whole afternoon fooling around with the dang dump truck. Pulled the fuel filters first. Why does this fuel look like mud??????? Fuel in the tank looks dirty. We have been pumping fuel from our main supply storage and it looks fine in everything else. Drin plug on the bottom of the truck fuel tank had seen too much road salt. It IS NOT coming out. Okay remove the fuel tank. A lemon sized hole s rusted out under one band and a pinhole started under the other band. Flush the tank, repair the holes. Flush the tank one more time. Replace the tank, clean the fuel system including bleeding the return side until fresh fuel is seen. Truck still won't start. If you turn it over log enough it will get a slug of fuel and struggle to run for a few seconds and quit. Don't have the proper equipment to test the fuel pressure at the injector return line, so I don't know if the pump has gone bad or if the dirty fuel has messed up the injectors. Any other ideas guys?
