I have a 2000 dodge neon 4-dr se, the timing belt went out and bent the valves. I replaced it with a 2001 head and went to start and it wouldn't. I unplugged the cam sensor and it starts, of course being disconnected, the engine light turns on. But why does it start with the cam sensor disconnected? ANY IDEAS?????

 

Did you put the wrong head on like an r/t head
