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

**another update**

Went down to Vauxhall to order the part mentioned above- £31 incl VAT.. so i have ordered one,just incase...

on my way home i popped into my local garage to see if they have any lpg knowledge, after a discussion with one of the mechanics in the know...

he said to me, it is probably the injectors,which will cost you up to £600, so therefor we wont book it in for work,as its not cost effective ... he also said to use a bottle on Winns injector cleaner and see if that clears the injectors...

im so lost now, i dont know where to start... but what id like to know is where does this temp sensor fit in regards to the vaporisor?? also, where abouts does the gas filter go?? does anybody have a diagram or picture maybe?

thankyou again for your help, i really dont know what to do anymore :-/

What utter 'dangle berries'! my entire install costs came to around that!

What ever system you must have, there must be a diagnostic lead....

Tunnie - you do not know what injectors his system has, nor do you know the type of LPG as regards to diagnostics - there are other options beyond Stag ECUs and Valtek 'injectors'

For Astra, but it seems Koltec is standard GM fitting for duel fuel cars, loads of threads on people getting ECU codes...

Worth checking the manual for how to get these

Do now 

Read out diagnostic system for Koltec EGI / GSI.
 
De EGI  LPG installation from Koltec has a self diagnostic-system which all disturbances will
be storages in its memory for a time.
When you have a problem whit the LPG installation, the first you have to do is read out this
memory.
This prevents expensive repairs, because the most auto mechanicals don’t have knowledge for
LPG installations.
Read out this memory is not difficult, and you don’t need expensive tools.
Behind de switch for choosing LPG / petrol is a grey wire whit a connector which is not
connected.
This wire has to be extended whit a other wire and connected whit the earth (chassis) of the
car.
Then you turn on the car key till all light bulbs in the dashboard go on all but don’t start the
engine.
The light bulb in the LPG/petrol switch goes flashing now.
This flashing is the giving the disturbances if there are.
 
Example1: 1x flashing, waiting a moment and then 2x flashing behind each other is code 12 =
no turning signal for the engine.
Note: This code is correct because we didn’t start the engine.(just at older types > 1995)
 
Example2: 4x flashing, waiting a moment and then 5x flashing behind each other is code 45 =
Gas mixture to rich.
Note: this code is coming often if the Vaporiser needs revision.
The diaphragms leaking and the Vaporiser/ pressure regulator don’t working well.
 
Every code will be given 3 times after each other before given a next code.
 
Codes which can be given:
Code 12 No turning signal for the engine (Vaporiser whitout temperature sensor)
(older type >1995)
Code 13 No Lambda sondesignal (lambdasonde or wiring is damaged)
Code 14 Temperature sensor signal to high.
(Vaporiser whit temperature sensor)(newer type 1995>)
Code 15 Temperature sensor signal to low.
(Vaporiser whit temperature sensor)(newer type 1995>)
Code 21 TPS-signal to high.(TPS = Throttle Position Sensor)
Code 22 TPS-signal to low.
Code 33 MAP-sensor signal to high.
Code 34 MAP-sensor signal to low.
Code 43 Divider/regulator don’t working.
Code 45 Gas mixture to rich.(light bulb in switch is flashing by driving the car)
 
When the gas mixture is to poor, the diagnose system gives no signal because it is thinking
the tank is (almost) empty.(light bulb in switch is flashing by driving the car)
If this is this is take a longer time, the system goes automatically to petrol run.
 
If the system is giving no disturbance code, and the light bulb in the switch doesn’t flash by
driving the car, the pressures don’t need to be checked.

guys, in your own opinions... what do you think i should do or where do i start, i dont have the cash to take it to an lpg specialist. my reg is R854 DAB - incase it comes in useful to anybody..

im thinking of doing the paperclip test


just tried the bulb flashing test... and the bulb doesnt flash at all.... strange, mind you i only had a thick piece of cable to connect to car chasis

Did you do this?

"Behind the switch for choosing LPG / petrol is a grey wire whit a connector which is not connected.

[sc00bi]

yes i did..

ill also mention i put some injector cleaner in to petrol tank and went for a drive- but it just cuts out when switched to gas(lpg light flashing)

[Andy H]

Injector cleaner poured into the petrol tank isn't going to flow through the gas injectors so why bother :-/

[sc00bi]

Two points come to mind.

1. Injector cleaner poured into the petrol tank isn't going to flow through the gas injectors so why bother :-/

2. The lack of any flashes from the gas system (and the fact it isn't working) would lead me to have another look at the fuses. It sounds to me as though there is no power to the gas system.

the guy at the garage told me to put this into fuel tank- shows he knows next to f**k all...and i did actually querie this, saying to him " if the car can run on lpg,then it will have seperate injectors ?"  to which he said they are shard between petrol/lpg

as for power to gas system- all fuses were checked yesterday- under steering wheel and next to battery, normal fuses and the fat fuses  8-)
