Here is the thread on changing out the fuel filter.

I doubt it is your fuel pump but a test of fuel pressure will tell, after you change out the filter.

Checked fuel pressure have about 18 psi. Gonna change fuel filter and retest.

How many miles on the truck?

180000 miles

Well if the fuel filter has never been changed that could be the problem, but then it could have also trashed your fuel pump as well. If you have to change out your fuel pump there is a thread on here as well showing how to do that.

Fuel filter changed was not the problem. Going for fuel pump next.
