Just wanted to give an update on this as I did end up fixing the LR and she is back on the road again.
For me the cam gear that runs the hpfps was out of timing by almost 180 degrees. I ended up removing the vacuum pump and front cover to expose the chains. I then pulled the AUX chain tensioner back removed the guide on the passenger side. I then was able to put a crow bar wrapped with a sock on the ended to protect the cam gear and put it in the slot of the cam gear and rotated that while taking tension off the chain with the tensioner.
Made sure the fomoco writing was on the top side (see attached photos) and was able to use the cam gear alignment tool and see it was in alignment. Put the timing cover back on along with pulley and crank bolt vacuum pump etc and she started right up and is running great. There was no need for new hpfps or vacuum pump.
There is a ton of information about the chain and lining up the mark on the crankshaft along with the cam gear mark. This is irrelevant for this situation. That is only important if you are doing a full chain replacement with the motor pulled or completely stripped. The cam gear is a 1:1 ratio so as long as the cam gear is in the correct position it will be just fine. This confused me a ton at first but don’t over think it.
Hope this helps someone down the road. It’s honestly not a bad job. Easier than doing the chains which have already been done so I can compare the two.
@Tapps33 gets a big shot out from me as he helped me with understanding the chain ratio and that I was over thinking the whole issue.
