if the car runs OK on pettrol then I'd agree that the issue is likely to be an LPG injector

, if the injectors are working you can hear them click - its difficult to hear them with background noise so use a long screwdriver like a stethoscope, placing the handle end in your ear and the metal tip against the body of the injector whilst your assistant turns the engine over.

If you can't hear anything check the ECU ( LPG unit) power is present by measuring voltage at the fusebox and on its relay socket
