I need some help with my logic please. I am trying to time the injector pump on my new 1976 240D. I need it to pass emmissions here in Denver so I'm putting a lot of time into the maintenance. I tried to follow the Richard Easley method on the Baylor.edu website which is straight forward but I never saw fuel coming out of the pump (pooling in the fitting). I was not sure the hand pump was pressurizing the pump enough so I tried to go one better and hook up my Heise gauge to the pump to check for pressure changes. The Heise is real sensitive--it will pick up a sneeze from 40 feet. I hooked up my air compressor line to the fuel line and pressurized it to about 30 pounds. The Heise was hooked to the pipe outlet to #1. I figured if I turned the engine I should be able to see some pressure when I reached the injection point. I never did. I had the linkage set to WOT but that made no difference either. Sorry to be so long-winded but according to my logic, this should work pretty slick and be real accurate. My poor brain is quite dizzy at this point so could someone enlighten me on why this isn't working?
