How much fuel pressure did you register?

I show it as having a timing chain, and an internal balance shaft geared
to the camshaft. Maybe I am off by a couple of years.

If your spark does not come exactly when the cylinder has fuel
charge and compression, it will run roughy or not at all.

There is sensor in the timing chain cover, which is actuated by a magnet
attached
to the gear. It is not uncommon for that magnet to fall off, and a code
will be set.
It does not stop the engine from running, in my experience.
