sounds like you might have the wrong pin. is it common rail, or normal injection? the pins are different on the two engines. the common rail pin has a pimple on the end, it will fit in all holes on flywheel, but on one it goes deeper to accomadate the pimple, can be a bit awkward to find the right hole. the normal injection engine has a straight pin and will fit in in only one hole.
hope this helps.
