I have a 2004 2400HD truck. It will not start. This is the third time this has happened. First two times required towing to dealer and about a total of $1500. Dealer fixed both times, but it's only been about three months since the last repair. Ran fine yesterday, but went out this AM and it urns over fine but won't start. Primed the fuel filter (hopefully correctly) but it still just turns over. Last repair was described as replacing a one-way, no return valve back to the fuel tank. They said fuel was draining out of the filter back into the tank. Any ideas/suggestions?
