lpg problem, thankyou
« on: 23 March 2010, 17:12:26 »
hi all, just been to the other section and said hello to all members :)

i have a problem with the lpg on my car...

it switches to lpg for around 10secs (hot or cold), then switches back to petrol automatically...

i appreciate, it could be anything, but as there is only ONE garage around that deals with lpg faults (and its Vauxhall dealer), im trying to save a bit of cash if i can...

i have disconnected the fuses from the lpg- within the fuse box,and re-connected... but thats done nothing, it was working fine 2 days ago..

any help or tips, maybe things i can try or look for will be greatly recevied.. so tia  8-)

Is a "sequential injector" system  or a "single point" system ??

Is the water to the vapouriser getting nice and hot ??

When was the LPG filter last replaced ??

just the first things that spring to mind .....

im ok when it comes to petrol engines, but gas i have no idea..

all i know is the car ran on dual fuel when it was first made,
so its not a conversion by any previous owner...
i wouldnt know where to start  ::)

sc00bi,

Hello and welcome :y :y

Where are you living? It may be that someone is near enough to have a look for you. You can update your profile with this info :y

I'm assuming it's a 2.0 and, being "factory" dual fuel, probably a Coltek/Koltec (spelt both ways) Necam conversion.

It's worth searching on http://www.lpgforum.co.uk as there's a guy on there who's very knowledgeable about them... Pipj I think?

Could be any of a number of things... As said, Vaporiser temp/LPG pressure/blocked filter ;)

Vapourisers can fail through age - diaphragms harden/split, blockage in the gas side, or blockage in the water side..

But for sure, if the vaporiser ain't suppling enough gas .. it won't run on gas !!!

one other thing i notice, is when i switch it to gas, when the gas kicks in, it idles very poorly before switching back to petrol- if that helps at all??

thankyou all for your swift replies,
btw im in Southampton

hi again peeps, i have done some reading up on lpg..
i can confirm that water to the vapouriser is nice and hot...

i was thinking, shall i disconnect the gas distributor and clean it up, maybe clearing a blockage?? if i do, is it ok to disconnect all the connecting tubes without any safety worries..

just the first things that spring to mind .....

Disconnecting the distributor is fine... Use all the usual precautions, open space, no naked flames etc :y :y

hi all, just an update for you ...

on friday, i bought some carb cleaner and as it was raining- i never really had time to do much, so i disconnected 2 hoses from the distributer and blew some carb cleaner inside it, and cleaned out the 2 pipes i disconnected...

turned car over, no problems.. flicked to gas... and hey presto!!! i managed to drives around 1 mile to the petrol station and fill up the gas, i left the petrol station and drove about another mile... before it kicked back onto petrol and was now back to normal... gas fault...

So, today, i took out the distributer and cleaned as much as i could, i took the top off and blew carb cleaner down the inside, then put it back together...i took off the four hoses and cleaned them out- the liquid that came out was a little brown, but nothing to bad...

started car up.... flicked to gas, it cuts out after the 3 clicks... so i tried it a few times- nothing...

so, i took the top off the distributer, and noticed the plunger type screw was loose,and had a fair bit of play in each side... so i tightened it up and put it back together...

still nothin.... do you think my distributer has had it??

It's a problem with the gas not the existing car. Mine had the same thing last week and it turned out to be a knackered temp sensor inside the gas regulator. As it couldn't detect the water temp it couldn't switch to gas do as a safetyeasure flicks back to petrol.

My installer charged £40 fitted for a new regulator and all is well :)
