injection pump 9.3 2.2tide

Hello, as a “screw” nevertheless relatively inexperienced, I would like to ask for help. With my 9.3 ,2.2tid Bj. 99 the injection pump is defective according to fsh. The engine no longer starts ( starter turns ) As estimate was given to me ~ 1800€ plus installation. After I have now woken up from my coma.. Can someone give me tips where/how to get a cheaper solution. Oh yes, my 9.3er has up to now 324 000 km on his slender cross. Harry
