Spark Check

  1. Perform self diagnostic QUICK TEST to check for ignition-related fault codes, and repair as necessary. See QUICK TEST in the TESTS W/CODES - EEC-IV (2.0L) article in the ENGINE PERFORMANCE section. If no fault codes are retrieved, check ignition system wiring harness connectors for damage, corrosion and tight fit. See the WIRING DIAGRAMS - 2.0L article in the ENGINE PERFORMANCE section.
  2. If no fault codes are retrieved and vehicle starts, problem is intermittent. Go to the TESTS W/O CODES - EEC-IV (2.0L) article in the ENGINE PERFORMANCE section. If no fault codes are retrieved and vehicle has a no-start condition, connect a high-output spark tester between ignition coil wire and engine ground. Check for spark at coil wire while cranking engine. A consistent Blue spark should be present.
  3. If spark is present, go to step 4). If no spark is present, remove distributor cap, and crank engine to ensure distributor rotates. If okay, check resistance of coil secondary wire. Resistance should be less than 7000 ohms per foot. Service coil wire if resistance is not as specified, and retest. If spark is still not present after servicing coil wire, see the appropriate SYSTEM/COMPONENT TESTS - EEC-IV (2.0L) article in the ENGINE PERFORMANCE section.
  4. Inspect distributor cap and rotor for cracks or carbon tracking. Service as necessary and test spark output at spark plugs. If spark is present at spark plugs and engine will not start, go to the TESTS W/O CODES - EEC-IV (2.0L) article in the ENGINE PERFORMANCE section.
