    Hello Steve,
    I would expect that you have a single point mixer system fitted to this one & that your wiring fault could have damaged the injector emulators,which would stop any fuelling.What lpg system is fitted?Some systems allow you to start on lpg by switching the control switch from lpg to petrol & back to lpg again(where the green led should stay constant) & allow starting on lpg.If you are unable to do this you could start it on lpg by powering up the lpg solenoid until it starts & gets above the change over threshold ,where it should stay running on lpg (& you can stop the applied power).I take it that the wiring to the injectors has been cut to allow for the lpg wiring & if so,if the emulators are faulty you could bridge the wires across on the connector to the emulator(obviously after repairing the wiring).Sorry to go on for so long,especially as you only asked for a wiring diagram,but i thought the above info may help.
    I will try to get time tomorrow to find a wiring diagram & e mail it to you, regards,Andrew
