can you not turn the lpg over manualy by pressing the button on the control box or try holding the button in and rev to 2000. it could be the relay on the regulator not turning on.
 
Mine had a faulty ecu that stopped it switching, but as it was so old no one local to me could fix it, so i had a new one fitted, not cheap but it works. best thing to do would be contact a local lpg fitter and see what they can do, a reset may well just be what it needs.
 
Hi i had same problem on a multipoint Lpg system , it was the lpg filter solenoid switch only cost £27 for anew one fitted, P38 4.0se
 
A flat battery can cause this but so can a faulty lpg ecu. It should say on the ECU what make it is, my guess is its likely to be an OMVL system. You can buy a lead for these on fleabay and the software is a free download. But it will need to be sorted by a LPG fitter. If it just needs a reset when you get it home plug the software in and you can save the settings put in by the fitter. The if it goes agan you can reset it yourself (it will). If it needs a new ecu your looking at about £200
