After you get the enrichment pump running, make sure your manual enrichment valve is closed. Turn ignition key on and the pump should run at all times keeping about 5 lbs of pressure on the enrichment system. The fuel line inlets for the enrighment system has filter screens in them if fuel still not getting through you may have to remove enrichment solenoids and blow air in to push trash out. Beware there are o-rings in the carb at the solinoid tip, if you loose one the enrichment pump will push the fuel past the solinoid and cause flooding. Also make sure your relief vakve is keeping about 5 lbs of pressure on the enrichment fuel lines, it maybe clogged letting pressure bypass. On a cold start you should see about 4 volts going to the solinoids while starting. Make sure the solinoids are opening to allow fuel into carb. The pump draws from carb #6 then to each solinoid then a pressure relief, teed off that is a line going to the manual enrichment valve that feeds into the lower fuel pump. The manual valve can be used for cold start when the enrichment system fails but will only work if the enrichment electrical pump is working, once engine starts the manual valve must be closed. For the engine to fully function properly the enrichment system needs to function as it aids in run funtions as well as cold start as the ecm dictates.
