Dear Charlee1961,

Have you had your system completely checked, made sure that all relevant gas pressure is within normal range, and that the engine has correctly been timed and adjusted in order to compensate for the new fuel?

Have all of the plumbing, the guages and the fuel management and delivery system double checked too. I will need to know if the engine is cutting out on idle, or when you are switching the engine over to use LPG. Will also need to know what conventional fuel this vehicle was using.

I hope to hear from you in the near future, but I hope my simple checks do work things out for you.

Yours sincerely

IF you are on lpg then check that the gas regulator for icing up and stopping the liquid LPG from turning to gas. If it cuts out on petrol check that there is not a problem with the petrol shut off solenoid . Check the LPG cut off solenoid . I suspect a loose connection or wires to either or both or faulty units

Dual fuel landrover discovery 1997 runs on gas but not fuel

Hi pal, I have been having similar problems with my gas conversion. I have a petrol mercedes sprinter that when it decides to run it runs fantastic, no complaints. However after spending the best part of £800 to solve the problem in several different garages things just seem to be getting worse. Every mechanic that I have spoken to has given me a different cause to the problem and 'fixed it' only for me to find that as soon as I get it home the problem reappears.If I keep it on petrol it runs fine, but if I change over to gas after a warm up period it makes a noise like it is trying to '**** ' the gas through but then the engine starts to sound like (you may remember this sound from childhood!) a lollypop stick clicking against your bike spokes. After a very short period the engine goes in to idle and finally cuts out. I am unable to turn the gas back onto petrol while this is happening.Occasionally if I stop the Sprinter and switch off the engine while on gas when I turn the ignition on again it can , when it feels like it, run absolutely fine again. The lollypop stick noise goes away and its great. Mechanics specialising in Sprinters have so called run diagnostics and have found no problem but they felt the need to change the wiring loom to solve the problem, that didnt work. Auto electricans have looked at it and have said it's possible there could be a dodgy wire somewhere! It has been back to the conversion garage and they say everything is working as it should, it must be a petrol problem. I am tearing my hair out over it. If you have since solved the problem I would be ever so grateful if you could let me know how it was solved. Thanks Helen from St Helens England.

On lpg vehicle backfires and blows intake pipe to pieces

Hi LPG is very dependent apon plugs and lead quality, the first thing to do is replace them both with new, it may very well cure the fault.
