Glad to hear you got it sorted in the end.
Congratulations on finding the problem......think I mentioned way back in my other post on this to check the lpg air supply/leakage....I'd be pissed at my mechanic as well. And you say he does lpg as well, hmmm. I'd be publishing his name everywhere I could. Sometimes faults can take a while but that was a simple fault to find. Enjoy having your wheels back.
Hi Qldchris, i worked out what im gonna do.Im gonna get another Lpg installer to install the Lock Off Valve ( i can do it in 10 minutes,but im getting to that part ) and get a receipt saying unit is installed and whole system is ok, then take it back to the so called Mechanic,demand for refund,and if no refund,then to Fair Tradings,and im also gonna make some cardboard plakards saying " warning,dont get ripped off by ####### mechanical and Lpg,quick to take your money and faults still not fixed",or something along the lines of that !, and stick them on the car, free advertising lol.....
No one is gonna take Muzz for a free ride.
I feel your angst and anger but be cautious, you may have noticed that there have been may people on here trying to help but I can't recall anyone pointing directly to the fault.
Intermittent faults can be very very time and money consuming and anyone in business is keen to keep their clients happy so I would want to see what he is prepared to do for you first and be reasonable.
If you aren't careful you could find yourself in a legal dilemna for slander / libel and no one here wants to see you end up in that situation either
Good Luck & keep cool
Hi Cookie, funny thing was, it wasnt intermittent, it was all the time when the engine was cold or 15 minutes after turning engine off.I worked out that the reason it would start straight up again within the 15 minutes is that the engine was still pressurised with Lpg, but after that 15 minutes it would loos its pressure and hence cranking over on both fuels causing it too flood.
As for the Mechanic, nu im not going to go to that extream,i'll just show him the receipts from the other lpg installer and if he wont refund at least 50% of labour cost ( which i think is fair ),then i'll just take it to Consumer Affairs and leave it at that !..
Muz, once the part is installed and the jack is running as it should, wait a few days before going to your original mechanic just to ensure the switch IS/WAS the problem.
Go in polite and calm. You'll have a better chance at a partial refund if he gives you one.
Has he charged you labour along with the parts or just parts only. He may only refund part of the labour.
Either way, at least you know all the electronic side of the motor is spot on now.
Ive also been told when a Lpg car back fires it can wreck the Catalitic converter and sending false signals to the 02 sensor,( when the converter crapped out about 5 months ago,it was back firing for about 7 lkm before i got it to the mechanics ) so im going to replace that 1st and see what happenes.If still the same, then off to the Auto Electric guy.
Unplug the power wire going to the first gas solenoid on the firewall and if it starts cold then the problem is the switch is sending power there on start up when it shouldn't be. Break it down, you removed the gas and the wiring it ran fine, you put it back in it played up. Leave the cat convertor for now and focus on the electrical issue. There must be a timer in the system that tells the car to switch to gas after a warm up and it must be either wired wrong or failed. If unplugging the power wire works, take it to a good gas fitter and ask them to rectify it. The problem is isolated to the gas electrical circuit.
