Don't concern yourself with codes or how it runs, until you get an oxygen sensor in there. The LH2.4 system will run a default rich map without it participating in the closed loop servo. The codes telling you that won't set immediately, and you need to clear the memory by removing power (lift fuse 6) to start over.

Guessing your pressure gauge is off, but don't know. Just more likely than two FPRs with bad springs.

The whole purpose of the system portion of the fuel injection relay is to provide power to the FI system after the key is turned off. This is to facilitate cleaning of the hot wire. Not weird, but normal.

The AC clutch wire seems to be poorly supported, because it is a common victim of vibration. Just turn the AC off until you get it fixed.

Today a man knocked on my door and asked for a small donation towards the local swimming pool, so I gave him a glass of water.
