Someone will correct me if I am wrong, but I believe that the PO 216 code is really bad news, and usually means it's time for a new injection pump, as for the other, if the pump is causing that many problems, it might have trigered the other code??? Not to sure on that second one though. I'm sure that someone else will chime in here!!
