Just bought truck 2 weeks ago w/99,000 miles. At Dealers lot had very low fuel in tank. After adding fuel at station it wouldn't restart. After Dealer got it restarted drove home (55 miles) truck ran great. Got home tried to restart, wouldn't start. A mechanic came over and loosened the cover on the upper fuel filter housing , cranked over until fuel came out, closed cover. The truck restarted and ran great for about a week, now starting to have the starting problem again. It cranks over but won't start. Intermitant. Can hear the fuel pump cycle for 5 sec and shut off. No overheating or any other issues with truck.
