To build fuel pressure remove the Fuel Pump Relay (FPR) and bridge sockets 7&8 (the FPR contains a timer which shuts off the pump if the engine is not running).

I did. I unplugged the EHA while it was running and watched the duty cycle, it started to drop slowly : 50, 40, 30, then stopped at around 20. I dont remember if thats lean or rich. (this was when it was running)
At the momment i cant get it to start at all, EHA plugged in or unplugged.
