Vs ute on gas not firing

[Jaybax]

Hi my mates vs ute has gas and turns over but won't fire can anyone tell me what's the problem

Does it run on petrol? If so, then problem in LPG system - bad solenoid valve, stepper motor or LPG controller or wiring.

Na it doesn't start on fuel either mate. Just turns over but no fire. It's was running ok few days ago. He filled up with lpg then was running weird

If no cylinders are firing, then suspects are DFI module and crank angle sensor. Maybe the connector going into DFI module. A remote possibility is wiring harness. I have seen one where the LPG controller was spliced in to get RPM signal, then the solder failed, so no more spark.
