LR3 4.0l V6, cranking no start solved.

LR engine ecu does not trigger cam timing faults as described in diagnostic guides. After way too much time chasing electrical diagnosis, we disassembled the engine top end to find the cam timing was off. (Btw, this caused a no spark, no injector pulse issue, and didn't trigger any PCM fault codes). I suspect it shifted when one of the timing chain guides failed. Once retimed, the engine started and ran correctly.
