Crank No Start Nissan Forklift K21

Hello everyone,

I'm having issues with my Nissan Forklift MPL01A20LV. I changed out my LPG Injector, Regulator, and Valve Assembly with all OEM. I'm still getting high fuel pressure and I am stuck on what or where to look next. I'm not sure if this may be a defective regulator that I was sent out so that may be my new direction I go in warrantying out this one I bought. Any and all help will be greatly appreciated.

Back story on the forklift : it was used the day before and it was operating without any hiccups, the very next day I had a crank/no start condition with it.

On the top of the converter you will see approx 19 mm. Bolt head with a Phillips head slot in it make sure you bleed the gas out of the line before you undo it. Also there is a o ring on it don't loose it as it will leak gas when you put it back try to get a gauge that goes to apply 40 to 50 psi just in case the converter is bad the pressure could spike see if you can find an lpg gauge you might have to adapt a fitting to go into the thread of the converter if you can't than l have used a hyd gauge but it won't last long. Get back to me.

Hey Scott, is there a specific gauge to use to check LPG pressure? I'll get it checked out today if one of the auto stores have it in stock. If it's higher pressure than that I'm assuming it's that pressure converter/vaporizer?
