I am wondering if there are any great mechanics/auto electricians or forums to assist with a problem I have.

I have a 2000 X Discovery 2 V8 LPG GS model

and a 1998 S Discovery 2 V8 LPG GS model

both with approx 130k miles

both with seized engines

engine is the 4 litre Thor v8, not the Gems v8

Engines were removed from from both cars

I thin bought an Engine from a Land Rover breakers, although it was not warranted.

I decided to get the older Discovery rebuilt, as it had a better spec, was quite tidy and had some extra features

The 'new' second hand engine was put into the older Discovery. It then passed it's MOT, and the LPG switches over seamlessly.

The problem is, there is no power delivered to the car. It will struggle to do 8 mph

the garage that are doing the job are at their wits end, and want to abandon the job, as their is nothing more they can do. The car has been to the auto electrician and they can not solve the problem.

The car revs, a little unevenly. there is spark to all 8 spark plugs, as I added 1 coil pack from the other car.

The Land Rover Centre Huddersfield put the car on their diagnostic. It mentioned a an immobiliser fault and a throttle idle valve fault.

The garage doing the job also added the crank positioning switch from the spare car, incase it was that.

I know no history of either Discovery, nor do I know the history of the engine.

The fault is said by the garage to be electrical. I am not mechanically minded as such, so I cannot tell on what they base that assumption on, but they are a good garage and I do trust them, so as a layman, I don't doubt their word.

The engine is very, very slow to rev. It does not transfer any power to the car.

Could it be timing, or an earth?

I don't know what to do, and neither do the garage, the auto electrician or the land rover centre.

I would be very grateful for any advice on what to check, or someone to get advice from, or a garage that can do the job.

i need the car running.

I have an identical car to take the spare parts from.

As for budget, i am pretty much skint...
