrical bad connection somewhere. Also check the fuses. Check also the voltage going the solenoid or test the solenoid too.
