Make sure that the oil pump turns free you can use a screwdriver to turn it by hand

This is interesting to see and want to make sure I understand what caused the cam position sensor tone ring to stop rotating. Had the lifted off the motor and was no longer engaging with the camshaft (and no longer pumping oil)? Or can the gear on the oil pump driveshaft come loose?
I'm wondering if my timing marks on the crankshaft pulley are off or misaligned? I verified with the screw driver down the spark plug hole but there's such a huge range on the numbers where I can't feel the piston move any more. I can feel it start going back down about a quarter/half inch past the degree plate
I was wondering how you were going to do the alignment. From what I saw, the late model XJs have a tiny slot on the harmonic damper and then a single line on the block. Is that what you have on your XJ?Did you disconnect the battery after your initial alignment?
The videos I watched seem to suggest that there is a pretty wide range of camshaft position sensor body angles where the ECU can successfully sync the camshaft position sensor signal.
Is there a chance that your camshaft position sensor is damaged, or maybe there is something off with your crankshaft position sensor replacement?
I do have a tiny slot on the harmonic balancer but the plate with degrees have increments of 8° 6° 4° 2° 0. With notches in between the numbers.
I'm guessing something is fudged with the degree marks on the timing chain cover? Spoke to a buddy today and said all the timing chain covers from '84-'01 are identical so the numbers should correspond...
The 2000-01 has factory marks! The harmonic balancer spinning is a real possibility though.
I'm not following the timing marks comment. Are you saying the '00/'01 timing marks on the timing chain cover would have the 0 at a different spot than pre '00?
Have you or anyone ever heard of the harmonic balancer mark getting displaced? Ive never fumbled with one so I'm not sure how it's assembled (pressed vs welded)
..., or maybe there is something off with your crankshaft position sensor replacement?
