Re: hard starting
sounds like the fuel pump... try turning the key "ON," but not starting it for about 10 seconds. Then turn it over and see if it doesn't start right up.

Re: hard starting
Could be a clogged fuel filter not letting the fuel through fast enogh on startup after the fuel pressure has drained off.

Yeah, and for the $6 for a new fuel filter, I'd go ahead and change it

Had the same problem try to change the fuel filter frist. If that does not work then check to see if you have a check motor light on, if so it is the mass air flow sencer. But if not when you start up your truck and if it makes a loude ring or busing sound all the time it is the fuel pump. If not that it will probly be the fuel presure regulator. I have the same year truck and i hear this problem alot. Mine was a combonation of the fuel pump and the mass air flow sencer.
