I am changing the injector pump on my D4 and when I pulled the pump off that I am putting into it I pulled the shaft out without realizing it, now I dont know if it is 180 out or if I may have knocked the timing off when I put the shaft back in, how can I make sure that the pump is timed correctly before I put it back on the motor? Any help would be great. Thank you.
 
Just pay attention to the offset tang on the pump camshaft and the auxilliary drive shaft. Assembled correctly sets the timing.
