Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Long time member here, have not been on forums in many years. My 2003 C4S Cab manual won't start. Has had regular service. The IMS was done in 2016. Have only driven a couple thousand miles the past few years. Now the engine won't turn over. I don't hear any metal or anything. The symptoms sounded like a crankshaft position sensors, but I am getting codes P0344 and P0349, which are camshaft position sensors. I am going to do a compression test after lunch and if compression is good I will replace those two sensors. According to a few things it could also be the camshaft rotor wheel is damaged. I put the boroscope in the engine and see a little bore scoring but not much. As of right now the car will not start at all.

Well, first things first. Got to get the "engine to turn over" before it can start. What happens when you turn the key...? Battery in good shape...?

POST 3Original post

Describe "won't start". Does it turn over? How old is the battery? Will the motor turn over at the crankshaft? Does the starter motor spin?

POST 4Original post

To most, this refers to the engine NOT cranking. Oh, so you really have a cranking engine, but a no-start condition. Typically, one begins by checking all fuses. Read here under No-Start; https://www.systemsc.com/diagnostic.htm

Yes, you need a $60k 4.0L upgrade.

POST 6Original post

Who does your work locally? I live in Miami as well and Hernan at Weissach is legit, if you can't figure it out here... reach out and see if he can help you.

POST 7Original post

Along with the suggestions above, I would also check on the fuel system.

This is a source reference. Confirm exact model applicability in the original material.
