the security light on? will it crank at all? did it start and stall?
security learn is key to on for 10 minutes, off for 10 seconds, 3 times, 4 th time turn the key to to run and then crank it, should crank and fire up.
if you have a scanner, clear the code, then do the learn.
its a reptile tune, its set up like a zzp or intense pcm with a 10 second key to on then back off, next turn it will crank and run. they do this cause chances are its not the same osid # number, this saves you 30 minutes of your life.
in the bin is a area to change the security settings.
