I am struggling with my freshly rebuilt 88' idi 7.3l.... i have tried just about everything... i have not gotten it to run for more than 2 seconds... at first i had the the injection pump over advanced and it was billowing black smoke from the pipes while trying to get it started... So i went back to the factory setting of zero for the injection pump... The book i have showed me that to set up the timing for the pump, all i had to do was line up the 2 "y" markings together when the cam gear and crank gear were aligned properly and apparently this was tdc for #1 cylinder... now this was a bit perplexing because i never moved the oreintation of the ip from its body, so the markings on the body and pump are set correctly... but something is off... otherwise it would run... the motor has great compression... brank new valves, pistons, rings, bearings, starter, batteries, glow plugs, and glow plug controller... i have mixed the currently fresh diesel with a little under 20% 91 octane, and also mixed 1 oz. of 2 stroke per gallon in along with it, to try and get this puppy to fire... there is no air in the lines, great fuel pressure, and plenty of oil in the case... turns over great... just will not run... so currently with the ip timed in at zero degrees all i get is a lil' white smoke out of the passenger side manifold... very confusing... because with it over advanced, and all of the black smoke before; it almost ran... PLLLLLLEEEEEAAAAASSSSEEEE HELP! =) :doh:
