Hi guys and gals,

im loving being the proud owner of a 1988 110 county v8. Bought it for my girlfriend nearly 2 years ago and never thought id like it so much ha ha. Unfortunatly the lpg system must have been fitted by a guy in his shed with no hope. Scotchlocks here there and everywhere and all the same colour wire(aaarrrgg) was running sweet then just stopped running on gas.

Bought a brand new dizzy new plugs new fuel pump rebuilt the twin su's new seals ect new sentech leads changed the oil and filter(i knew it wouldnt fix it) ive re done the wires to the switch the relay in the front and the fuel pump cut off.
the switch works and energizes the relay the solenoid in the tank clicks when you switch it and the gas flows and comes out of the pipes to the manifolds but it cuts out after about 3 seconds everytime. i have concerns about the vacuum or pressure switch but this just switches the negetive on the vapourizer so i earthed the solinoid on that and it does the same.

any help would be much appreciated what with the petrol prices and all.

cheers very much oli

Any idea what system it is?
There are a large number of things which I'd look at, but narrowing it down via the system might be a good approach....
The LPG controller may have a sense line for engine revs... if that's not ok, it may think you've stalled (before you have stalled) and cut the fuel... hence you stall....
If it's an injection petrol system... the "emulator injectors" could either be faulty, or their "pick-line" could be badly connected - hence it's still injecting petrol as well as LPG which might cause it to stall.
Any signs of ice on the vapouriser?
