I have a VS Commodore and it is dual fuel. I purchased it with a few minor mechanical issues, a few times it back-fired and stalled during short trips. Fifteen minutes into a thirty minute trip is blew the air-box apart and after getting it towed home and fixing the air-box it now will not start at all on either LPG or Petrol. It will turn over but nothing else. What could be the problem?

The back fire on LPG is usually due to cross firing ignition lads, do you have spark and fuel pressure on the petrol side and injection pulse? Depending no the gas system used, it should start on petrol and switch to gas after a pre set warm up time, it will not start on LPG. Also, check for codes and make sure no other vacuum lines have blown off.

Hi thank you for replying to my question.
As far as I can see there are no other broken or off things.I just wish something would jump out and let me see what the problem could be?
