I have a JetCat P70 that I have not started in a number of months. It is propane start and the last time I ran it, it started with no issues. I checked the glow plug which looks fine. I then disconnected the coupler after the gas valve and there is no propane flowing during the startup sequence. How do I test the valve and is there some
other troubleshooting or setup process I am missing. A new valve is $70+ so I dont want to purchase if that is not the issue. TIA.

Do you hear clicking from each of the valves? They normally click pulsate.

Remove and insert the gas valve plug in & out of the ecu a couple times , possible contact issue
In fact it wouldn't hurt to wiggle all the plugs to ensure good contact in the ecu

You can switch it with the fuel valve to prove it out

Had an issue with Wren solenoids on an engine that had been out of service for a while, both solenoids not working.
Found I had to resolder both connections at the solenoid end, not sure why, it wasn't crash damage. All fixed now.

You can take the valve and plug it in to a servo driver to test. It might just be stuck. Can heat the valve with a mono coat iron while exercising it with the driver while blowing air through the line. Dan
