This is puzzling me: My car starts, runs for about 20 seconds and then goes dead. The radio and the door locks do not work. It will start every time and go dead every time. The window motor was removed last month-could this be cauing a short? Please help!

Egad!! That's a different problem.
I think I would pull fuses for those items and see if it makes a difference. Have never had a power window cause such a thing but there's always a first. T

Thanks, Tom. Pulled the fuses for those options-they looked fine. Have tried gunning the engine when it starts-doesnt run long enuf for this to help! It prolly overdue for a tune-up..could this be causing these weird problems?

A tune up can make a car run better but generally is periodic maintenance and shouldn't prevent your car from running.
Couple ideas:
Get a 12V test light and when the car is down test for power at both sides of fuses and especially the fuel pump fuse with key in run position. Fuses for dash lighting will be dead at both sides unless you have the lights on.
Just once in decades I found the transfer box at firewall bad (underhood) where all power enters the cabin if you find no power that would be next. On spade type connectors just give them a sight bend or twist but just a little. It should be packed with grease in there from factory and have perhaps just one hold down bolt. It's a guess but this is a common demoninator for whacked problems.
That and certain aftermaket stuff like theft controls, stereo stuff that has butchered wiring can be the source. Keep us posted, T

I will get on the latest you have suggested-thanks, Tom! So: some type of fuse in the fuel pump can cause the engine to die? I didnt know there was a fuse there!

The path should be from unfused battery power to fuse box, then on to low pressure swithc, then to a relay and on to compressor. Like Hanzel and Grettle follow the path. If you know you get power you should be able to forget all before it. T

Alrighty, Tom~the mechanic says the car wont start because of a problem in the security override system and they dont do that kinda work-so I guess this means...what? Towing it to the nearest Pontiac dealer? Is there anything I can do? Thanks for your time

If you have a factory security system a dealer will help. If after market find out what company made it and who installs them. There are quite a few. Even if I knew I could never post how to break it on the web. Best I can do for now, T
