Your description sounds like the lift pump failed. The lift pump is located on the drivers side of the engine about 2/3rds back from the front of the engine. Make sure there are no air leaks between the lift pump and the fuel tank. Hard or no start can be caused by many conditions. The following points will help in diagnosing hard start concerns. Low fuel pressure or air entering the fuel system. This can cause a low rpm miss/instability, white smoke, hard starting, or low power. Basic fuel system diagnostics should be followed. Technical Service Bulletin 14-07-96 should be referenced when diagnosing fuel concerns Loss of fuel system prime. A leak in the return portion of the fuel system can allow air to enter the injection pump eventually. An area to inspect is the 5/16 inch rubber hose that connects to a steel line on the back of the injection pump. Replace the line if leaking is found or suspected. NOTE: DO NOT EXCEED A MAXIMUM CRANKING TIME OF 30 SECONDS AT A TIME WHEN HARD STARTING IS EXPERIENCED.
