I am getting at least 3 litres/minute when I do the fuel volume test at the supply line to the FD.
The car starts perfect and idles at 750rpm. When I press the accelerator it increases the rpm with good response, although a bit rough.
However when I put the vehicle in drive and try to move it , it moves but only just and cannot even drive over a small hill.
So essentially no power.
The fuel metering plate feels a bit hard when it is depressed. But this came of a working car, took it off myself, and the plunger piston is moving freely.
Please assist with your thoughts on how I can trouble shoot and resolve this problem.
Will appreciate all your help, I am on vacation and would like to at least drive this car for a few days.

So the engine revs with good response but is a bit rough? That could be a stuck / sticky injectors. Have you checked them?
As for the automatic transmission - could be a separate problem. Have you changed the transmission fluid and filter? Have you measured the primary pressure of the transmission (or any of the others?). I assume the transmission has been sitting for as long as the rest of the car (!)
