Ford Falcon Engine Problems

Check the system to see which LPG company developed the system for Ford and take it to them for checking. If you are unsure which company made it contact Mercer Industries (03 8788 1000).

It’s most likely the crank angle sensor, which is on the crankshaft. Have a mechanic check it.

You could, but it’s a lot of work and I wouldn’t recommend it. If you really want to do it the best way might be to buy a wrecked petrol-engined Falcon and swap over the engine and fuel system. You could also extend your range by fitting a second LPG tank.

It’s most likely a problem with the engine management system; it could be a faulty connection, dodgey sensor, or a problem with the ECU.

It won’t be the distributor or the spark plugs. If it happens when you turn the key to the start position to crank the engine it could be the starter solenoid.

The Falcon engine has a cam timing chain, so that's not your problem. If the auxiliary drive belt looks like it might be slipping, it could mean that it's worn, so have it changed. It won't cost you much to have it done. The oil leak could be from the head gasket, it might be sealing correctly. A head gasket change would cost you up to $1000.

Ford's official fuel consumption was 11.3L/100km combined, now that's a blend of city type driving and country driving.

Given that, if you're driving mostly in the city I would expect you to get a little more than 11.3L/100km, so maybe it's not too far from what you should be getting.

It shouldn't be pinging on 91-octane fuel, and I'm guessing the engine is carboned-up.

I would give it a solid blast down the highway and see if you can blow the carbon out. You could also try an engine cleaner in the fuel.

Great to have a real-world explanation from an LPG veteran.

I suggest you telephone some wrecking yards — which are called car dismantlers these days — to see what's around. If any CarsGuide readers can help I will put them in touch. The code for the unit is 3R23-12A650-HH ABU-214.
