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.

Any code relating to the Ignition is probably relating to the Optispark. In my experience, stick with OEM. You can buy one from a dealer. Stay away from the cheap ones.

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.

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)
