LPG won't start

[Steele]

GÂ’day,
I have a dual fuel (petrol/LPG) vehicle which up until today ran perfectly fine on LPG. Went for a drive today and the LPG just wonÂ’t start up.

Ran with no issues yesterday. The petrol still runs fine so I donÂ’t know whatÂ’s happening.

IÂ’m very new to working with cars so any help would be appreciated,
Thanks in advance,
Steele

First thing I would check is the solenoid to open the LPG valve. (or fuse or whatever the setup is you have there)
I haven't had an LPG vehicle for years, but this was always one of the go to sources when I had trouble with LPG not starting.

You should hear a very distinct click sound of the solenoid switching, when you are switching too LPG from petrol, or already on LPG when you hit the ign switch.

What Arthur said. Next, can you switch over when it's running on petrol?
