My grandma's 1994 e320 had the typical bad wiring harness which I replaced with a brand new one from MB. But not before the wires arched a couple times on the fuel rail, causing what I believe to be a hfm controller failure.
What I have is cylinder six has no ticking at the injector, I have pulled off the injector rail and swapped other injectors in # 6 slot but it will still not pulse, I realize the proper way to test is with a noid light but I don't have one. The other symptom is I have no a/c MB in Sioux falls, SD said that this could be controlled by the hfm being faulty.
2 questions:
#1 Is this what it sounds like to everyone else?
#2 Where can I find a cheap hfm I've looked on ebay
