The link to the old posting is very helpful. Because I have removed the lpg from the wagon. Now I need to find the earth relay. I have seen one next to all the other relays under the bonnet. Maybe this one has something to do with the problem.
Is there a none return valve, for the fuel, at the fuel pump. I think its at or in the fuel tank setup.
A real wiring diagram would be helpful. To trace the injector wiring to lpg relay setup.
Why do you wanna know about the "not return" valve??!!!

There's a non return valve on the fuel line from tank to charcoal canister.
It's installed closer to the tank on that fuel line.
Highly unlikely that has anything to do with the problems you described.

What "earth relay" are referring to???!!!
Why do you need to find it??!!
