Amigo & Rodeo 2.2L

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2000 Isuzu VehiCROSS, 2000 Isuzu Trooper, 2000 Isuzu Rodeo, 2000 Isuzu Hombre, and 2000 Isuzu Amigo. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Relieve fuel pressure before connecting fuel pressure gauge. See FUEL SYSTEM PRESSURE RELEASE  under FUEL SYSTEM.
  1. Perform On-Board Diagnostic II (OBD-II) System Check. See SELF-DIAGNOSTICS - INTRODUCTION article. After performing OBD-II system check, go to next step.
  2. Install Tech II scan tool. Following manufacturer's instructions, check for stored DTCs. If no DTCs are stored, go to next step. If any DTCs are stored, diagnose DTC. See appropriate diagnostic test procedure in SELF-DIAGNOSTICS - 2.2L - EXCEPT HOMBRE article.
  3. Check IG. COIL fuse (15-amp) and ENG. fuse (15-amp) located in dashboard fuse block. Check ECM fuse (15-amp) located in underhood fuse/relay block. If any fuse is blown, go to next step. If fuses are okay, go to step  5.
  4. Check for short to ground in appropriate circuits. See ENGINE PERFORMANCE WIRING DIAGRAMS article. Repair as necessary. Replace any blown fuses.
  5. Turn ignition on. With a test light connected to ground, probe IG. COIL fuse (15-amp) and ENG. fuse (15-amp) located in underdash fuse block and ECM fuse (15-amp) located in underhood fuse/relay block. If test light illuminates at all fuses, go to step  7. If test light does not illuminate at all fuses, go to next step.
  6. Repair open in appropriate ignition feed circuit. See ENGINE PERFORMANCE WIRING DIAGRAMS article. Retest system.
  7. Disconnect ignition secondary wire at coil No. 1. Install spark tester at end of secondary wire. While cranking engine, check for crisp, Blue spark. If poor or no spark is found, go to next step. If spark is okay, go to step  16.
  8. Disconnect Ignition Control Module (ICM) harness connector. Check for open or short circuit in wires between ICM and PCM. See ENGINE PERFORMANCE WIRING DIAGRAMS article. If wires are okay, go to step  10. If any problems were found in either wire, go to next step.
  9. Repair open or short circuit in wires between ICM and PCM as necessary. Retest system.
  10. Turn ignition on. Using DVOM, measure voltage at Black/Orange wire of ICM harness connector. If battery voltage exists, go to step  12. If battery voltage does not exist, go to next step.
  11. Repair open circuit in Black/Orange wire between IG COIL fuse (15-amp) and ICM. Retest system.
  12. Check for open in ICM ground circuit (Black/Red wire). If problem is found, go to next step. If no problem is found, go to step  14.
  13. Locate and repair open circuit in in ICM ground (Black/Red wire). Retest system.
  14. Replace ICM. Attempt to start engine. If engine does not start, go to next step.
  15. Replace and reprogram PCM. See PROGRAMMING in SELF-DIAGNOSTICS - 2.2L - EXCEPT HOMBRE. Retest system.
  16. Turn ignition off. Using DVOM, measure ignition coil primary resistance. If primary resistance is .8-18 ohms, go to next step. If resistance is not as specified, go to step  18.
  17. Measure ignition coil secondary resistance. If secondary resistance is 9000-12,000 ohms, go to step  19. If secondary resistance is not as specified, go to next step.
  18. Replace ignition coil. Retest system.
  19. Measure resistance of each coil-to-spark plug secondary ignition wire. If resistance is greater than 10 k/ohms per foot, go to next step. If resistance is not greater than specification, go to step  21.
  20. Replace any spark plug wires with resistance greater than 10 k/ohms per foot. Verify engine operation. If no faulty spark plug wires were found, go to next step.
  21. Remove all spark plugs. Inspect spark plugs for fouling, loose or missing electrodes, or cracked insulators. Clean or replace spark plugs as necessary and go to next step. If spark plugs are okay, go to step  33.
  22. Attempt to start engine. If problem still exists, go to next step.
  23. Turn ignition off. Install fuel pressure gauge to fuel supply line test fitting. Turn ignition on. If fuel pressure is 43-55 psi (3.0-3.9 kg/cm2 ) and holds steady, go to step  24. If fuel pressure is not 43-55 psi (3.0-3.9 kg/cm2 ) or does not hold steady, go to next step.
  24. If no fuel pressure is indicated, go to FUEL SYSTEM DIAGNOSIS  under FUEL SYSTEM. If any fuel pressure is indicated, go to FUEL SYSTEM ELECTRICAL TEST  under FUEL SYSTEM.
  25. Install Injector Tester (J-39021) and switch box at injector test connector, and activate fuel injector. If fuel pressure drops, go to next step. If fuel pressure does not drop, go to FUEL SYSTEM DIAGNOSIS  under FUEL SYSTEM.
  26. Pressurize system by turning ignition on. Using injector switch box, test each injector for pressure drop. If a pressure drop exists for each injector, go to next step. If a pressure drop does not exist for each injector, go to FUEL SYSTEM DIAGNOSIS  under FUEL SYSTEM.
  27. Remove Injector Tester (J-39021) and switch box. Connect Injector Test Light (J-39021-45) to injector test harness connector. Crank engine. If any tester lights blink while engine is cranking, go to step  33. If no tester lights blink while engine is cranking, go to next step.
  28. Raise and support vehicle. Disconnect Crankshaft Position (CKP) sensor connector. Turn ignition on. Using a test light connected to ground, probe ignition feed circuit at CKP sensor harness terminal No. 1 (Green wire). If test light does not illuminate, repair open Green wire. Retest system. If test light illuminates, go to next step.
  29. Connect test light between ignition feed circuit at CKP sensor harness terminal No. 1 (Green wire) and ground circuit terminal No. 3 (Black wire). If test light illuminates, go to step  31. If test light does not illuminate, go to step  32.
  30. Check for open or short circuit in Green wire between CKP sensor and PCM. Repair as necessary. Retest system. If no problem was found, go to step  33.
  31. Replace CKP sensor. Retest system. If problem still exists, go to step  34.
  32. Check for open or short circuit in Blue wire between CKP sensor terminal No. 2 and PCM. If no problem was found, go to next step. If problem was found, repair Blue wire as necessary.
  33. Replace and reprogram PCM. See PROGRAMMING in SELF-DIAGNOSTICS - 2.2L - EXCEPT HOMBRE article. Retest system.
  34. Test for fuel contamination. If fuel is not contaminated, go to next step. If fuel is contaminated, clean fuel system as necessary. Replace fuel filter and verify all fuel injectors are delivering fuel. If no problem was found, go to next step.
  35. Check for these possible conditions:
    • Faulty or incorrect camshaft timing belt.
    • Leaking or sticking valves or rings.
    • Excessive valve deposits.
    • Loose or worn rocker arms.
    • Weak valve springs.
    • Leaking head gasket.

    Repair as necessary. See appropriate article in ENGINES. Retest system.
