On my 2002 the ignition switch was hanging up causing a similar situation. A shot of WD40 into the key hole cleared it up, over a year ago.

What causes thumping when you step on the breaks?
It is most likely caused by a rotor that is warped. When you step on the brake pedal, the brake pads pulse against the uneven surface, causing a "thumping" you can feel. Other possibilities could include a bad wheel bearing or a tire that has tread that is separating.

What can cause the sunroof on a 1989 Nissan maxima to open and windows start to open when the ignition switch is turned on?
Could be at least two things - Electrical short - Electromagnetic coupling between power wires for ignition and window/roof motor control wires. Turn on power bleeds onto motor contol lines and induces a electrical current onto the wires causing them to run. Just a guess

You may have a electrical short in your ignition switch or in your fuse relay box,check to see if any water may have gotten into the fuse box relays.
What is the thumping noise from the engine compartment?
I have a 95 Camaro as well with the same problem. My problem was that my cam was eating up my lifters, and then they tried to fix the problem, and adjusted the valves wrong -- thus causing the thumping noise.AnswerIf you hear it when first pulling out or turning from a stop, it could be loose or damaged motor mounts.

1996 buick skylark- the dash lights dont come on all the time - when they do come on the car will start up right away-what could be causing this?
Sounds like an electrical disconnect somewhere. You can always find a place that can give you an electrical check, but I think it's the ignition switch. Also, check for recalls. There was one recall where a relay has to be put in so that too much current doesn't go back to the ignition switch and melt the thing....
How can you override a kill switch on a 1999 Chevy Silverado?
I had a problem with my 1999 silverado bacause of a faulty fuel pump it was causing my truck to cut off after running for a minute or two. After getting under the truck and listening to the fuel pump whine I was then able to determine that the pump was in need of replacement. The truck runs great now that I have replaced the pump. I didn't know what to do for my truck to get it running right so I replaced ignition coils, control modules, and even straight wired my ignition so the relay's wouldn't cause my truck not to crank properly.
