On the one page of troubleshooting notes I keep on my bike at all times I have it written (so it must be true)

That "Joel said":
There are only two sensors that were absolutely required for the bike to run (notice I didn't say "run well" I just said "run")
They would be the TPS and the crankshaft position sensor. If the BMS-K gets an "open circuit" reading to any other sensor it goes into "limp home" mode and just does the best it can do without input from that sensor. Unfortunately sometimes the sensors fail in a "believable state" such that the BMS-K thinks that the signal is valid which causes confusion.

I would "hot-wire" around the pump controller and unplug the pressure sensor
(not both at the same time ... try one then the other then both ... see what changes)
