Hi all
I'm a newbie so be gentle
I have a problem with the LPG system on my Chrysler 3.3 voyager and wondered if any one here can give some advice
Its a bigas sgis system
I bought the car in bits and the previous owner removed the LPG solenoids/ injectors to access the radiators problem I have is I have no clue what solenoid they go to as its a seqential system
I managed to plug them in and make it idle smooth after changing plugs and leads so decided to go for a cruise and now this is where it goes mad
the lights on my LPG gauge went out but stayed running on gas for around 15 miles then the gauge started beeping and the car switched back to petrol
Once I got home I tried running it on gas again and it idled fine
Now Ive just gone to it and the thing won't run on gas just drops onto 3 mayby 4 cylinders then beeps and switches back to petrol
So far I've re checked
I have LPG in tank
Vaporisor is hot
Coolant level is good
More new plug and leads
lambda sensor good

I'm really not sure what to do now and apologise for the length of my first post but I've been messing with cars for many many years and have quiet a collection but this thing has me stumped
