Yes. The motor was already lubricated and the oil pump was packed with petroleum jelly as per the instructions in my Haynes manual.

Following the Haynes motor manual instructions, I installed the synchronizer with the alignment tool (plastic cap that sits where the sensor goes) and the number 1 piston at TDC.

Just thought I should mention that all these problems persisted with both stock and replacement parts. I started with replacing the camshaft position sensor since my OBD2 reader said that was the problem. I then moved onto replacing the entire synchronizer with a fresh camshaft position sensor. I finally replaced the oil pump, pressure sensor, and sending unit. There have been no noticeable improvements.
