VY II Storm Ute Duel Fuel (LPG) *Problems* Can anybody be of any assistance?

[JGB90]

Hi, I currently have a VY II storm ute which is running a duel fuel setup. The ute is running perfectly on ULP though when i try to change over to LPG the car just stalls. I also cannot start the car on LPG which i usually used to be able to to. Im not sure whether anybody can help me with this, to try to narrow down what the problem could be. Without having much experience i seem to think its an electrical problem as it seems to cut everything out including starter motor which will not kick. Has anyone else come across this problem, opinions would be greatly appreciated.

Thanks.

You need to have a good spark for gas, so try need plugs and leads. If it is an aftermarket system it may need a tune up by a gas mechanic.

Find out what type of system it is first - ie. air valve or injected style? brand name? then contact someone who has knowledge in those systems. they should be able to help you out.

cheers.

When was the last time you serviced the gas system aka gas filter and the like?? I'd be saying its maybe blocked as well as your electrical issue

Did you check the little rubber vacuum elbow at the bottom of the throttle body?
Sometimes that comes loose and falls off, just superglue it back on if it has fallen off

Check the spark plugs, mine started doing this when I changed them, you need specific LPG ones it seems
