I can?t switch my 2003 VY factory gas Commodore to LPG. I had it serviced and tuned recently after an idling problem developed and it was fine for four weeks, but now won?t switch over to LPG. What could the problem be?

It sounds like it’s not getting LPG when you attempt to switch over, and that could be something as simple as a power supply problem such as a lead that’s come away from its connection.
