hi can anyone help me??? ive got a landrover discovery 3.9 v8 which is gas converted. When its on petrol its fine but as soon as i switch to gas it cuts out can any one help as im trying to sell it and would like it to be running right with no faults thanks in advance mal.....
 
I have an old 4.2 on gas and while it has never let me down one day it did refuse to switch over to gas. Turned out that the inline fuse had blown and when I replaced it it was fine. Don`t expect it can be that easy but worth a look.
 
Friend of mine has had a problem with his lpg.

He starts up on petrol no probs changes to lpg after a short time fine but it seems to please itself when and where it cuts out , almost like fuel starvation.
Are these similar symptons to yours?

His short term fix was to leave it idling for anywhere from 5 to 20 mins prior to setting off ( determined by how cold it was ,weather wise that is ), he then had no problems for the rest of the drive.

However his car is still undergoing tests to try and source the fault after his previous garage could find none.
 
thanks . mine starts and runs brilliant on petrol but as soon as i switch to gas it cuts out.
 
What system are you running on? Air intake? or multi point injection? (Actual seperate injectors for each chamber)
If your on the Air intake like mine send me your email addy and i'll send you a PDF file with how to check your settings. Whilst i was doing my settings it could be something as simple as turning a screw to adjust the level of gas your engine is getting.

What's a discovery? :D
 
not really as i use it 2 go 2 and from work. Proberbly because i can afford 3 cars and a motorbike and not be big headed about it unlike some......
 
back to the subject in hand....... I'd check the operation of the 2 solenoid valves in the supply line. If its cutting out immediately you change over to gas, then chances are, no gas is reaching the manifold. Should be an electric solenoid valve where the supply line comes outta the tank and another just before the supply line goes into the regulator/reducer/vaporiser whatever you want to call it, in the engine bay. Check there is power going to them both when the changeover switch is on gas, if yes, next check they actualy work. Put a live supply from the battery direct to the + terminal of the solenoid coil - you should hear it click in. Usualy turns out to be a busted wire to the solenoid is the problem.
