be sure pump is cam lever isn't being held in by the cam turn engine until you get the best stroke on the pump lever . open bottom bleeder screw on injector pump, pump primer lever until fuel clear of air comes out,, sometimes removing the screw will help purge the air ,close screw ,open top repeat procedure. sometimes this takes a good deal of pumping because filters and injector pump have to be purged.once clear fuel comes out of bleeder screws make sure both are closed continue to pump primer a few more times to force any air left in the filters thru the return line. loosen any two injector lines at the injector ,put fuel shut off in run position ,put throttle in full position ,spin engine until fuel begins to leak from one of the lines tighten that line,spin again ,tighten the other line while spinning, it will probalibly start while tighting the line, let it get to full rpm then slow down to half for about a minute ,should be alright.
