Probable Causes
Engine shutdown switches (if applicable)
Circuit breakers
Diagnostic codes
Battery cables and/or batteries
Starting circuit
Electrical power supply
Internal engine problemRecommended Repairs
Engine Shutdown Switches (If Applicable)
Verify that there are no active shutdown switches.Circuit Breakers
Check the state of each of the circuit breakers. Reset the circuit breakers if the circuit breakers are tripped. Prior to returning the engine to service, determine the condition that caused the circuit breaker to trip. Make the necessary repairs.Diagnostic Codes

Check the electrical power supply. If necessary, refer to the circuit test Troubleshooting, "Electrical Power Supply - Test".Internal Engine Problem
Remove the glow plugs. Refer to Disassembly and Assembly.
Attempt to rotate the crankshaft through 360 degrees in both direction. If the crankshaft rotates correctly but fluid is expelled from the hole for the glow plug, investigate the cause of the fluid in the cylinder. Refer to Systems Operation/Testing and Adjusting.
If the crankshaft rotates correctly and no fluid is expelled, install the glow plugs. Refer to Disassembly and Assembly.
If the engine does not rotate in Step 2, disassemble the engine. Refer to Disassembly and Assembly.
Inspect the internal components for the following conditions:
Seizure
Broken components
Bent components
