Hi. Can anyone tell me the signs of a failing injection pump? Can changing all injectors make an injection pump fail quicker? I just changed all of my injectors. Somebody at a garage told me this and I found it pretty strange,I figured it would help if anything... Thanks in advance Mike. 1989 GMC Jimmy 6.2L 4x4,1969 Camaro Z/28 502 C.I. B.B.C.
