Hi there ! My name is Andy and I would like to try and help you resolve your problem!
Sounds like something got hot and melted the ressin inside the ECM . Sounds like you may be looking at replacing the ECM . If it is cranking but not trying to fire at all , not even sputter , and you can't seem to connect to the ECM , then you are likely going to have to replace or try a test ecm if you know someone who has one !
Do you still need help ?
