Basic System Check

  1. Perform OBD system check. See ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK in appropriate SELF-DIAGNOSTICS article. After performing OBD system check, go to next step.
  2. Check battery condition. If batteries are okay, go to next step. If condition of batteries is not okay, go to step  23.
  3. Check fuel level in tank. If fuel level is okay, go to next step. If fuel level is not okay, go to step  23.
  4. Check quality of fuel. If fuel quality is okay, go to next step. If fuel quality is not okay, go to step  23.
  5. Check glow plug operation. If glow plug operation is okay, go to next step. If glow plug operation is not okay, go to step  23.
  6. Check for proper engine cranking speed. If engine cranking speed is okay, go to next step. If engine cranking speed is not okay, go to step  23.
  7. Check for restriction in fuel return system. If restriction is not present, go to next step. If return line is restricted, go to step  23.
  8. Check injection pump ground wire located on top of injection pump. If ground wire is okay, go to next step. If ground wire is not okay, go to step  23.
  9. Install scan tool. Using scan tool, check for any data. If data is displayed, go to next step. If data is not displayed, see DLC DIAGNOSIS OR NO SCAN TOOL DATA in appropriate SELF-DIAGNOSTICS article.
  10. Using scan tool, monitor Vehicle Theft Deterrent (VTD) FUEL DISABLED parameter on ENGINE DATA 1 list. Crank engine. If scan tool displays ACTIVE while engine is cranked, diagnose VTD system. See appropriate ANTI-THEFT SYSTEMS article in ACCESSORIES & EQUIPMENT. If scan tool does not display ACTIVE, go to next step.
  11. Loosen injector line at injector. Crank engine and check for fuel. Repeat procedure for all injectors. If fuel flows from each fuel line, go to step  17. If fuel does not flow from each fuel line, go to next step.
  12. Disconnect optical/fuel temperature sensor. Attempt to start engine. If engine starts, go to step  16. If engine does not start, go to next step.
  13. Reconnect optical/fuel temperature sensor. Disconnect fuel solenoid driver at fuel injection pump. Measure voltage between ground and fuel injector control circuit at harness connector while cranking engine. If voltage is 1.2 volts or greater, go to next step. If voltage is less than 1.2 volts, go to step  18.
  14. With fuel solenoid driver still disconnected, probe solenoid ground circuit at harness connector with test light connected to battery voltage. If test light illuminates, go to next step. If test light does not illuminate, go to step  19.
  15. Turn ignition on. Ensure fuel solenoid driver is still disconnected. Using test light connected to ground, probe ignition feed circuit at fuel solenoid harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step  21.
  16. Replace fuel injection pump. After repairs, go to step  25.
  17. Injection system is okay. Check for intermittent problem. See appropriate TROUBLE SHOOTING - NO CODES article.
  18. Check for open or short to ground in fuel injector control circuit between fuel solenoid driver and PCM. Repair as necessary. After repairs, go to step  22. If circuit is okay, go to step  20.
  19. Check closure signal ground circuit for open between fuel solenoid driver and PCM. Repair as necessary. After repairs, go to step  22. If circuit is okay, go to next step.
  20. Check for poor connections at fuel solenoid driver and PCM harness connectors. Repair as necessary. After repairs, go to step  22. If connections are okay, go to step  24.
  21. Repair open in ignition feed circuit. After repairs, go to step  25.
  22. Repair circuit as necessary. After repairs, go to step  25.
  23. Repair as necessary. After repairs, go to step  25.
  24. Replace PCM. Perform PCM relearn procedures. After repairs, go to next step.
  25. Using scan tool, select DTC, CLEAR INFO function. Attempt to start engine. If engine starts and continues to run, go to next step. If engine does not start, or starts and stalls, go to step  2.
  26. Allow engine to reach normal operating temperature. Using scan tool, select DTC, FAILED THIS IGN function. If any DTCs are set, diagnose DTCs. See appropriate SELF-DIAGNOSTICS article. If no DTCs are set, go to next step.
  27. Using scan tool, select CAPTURE INFO, REVIEW INFO function. If any other DTCs are set that have not been diagnosed, diagnose DTCs. See appropriate SELF-DIAGNOSTICS article. If DTCs are not set, system is okay.
