did you check and see if you have pressure at the fuel rail? if you do, check the injectors and make sure they didnt get clogged up. it could be the timing, if it went you wont have no compression to turn it over. their timing chains, and can be a bitch to replace. i have a 98 gt and got a after market stereo in it. the theft lock is only for the factory radio. if you have it on when you replace the unit, the new and old one wont work. it will not stop your car from starting. i would start off with a compression check its simple easy and doesnt take long. if your good there. then try another computer or get yours reflashed.
