the fuel filter would be the first place i would go, especially if it has not been replaced recently. it can cause slow priming of the fuel pump, resulting in hard starting. in addition, if your truck has never been tuned up, a set of spark plugs could make the world of difference - i believe on your particular truck it is recommended to change them at least every 100,000 M. good luck!
