replace the fuel filter. i bet it's plugged up solid.you might need a special tool to get it off, some of the older ones had plastic tabs that just pop off. if you have a metal clip on wither side of the filter buy a quick disconect tool that. you need the metal tool with 2 sizes, looks kind of like scissors, spray the fittings with wd-40 before trying to remove it. oh yeah the filter is located in the drivers side frame rail. good luck!! hope this helps
