Welcome to the Diesel Stop
Your hard start problems are most likely caused by air in the fuel system. The 6.9 water seperator drain on the fire wall is one spot, and the return system on the injectors is another common trouble spot specially if the caps and lines are factory original (painted grey).
I would start there. What you need is an injector installation kit. just don't bother with the copper washers for now. Use your old caps/lines as a template. If you decide to use an electric pump, make sure it is regulated to no more than 6 PSI.
