Operator Information
* What happened, and when?* Under what conditions? Was the engine rpm (speed) high or low?Was the engine under load?* Are there any customer or dealer installed systems that could cause this symptom?* What else occurred?* When did the symptoms begin (and what else happened at that time)?LOGGED Diagnostic Codes
* Do they correlate to probable causes?* Did they occur at the same time as the symptoms?* Are some codes Logged repeatedly?Other Symptoms
* Are they related to this symptom?* Do they have common probable causes?Finally, test each probable cause using the tests suggested by the procedure. Be sure to check connectors, especially on intermittent problems! Refer to Section 5: P-501: Inspecting Electrical Connectors for details.P-301: Engine Will Not Crank
This is NOT an electronic system problem. Refer to the Systems Operation, Testing & Adjusting Manual for additional information on the following tests. Probable root causes:* Battery Cables/Batteries* Starting motor solenoid or circuit problem (in system wiring)* Starting motor/flywheel ring gear* Engine accessory* Hydraulic cylinder lock* Internal engine problem Perform the following tests in order:1. Check shutdown switch, battery posts and battery/starter cables for loose connections and corrosion. Remove and clean cables and connections if corroded. Load test batteries. Refer to Special Instruction, SEHS9249, Use Of 4C4911 Battery Load Tester. If necessary, charge the batteries. Refer to Special Instruction, SEHS7633, Battery Test Procedure.2. Test starting motor solenoid operation. Check system wiring to starting motor solenoid.3. Test starting motor operation. Refer to Systems Operation, Testing & Adjusting Manual. Inspect starting motor pinion and ring gear for damage.4. Ensure free movement of driveline. Refer to the Systems Operation, Testing & Adjusting Manual. Check transmission neutral gear indicator for proper operation and adjustment, repair or replace as required.5. Verify timing pin was not left in the flywheel housing after setting valve lash. Use the 9S9082 Engine Turning Tool and attempt to manually turn the engine. If unable to turn the engine, remove and inspect engine accessories that can lock up the engine (air compressor, oil pump, etc). Repair or replace as necessary. Refer to the System Operation Testing & Adjusting Manual.6. Remove injectors and check for fluid in the cylinders.7. Disassemble engine to inspect for internal components that may be seized, broken, bent, out of alignment, etc. Refer to the Disassembly & Assembly Manual.P-302: Engine Cranks But Will Not Start
Probable root causes:* Starting aids/fuel gel (cold temperature operation)* Engine Shutdown Switch setting* Engine/Engine wiring* Personality Module or ECM* Speed/Timing signal; injection timing, incorrect speed/timing wheel orientation assembly, Engine Speed/Timing Sensor calibration error after replacement.* Electrical connections to the unit injector solenoids* Fuel supply* Combustion problem Perform the following tests in order:1. If cold ambient conditions exist, check operation of starting aids. Check cylinder block jacket water heater for malfunction and replace if required. Check for presence of congealed fuel (wax).2. Make sure the Engine Shutdown Switch is in the RUN position. Connect an Electronic Service Tool and verify Shutdown Switch position status. If Electronic Service Tool does not operate, Refer to P-307: Electronic Service Tool Will Not Communicate With ECM. If a shutdown occurs, the keyswitch must be turned to the OFF position, then to the ON position before the engine will start. Aftermarket engine protection devices usually interrupt power to the ECM and prevent communications with the Electronic Service Tool. Check for correct installation and operation of aftermarket engine protection devices. Aftermarket devices may need to be bypassed to continue.3. Check for correct installation of the ECM connectors J1/P1 and J2/P2, Engine Speed/Timing Sensor connector J20/P20, and Unit Injector connectors J5/P5. Refer to P-501: Inspecting Electrical Connectors. If the problem occurs only after the engine is warmed up, the circuit breakers may be exceeding the trip point because of overheating. Check the circuit breakers on the engine, reset if required.4. Verify there is not an Active 253-02 Diagnostic Code. If the diagnostic code is present, Refer to Section 2: Programming Parameters.5. Observe the engine rpm on an Electronic Service Tool Status screen while cranking the engine. If the Electronic Service Tool displays 0 rpm while cranking the engine, there is a problem in the Engine Speed/Timing Sensor circuit. Refer to P-514: Engine Speed/Timing. If engine rpm is present (50 rpm or more while cranking) the Speed/Timing circuitry appears to be operating correctly. Verify that the timing reference gear is installed correctly and keyed to the camshaft by means of the locating dowel. If the gear was installed backwards or flipped over during assembly, the engine will not start. Check calibration of Engine Speed/Timing Sensor, recalibrated if required. Refer to P-614: Engine Speed/Timing Sensor Calibration. Check for proper orientation between crankshaft and camshaft drive gears, repair as required. Refer to procedure in Disassembly & Assembly Manual.6. Make sure the Unit Injector connectors are properly installed. Refer to P-515: Injector Solenoids and perform the Injector Solenoid Test as a quick check to confirm that the ECM can energize the unit injector solenoids.7. Check for a fuel supply problem. P-339: Engine Has A Fuel Supply Problem.8. Check for combustion problems.P-303: Engine Misfires, Runs Rough Or Is Unstable
If the problem is intermittent and cannot be re-created, Refer to P-306: Intermittent Low Power Or Power Cutouts. If the problem is consistent and can be re-created, continue with this procedure. Probable root causes:* Engine Overspeed Warning (CID-FMI) 190-00. The Electronic control Module (ECM) detects and engine speed greater than 2700 rpm for 0.6 seconds. The CID-FMI may be viewed on the display modules or an Electronic Service Tool. It is logged in memory except as noted. The ECM will
