I'd like to see a higher KOEO
fuel pressure. It should be more like 40-50 psi
. Try the test again and cycle the key a few times to see if the fuel pressure goes up any higher. Also monitor the fuel pressure for 10 minutes after a KOEO
key cycle to see if the fuel pressure holds.
Fuel pressure should adjust so that the value on the scan tool stays close to 39 psi
at all times (pressure referenced to manifold vacuum). However, your other fuel pressure numbers suggest your engine vacuum might be low unless you're at a high elevation. This would seem to point to an unresolved vacuum leak. Double check the intake vacuum if you have a gauge.
voltage should be about 1 volt or just below at idle, so calibration doesn't seem that far off. However, the voltage seems to be moving around a little more than I would like. Is the idle unstable?
