I'm really not sure if anyone can help me with this, but no one can make it out here until Monday so I thought it would be worth a quick post.

So I am cranking and cranking and cranking and nothing. I've got a healthy spark, and recently replaced coil and air filter. Plugs look good. Cap and rotor and wires are alright. That leads me to believe the issue is no fuel. I have tried another propane bottle, same. I purged the pressure in the line and tried again, still nothing. This model I am pretty sure has the converter and regulator built into the same unit. I cannot seem to find a fuel filter. There was a bit of sticky black goo (looks like molasses) near the bottom of the outside of the diaphragm. I have not removed the diaphragm, just the two covers and solenoid on top of it (for cleaning). Used MAF sensor cleaner since it's plastic and rubber "safe".

Pressure is definitely making it TO the pressure regulator, as I got blasted pretty hard with propane when I depressed the spring at the hose that connects to the bottle. However, the large top hose coming out of the pressure regulator going to the carbeorator had a very small amount of pressure being pushed out of it at one time when I was checking for pressure, but now when I crank I am getting absolutely NOTHING out of it. Since there WAS a little bit (and I mean a very little bit) of pressure when I checked what was exiting that larger hose earlier and now there is NONE, I can only think that it is a pressure issue.

What bothers me is that if the diaphragm in the regulator was blown, wouldn't that mean I would have an excess of pressure? All I can think is that it is either a flow control signal that is not opening a solenoid, a faulting flow control solenoid not opening, or a safety valve detecting excessive pressure and closing. The manual that I have for this truck does NOT go into detail on the fuel system. Any advice is most appreciated.

Thanks for reading!
