Probable Cause: 1. Battery Has Low Output Make Reference to Problem 27.2. Wires Or Switches Have Defect:Make Reference to Problem 27.3. Starter Motor Solenoid Has A Defect:Make Reference to Problem 26.4. Starter Motor Has A Defect:Make Reference to Problem 26.5. Inside Problem Prevents Engine Crankshaft From Turning:If the crankshaft cannot be turned after the drive equipment is disconnected, remove the fuel nozzles and check for fluid in the cylinders while the crankshaft is turned. If fluid in the cylinders is not the problem, the engine must be disassembled to check for other inside problems. Some of these inside problems are bearing seizure, piston seizure, wrong pistons installed in the engine, and valves making contact with pistons.Problem 2: Engine Will Not Start
Probable Cause: 1. Slow Cranking Speed:Make reference to Problem 27.2. No Fuel In The Housing For The Fuel Injection Pumps:Fill the housing for the fuel injection pumps with fuel with the priming pump. Remove the air with the bleed valve.3. Dirty Fuel Filter:Install new fuel filter.4. Dirty or Broken Fuel Lines:Clean or install new fuel lines as necessary.5. No Fuel To Cylinders:Put fuel in fuel tank. "Prime" (remove the air and/or low quality fuel from the fuel system).6. Bad Quality Fuel:Remove the fuel from the fuel tank. Install a new fuel filter element. Put a good grade of clean fuel in the fuel tank.7. Fuel Has "Cloud Point" Higher Than Atmospheric Temperature ("Cloud Point" = Temperature Which Makes Wax Form In Fuel):Drain the fuel tank lines, and fuel injection pump housing. Change the fuel filter. Fill the tank with fuel which has the correct "cloud point" and remove the air from the system with the priming pump.8. Wrong Fuel Injection Timing:Make adjustment to timing.9. Over fueling Spring Not Installed:Install over fueling spring.Problem 3: Misfiring Or Running Rough
Probable Cause: 1. Air In The Fuel System:Find air leak in the fuel system and correct. Remove air from fuel system. See Fuel System in Testing and Adjusting.2. Fuel Pressure is Low:Make sure
