Hi smccall22,

If your fuse is good, youll find its one of two problems.

Firstly youll find that one of the yellow or red wires connecting the stereo to the car is not working, perhaps it has been damaged due to the car moving too much or being too old. You can test them with a voltmeter, etc. What youll have to do is to hook them both directly to the battery which will make your radio work even with the car off (so youll have to turn it off manually.)

The other possibility is your stereo may have malfunctioned and burned out. This can only be confirmed by opening it up and testing the radio with a foreign power source.

Hope this helps,

the level control is on the rear axle. If you follow the air lines from the rear shocks you will run into the air pump. On some pumps there are valve stems for manual airing of system. and alot of times there was a valve stem in trunk or under rear bumper to add air to system also

check the OD-II code first to see if anything else pops up and solve that first.
if your fan works, check your level of antifreeze, it might be low. if your added something like stop-leak in the system, you will need to flush the product out and fix the leak to get it normal again. test every sensors, the fan relay and control module until you find exactly what is bad and replace it.
if you do not find anything wrong, the computer is at fault.

The problem might be your Vats security system. This causes the car to either "not start" or "shut down" while running, or start for 5 seconds and then die. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shuting down while running, im sorry i have no quick fix...

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page......... They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks.

It take two people to find out if it has sparkplug fire. If it is not getting any fuel you may pour a small amount into throttle body and see if it will start if you have spark. If you turn it over trying to start it you should see the injectors squirting fuel down into it.

It's trans. time
