I have a 2000 neon just got a engine put in now my car won’t start. forgot the code # but they say something about the pcm but the mechanic i got my work done at says its good. so where can i check to see my wires are broken or burnt out
What wires> Why would you think they are broken or burnt?
Frankly I think we are going to need to know what that exact code was. It should be in the format {P1234}
Whoever put the engine in should have made sure that the engine started and ran. Something is wrong, with them, if they didn’t.
