Your car's alarm might have bad wiring or connectors. You could try cleaning & reconnecting them. Or use a multimeter to see if you can find connectivity issues.

If the alarm itself might be the culprit, having a garage remove/disconnecting it is the cheapest solution (less than a $100), having it replaced could be really expensive ...

you might have used wrong bulb

This sounds like a computer problem or bad connection, check all your battery connections and grounds. can you have it scanned for codes at an auto parts store, and see if there are any codes stored in the computer.

Sounds like a water pump ...cost around $100.00 parts and labor..

I have a 97 buick skylark with 3.1 engine, car turns over but wont start, replaced crankshaft sensor, coil module pack and checked fuel pump, but still won't fire, no spark at plugs, has anyone went through this problem and what is the cure

I too have a 97 buick skylark custom, that hasn't been cranking. Heres what I have figured out so far, so you may have the same problem. Heres the first question - Is the theft system light flashing when you try to crank the car? Cause if it is, it means the car isn't wanting to recognize your key as the correct key which is causing the car to go into tamper mode which disables fuel to the engine, in which case you have to turn the key back to the start position and wait for the light to stop flashing then try to crank it again.

P.S. i'm not sure why this other thing would be a problem but i lost my gas cap right before this started happening and someone told my that might trigger the sensor, do you have yours?

sound like powertrain control module is not powering up everytime

belt tensioner pully bearing possibly

if starter fluid made it chug, I would suspect fuel pump fuse, relay or pump, also fuel filter.
