My Mitsubishi Express LPG was running fine, re-fuelled and went to switch back over and it will not work. Running fine on fuel. After a day I got it to idle on LPG but will not rev, it just stops every time I accelerate.

My first thought is the LPG(propane) tank is empty or very close to it. If this is not the case, the regulator would be the next thing to check. Next check the wiring at the switch to make sure it isn’t trying to run on both which would want to flood the system. Check the wiring harness to make sure it is turning on the LPG valve.
