SOURCE: 99 chevy cavalier theft system light on steady, car wont crank.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!

SOURCE: 2002 Chevy Avalanche. Truck will not

Do a bench test on the starter. Remove starter, hook up a ground cable to starter, and positive to two prongs on starter and it should spin. You can do this in vechile too but not suggested due to risk of injury. If it doesn't spin, probally a solenoid or the starter it self. Unlikely but possible.

99 explorer alarm disables. Motor dies


Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

Why wont my alarm reset in my 1998 chevy blazer the security system is killing the fuel and i cant get it to run it starts and dies imeaditly


I don't think the anti-theft is the problem.
On GM vehicles, the anti-theft system will not allow the engine to crank, or get fuel or spark. If it cranks, you have a different problem.

2002 chevy monte carlo won't start


this vehicle is equipped with a factory anti theft system if when you try to start the engine and the anti theft light is on then the starter won't start even if your check engine light is not on you would have to scan the body module to pin point the problem to see if it's the anti theft system or the starter, go to a auto parts store like auto zone or pep boys or western auto these store offer free scanning to there customers. if this information has been helpful please let use know good luck
