GM had a nasty time with security interlock during this period. I had a Colorado 2008 same issue. I found a company that made a chip that could be placed in the box next to the passenger footwell that basically told the switch to ignore the Key signal and things got better. UNFORTUNATELY I do not remember the name of the company but they are gonna pop up if you google GM Passlock .....nevermind I did it myself. ; NEWROCKIES, INC makes a gizmo that disables the system. it is 279 bucks now... twice what I paid 6 years ago, but it has a money back guarantee.... nothing to lose...good luck
Check to be sure there is a ground cable to body section of car , battery to body ,also body to engine ..battery to engine also ... sounds simple but it is very important....

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.

i have a 1997 pontiac grand am and it did the same thing when you go to start car and it won't start after 3 trys you have to turn the key to the on postion and let it set for 11 min no more then 11 min then turn it off and count to 30 then it should start. there is no way to go around this wiring .i have asked everybody also if you disconect the battery for a while and hook it back up that might reset the computer and that will work that is what fixed mine for now its been 6 months and hasn't done i sense

If the anti-theft light is flashing then it is in theft mode. If this is the case turn the key on and wait 1 hour then cycle the key to see if it starts if it does you have a anti-theft problem see dealer. sorry.
