so to clarify its a dual fuel system
but it won't start on LPG when its hot?
Or does it not start on either fuel when hot?
To be honest hot starting on many LPG system is poor and its common practice to always start up on petrol and then switch over to LPG once the engine is running
OK if the issues only occur on LPG then I'd 1st say to check the tank regulator by measuring the gas pressure at the gas injectors
and also check the state of the electrical connections to the LPG controller thats running the injectors as often with aftermarrket systems the control ECU can be a bit flakey
if you can tell me the make of the sytem then this would help
OK in that case I'd suggest to consider replacing the spark plugs
especially if any fail this checklist
and the LPG usage will be worse than petrol as its not as efficient, however the cost saving is made as teh fuel is about 2/3rds of the cost of petrol
do you still need help?
