Could be the pump however hard starting is also a symptom of injector failure (high return rates) that could qualify for the 200Kmi/7 year Injector special policy ... http://www.thedieselpage.com/duramax...orwarranty.htm

(If you take it to the dealer I wouldn't tell them you bypassed the fuel filter)
