Quite possibly - although there is another main solenoid in the engine bay and one on each of the twin tanks which shut off without an rpm pulse.electrokid wrote:Isn't that a safety feature ? No vacuum = no gas - stops gas spewing out if the engine isn't turning over.I think the inlet manifold vacuum moves a diaphragm and allows more LPG into the vaporiser.
Nope. The system should be continually self learning, so whatever fault condition developed 'coincidentally' with the visit to the LPG specialists, must therefore still exist. Been to another specialist today, feel like giving up on the fault finding myself - my credit card limit has just been increased so I'm in the state of mind just to throw money at the problem to make it go away. Even if it comes to a new system, at least then it will (should?) be more reliable, and have better spares availability in the future. I've had some fundemental problems with the system installation pointed out to me (some I knew about like the wiring quality) so maybe that's the best option?if I can just take it back to them to re-start the self learning program again I think my problems should be over.
(TPS is shared with the petrol ECU and that is working OK - I know the signal is reaching the gas ECU as the ability to rev is regained above 3k rpm).
