Most likley the instrument dimmer switch and that is part of the headlight switch, try wiggling it to get them on.

i know this sounds strange, but does the glove box have a lock on it? Like a keyhole of a door lock. If so, one of your keys should open it.

does it have the chip in the key!!???if so the problem is in the ignition switch! there are two small orange wires that break off! on the coloum!

Does it have a security system? If it does see if the security light is flashing. If it is you can reset most cars by turning the ignition to on and waiting for the security light to go off. Then it will start. This will happen again.

Read the plugs, remove them... they should all look dry and clean with a brown or whitish tint, if they are oily or wet looking or have carbon build up replace them, usually plugs or spark plug wires are the simplest cure unless you have major mechanical problems such as a worn engine or bad valves also you might check to see if there is water in the gas, put alcohol in the tank if you suspect water, rubbing alcohol works fine or any additive to remove water from your tank.

You must unbolt the front engine mount,then raise the engine with a small jack.

Splice the wires running from the keyswitch down the steering column under the dash and install a 100 amp resister from radioshack, this fools the computer and the car will start.Believe me I have been driving mine like that for 5 years.

If you know how to solder, you can try building up the "chip" area on the key and reinserting it. That's the only thing that controls the PASSLOCK theft system.

Measure the resistance from one of the contacts to the other with an ohmmeter, and you can get those keys from eBay. Once you get the car home, order one for a couple bucks, and get it cut at your local hardware store.

When you order the new key, they will ask you for the resistance measurement across the resistor embedded in the key, and send you one that matches.

If you'd rather order one from the dealer, they are still available last I checked, but were significantly more expensive than the eBay option.

If you had heat before, and not now, it sounds like you have air in the system. When the system is cold, open the radiator cap and check the level in the radiator. If it is low, fill it back up. Also, make sure you put the "tabs" in the radiator if you changed the coolant. There should be a decal that says the warranty would be void if you don't put them in. They are cheap at the dealer. Before you start it back up when it is cold, take the cap off and squeeze both hoses several times. you should see air come up and out the inlet.

It may help to jack the car up on the Pass side with the cap off let it run. putting a little 50/50 coolant in as it runs. Leave the heat on at high while you are doing this.

Hope this helps

The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

check the fuel filter might be clogging up not allowing gas trhu
