I am diagnosing a low fuel pressure from my first engine start. The max fuel pressure was in the range of 10-12psi, with boost pump or with the engine running without boost pump. The engine is IO360 and I was told the nominal pressure is 27psi. The avionics is all Dynon. I have the new Kalico sensor after the AD.
As part of the diagnosis, I fed compressed air and measured the true pressure using the differential pressure tester. At 30 psi, the fuel pressure level never moved past 12 psi.
Question: is there a way to calibrate the fuel pressure using the Dynon EMS calibration? Or is the sensor kaput?
Thanks
Edit: the engine start went okay. The engine response was nominal and thus I don't think fuel flow was the issue. Fuel flow test yielded 3x the required for this engine
