The security light is the reason that the starter is not turning over. The security light indicates a problem in the antitheft system. When this is triggered, the antitheft system turns the starter off to prevent the car from being stolen. The hard part is finding out which part is causing the antitheft to fail. Go to this link for info on how this system works along with some tricks to try, and ways to bypass this system entirely.
First thing I check for on a GM when it won't start, is the antitheft system. GM is notorious for these things failing. A dead give away is a light on the dash that says SECURITY or ANTITHEFT. If you see this light, go to this link. http://vatspasslockpasskeysecurityhelp.yolasite.com/ If no security light, the problem is gunna be in the ignition, the starter, or the neutral safety switch. You can always jump the terminals on the starter (key turned 2 clicks forward), if it turns over at the starter, the problem is in the ignition, or neutral switch.
Antitheft failure can cause a "no start" situation. Look for a light in the dash that says security or antitheft. If you see that light, go to this link
This happens due to a failed or failing antitheft system. When the system cant communicate properly, it will disable your starter or injectors and show the SECURITY light. Go to this link for info and ways to beat this system yourself.
This is an all too common problem on GM vehicles. The problem is in the design of the antitheft system. The system must keep a CONSTANT line of communication between the key's transponder or security chip, the ignition lock cylinder, and the Theft Deterrent Module which runs the system. If there is a break in this communication for even just a second, the antitheft gets activated, the security light comes on, and finally the vehicle gets immobilized by either the starter or the injectors being turned off. The hard part is finding which part is the culprit. Go to this link for info and some other options to fix this problem.
these cars have a antitheft system that will shut down fuel and crank. be sure to check to see if after the car ignition is on for 30 seconds and look to see if there is a security light on in the dash. if so then turn to crank if security light flashes your problem is that the chip in your key is not being transfered to the security module, so starter will not work. you will have to replace the pickup in the cylinder or bypass the security with proper resister
Does the starter make any noise or click when you turn the key to start? If it does not, chk. battery could be bad, and battery cables could be loose or corroded. If there good and clean and battery is good try tapping starter see if it will turn and start if it does or still clicks starter bad. It could be ignition switch if it does nothing at all, but if it clicks most likely its starter.
