Trying to figure out what I did wrong.... I used this video as a basis: I removed the injector rocker, unplugged the injector carefully, the removed the injector hold down bolt. Rocked the injector back and forth with a light rope under it to lift until it came out. Removed the old seals. Used some vaseline as suggested on the video and coated the new o rings (but not the copper rings and snap ring). Put it all back together. To Adjust the injector, I used to instructions on another site. Basically intake lobe of cam pointing at the hole on the rocker arm. Tighten injector until it stops with 6mm allen wrench, back off 180 degrees and then tighten the locking nut. I thought perhaps I had gotten some air in the system so I cranked it pretty hard (with breaks to protect the starter). But I did not purge the fuel system, perhaps that is the next thing to do (although turned the key on and off about 10 times before trying to start as I seem to recall that is the process for after removing the tandem pump). I clearly missed something.. Anyone have any suggestions where this could have gone wrong?
