Dodge Ram 2500 Engine Will Crank But Not Start Due to Fuel Return Line Leak

(16 reports)

If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.

Engine turns over but won't fire. Have had no previous problems starting this truck has always started right away. -
drove it turned it off would not restart just cranks -
After replacement of the lift (transfer) pump AND the VP44 main pump, after about 60 miles I noticed and smelled diesel dripping onto the ground right under the driver's seat. The mechanic said that the rubber fuel return line had failed where it goes thru/across a bracket. Both myself and the mechanic had noticed a serious lack of power/snap" while driving...I pick up the truck this afternoon.. will see if the power is back to where is used to be!! -
