Injection Pump Help

Hi All..Think I may have made a bit of a cock-up..
I had to remove the IP on my 200tdi and did not lock the pump with the bold on the side..
The old girl now smokes like a trooper and has no power..How can I reset up the pump ?
Cheers

Im so curious to see what people say about this because I did the same thing...Only I decided it was time to change the timing belt and did not lock in the pin.....Not sure what to do

It's simple just line up the hole in the pump drive flange slide a 9 mm drill bit in ! Make sure it's in the hole properly ! The location of the hole is at 12o clock ! Line up crankshaft and camshaft put belt on tension up and turn engine over a full turn ! Just make sure you have the marks all lined up !!
