I have a 2001 dodge ram that has slowly lost power and won't even start now. It tries but it is acting like it is not getting gas. Does anybody have any advice.

Ensure you have installed the same Champion spark plugs that originally came in the truck and that they are not over 3 years old. Likewise, change the fuel filter, if it hasn't been changed in 30,000 miles.
