Check your fuel filter. Does it throw any codes

 

Having the codes read is the best place to start. If you don't have code reader, places like Auto Zone will read them for you. Next, you need to check your fuel pressure. Lack of fuel can cause hard start and ruin the injector pump. These truck need a minimum of a fuel pressure gauge.
