2000 Durango p0320 code
 

2000 Durango. Wouldn't start. Had a code for a cam position sensor. New cam and crank position sensors, plugs, coils. Still won't start but now have a p0320 code. Any ideas?

Durango 4,7, 5,2 or 5,9?

I'd have to guess 4.7 being that he said coils (plural). I'd make sure the cams are actually turning

still no start
 

It is a 4.7 , what is the best way to check the cams?

Pull the valve cover or timing cover I'd guess. I don't have much experience with the 4.7

Now it back fires still no turn over
