OK, I'll give you a crash course on the IP controls:
Oil in the areas pictured is normal. It flows in from the engine and back through the nose of the IP into the area behind the vacuum pump.
The square part you are indicating is the rack position sensor, it sends position information to the ECU to verify ECU commands. If this information is faulty, the ECU may keep moving the rack open wider and wider. The square thing stays put, the square "hoop" on the rack moves fore and aft over it.
The fuel rack is a rod with a larger round "nub" on it that sticks straight out of the back of the injection pump. You should be able to push if forward and have it spring back when you release pressure on it.
You can actually crank and start the car with the back off the pump but you have to take your finger and mover the rack forward a little to get fuel going. All the way to the rear is shut off or no fuel. You can manipulate the rack just like you would a throttle on a carburrated gas engine, revving it up as you push it forward.
NOTE! Sticking your finger into the back of the pump is VERY, VERY dangerous when cranking! There's a spinning lock and timing plate in there that can catch/break/remove fingers. You must actually look into the back of the pump to verify the position of the plate and make sure it won't get you as it turns.
You should be able to hold the rack forward about 6mm, crank the car and then adjust the engine speed manually by moving the rack back and forth. Again, for heaven's sake, be careful!
