I have a 2005 quest van that cranks and but no start.it quit while driving it.

Do not rule out the crank sensor!!!

I suspect that your timing chain may have failed. Need to check compresson on both banks. If one side is higher than the other side that mis a indication that the chain has jumped on one side. It was likely the cause of the previous p0340 also.

poss fuse or relay inside ipdm but they are not replacable you must buy the whole piece.text fuses its located bythe ecm
