LT1 won't start..HELP!!!
LT1 won't start..HELP!!! I parked my trans am in my driveway a few days ago and didnt start it for 3 days, when I went to go start it, it wouldn't fire. I ran a scan on it and i got this code "Ignition System Problem elec spark timing (EST) open circuit" I checked all my plugs and everything is plugged in. I am not sure what else I can do.
There's a little wire that plugs into the top of the Opti. Make sure that is securely plugged in. I know mine wasn't when I replaced it and ti would sit there and crank all day.

Verdad Gallardo I would question the warranty on your Opti and go from there. I don't know what else could be holding it up. Are you getting fuel?
List of mods?
edit- did you reset the battery? (to reset the code)
