Just wanted to give another update.

Still facing the same problem. I've done a few new things since last time with no results.

First I took apart the injector wiring loom since that got damaged when I first re-installed the upper intake. I redid all of the connections and used a multi meter to check continuity across all plugs, everything here was good.

Next, I bought a set of plug wires. I got ones that are long enough for me to switch coils and see if it would fire any better, it didn't. It didn't seem to have any affect no matter where I connected the wires, the engine continued to turn over the same way it did in the video I put in my first post.

And finally, I put a new crank position sensor in. Of course this also had no effect.
