Pulling Injectors on a 2250

Well Yes and No.
NO, if the piston is not at or near TDC then there is nothing to stop valve travel and the valve will not "hang up" and allow you to remove the collets and then release the spring to change the v/g seal...
...unless the seals have enough resistance to hold the valve just enough to remove the collets, then when the seal is removed and the valve drops into the cylinder...then, YES, you're fucked! No ther way to put it.
