Ok i had kinda the same problem. if your father or bf is decent with mechanics ask him to check any see if there is any spark if not tell him to check the cranksensor to c if there is an current going to it, also when u go to start the car is there a (theft system light that comes on in the dash and flashes if so, turn the key fully as if you were going to start the car but dont crank it and leave it be for about 15-20mins or until the light stops flashing. then turn the key off and try start again. the thing is that when u install a stereo into one of these cars theres a anti theft system that stops fuel from going to the injectors. thats why when u install a aftermarket stereo u are supose to get eh harness so that it doesnt engage the ats(anti theft system). and if there is no current going to the crank sensor cut the wire long enough to hood an extra wire to it and then hook it up to ignition fuse in the fuse box(inside the car) this will send a a current to the crank sensor so when u turn the key on it will start. this is only a temperary fix. just gives u enough time to pick up the money to bring the car to the garage and get it checked correctly. anything else just ask.

Don't let your boyfriend install electronic equipment unless he knows what he's doing! the stereo could be the problem if it was istalled incorrectly! the positive or negative wires could be connected to the wrong wire or its shorting out your cars computer. replace all corroded connections.

I will venture to say that if the fluid level is on full then it is time for a filter change. You check the tranny fluid by setting the emergency brake, then sticking it in neutral and starting the car. Go see how it looks that way and let me know. I am not saying you didn't know how to check it. I am double checing with you. LOL Raz

Have it checked by a mechanic it may be a bad head gasket OR a leak you are not aware of.

You may see white smoke out of the tail pipe that smells sweet, this means bad head gasket.

expensive to fix.

Car starts run's 3 seconds shuts down


Your car is equipped with a system called PASSKEY standard on all GM cars and light trucks, try the following procedure to reset the system, the battery being dead will trigger the system.

PASSKEY LOCKOUT RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
