Hi,
I have some issues with my fuel injection pump. As a frame-off restoration the engine was put aside 3 years ago and just recently I fired the engine up again
Here are some data:
1. Engine: L engine (2,2 liter)
2. Mileage: 85000 km - maybe 50000 miles
3. Tank has been cleaned, fresh fuel, new rubber hoses, new fuel filter. Brand new air filter. New engine oil, new coolant.
4. I have not messed with the fuel injection pump - nothing has been touched. Even the idle speed and max speed are in their original position from 3 years ago.
Observations:
1. Basically the engine fires right up and has a smooth and stable idle at estimated 700 rpm. There is no smoke
2. If I flip the throttle a bit with my hand, it responds fast and very well - to estimated 1500 rpm. However I "feel" that I need to flip through some more angular degrees to get response.
3. If I flip the throttle a bit more I sense some sort of hickups or misfiring and operation is not smooth anymore. It sort of feels as if the fuel injectors are starved of fuel for fractions of seconds (maybe air in the system)? I start to see smoke.
4. If I give full throttle the engine is def not able to reach max speed of approx 4500 rpm. It more feels like 3000 rpm and the engine feels more and more sluggish as I rotate the throttle lever towards its max position. Again it feels as if the injectors are starved of fuel. There is a lot of smoke (greyish - def not black or blue) and the smoke smells "wrong". 3 years ago I remember the smoke as being different in smell.
5. I dont have license plates on the car yet so I can basically not drive it in traffic yet, but I made some tests in the driveway: If I put the car in 1st gear and start driving (just releasing the clutch) everything is perfect. If I accelerate in 1st gear, the car picks up speed, but at 10-15 km/h the throttle becomes "unresponsive" and acceleration is not smooth but with the "hickups".
6. As from my memory I feel that the accelerator pedal has to be to be pushed much more as compared with 3 years ago.

At 0:07-0:09 you will see a "hickup" where the engine becomes a bit "confused "and does not accelerate smoothly.
At 0:15-onwards you will see that the engine is not able to pick up more speed even though I have not reached max throttle setting yet.
Questions:
1. Is there a chance that the injection pump has dried out and needs a lot of hard driving where the engine has to do some heavy work before everything settles to normal again? I understand that these tests that I made dont really pull a lot of fuel through the system.
2. Is there a chance that the govenor inside the pump is stuck somehow?
Does anyone have ideas, tips etc on how to solve my problem?
