2004 Chevrolet Colorado Repair Question
Swapped engine and now it wont start due to security problem...
try resetting the security system. turn key on for up to 10 minutes or until light goes out. then turn key off and try to see if vehicle will restart. if it does it's ok. if not you'll have to have a tech 2 put on it to see what is wrong. mostly dealers have tech 2's
