Hi,

I have an issue with my ute that has emerged over the winter months. Ive got an XG with duel fuel. The problem is that it will not start on gas at all. It will wind over and over but wont fire. WHen its switched to petrol in will wind for a while and eventually fire and run then, if I turn the car off, switch back to gas it will fire up and run straight away. It never used to really do this.

Is this a sign of a weak spark?

Thanks

Might be the injectors?
