I initially started a R&R of all fuel lines and o-rings, to include o-rings and crush washer in the IP on my 96 E300D. I did manage to get her dry from fuel leakage. In my continued efforts to solve a mis on one cylinder, I further removed the fuel delivery valve in the IP for that cylinder.(mistake) I'm unable to get the engine to restart. I regret to admit defeat, but believe that I may need to remove the pump and send for calibration. How much should I expect to spend for calibrating the pump and where might be the best for this Bosh pump 0 400 196 002
