Normally it's either open or closed, still doesn't explain the air in the lines.
Suggests to me something isn't quite tight or there's a split. somewhere there's a source of air getting in, it would eventually bleed all the air out - once it's sucked it through the pump.
Did you see the XUD9 engine running with that pump before you did the conversion?
Also, the stop solenoid is the only electrical connection connected? Nothing else should be connected to it, that will eliminate any semi electronic advance issues.
A moments silence please, for our brothers in the NAD-zone.
