Calling CNGBiFuel !

Hello CNGBifuel.
In a recent thread you made the comment:
"regulator diaphragm can cause poor starting, but is fixed for £30 in parts".
My S60 factory fit Bi-Fuel is getting very hard to start from cold. The fact that the car starts on petrol made me ignore the possibility that the LPG system could have anything to do with it, however your above comment could well prove to be a "eureka" moment! Could you possibly tell me where I can get these £30 worth of parts which may be the solution to my problem?
Many Thanks.

The factory LPG always starts first on petrol as standard ... you need to investigate the petrol side of it .

If the diaphram goes it does make the engine hard to start on either fuel

Just as CNGBiFuel pointed out. So, as I asked initially does anyone know where I can buy the £30 worth of bits he mentions. I'm guessing it's a repair kit which include new diaphragm/s?

Not been on here for a while. Yes, sold on ebay, there are two types. I have used regulators about if you want the whole assy.

If the thing has gone you'll find cold starting awkward.

A manometer is going to be useful. Needs to measure babies-breath pressures. And no, a standard vacuum gauge won't do.

I had poor starting on petrol, summer and winter. After repairing my pressure regulator the problems were gone. The broken pressure regulator also caused an over-pressure in my cooling system. Apparently cng leaked int it.
The car runs great now.

Yes, they'll often squeal or whine when the diaphragm is on the way out, bu t not always. This causes poor starting and lumpy running at low revs on petrol because the gas leaks making the mixture very rich. And usually hte gas side won't work at all or very poorly.

Hadn't heard of gas goingot pressure the cooling system. Not sure how that could happen. No real route I can think of unless the coolant going htru' the regualtor has bad seals too. Can't see it but possible. Never come across it.

It's highly unlikely for the coolant to go to CNG as there is simply no way for it...
It's possible that coolant that was getting to the evaporator was not hot enough to get the gas evaporate as quickly as needed.

I tried to send you a pm, but I can't do that yet.

After cleaning the distributor it seems that I ca get my stepper back in completely. It just coming to the point where I can't push it inside with reasonable force. About 2mm above the surface of distributor.
What will happen if I connect my stepper to the car now? Will it go inside?
Need your advice
