YES 1 Check for trouble codes. Codes found? YES NO 2 Check battery connections and voltage. Is voltage above 12.60? YES NO See priority listing in Table 4-5. Does battery pass load test? Recharge battery. YES NO 3 Check spark plug condition, replace if fouled. Check spark at both plugs while cranking. Spark present? Replace battery. YES NO Check compression. If compression is good, check fuel system. Turn ignition ON and engine stop switch to RUN. Does check engine lamp illuminate for 4 seconds? immediately after Key ON? YES NO 4 Check battery voltage at Terminal B of coil connector [83B] using DVOM. Battery voltage present? See 4.11 NO SPARK/NO ICM POWER. YES NO STOP Go to Test 4.9 (Part 2 of 3).

HOME Test 4.9 (Part 2 of 3) ENGINE CRANKS, BUT WILL NOT START 5 6 Continued from Test 4.9 (Part 1 of 3). Install Breakout Box and test light for the next inspection. Front coil code: Check between Terminals 1 and 6 on Breakout Box. Rear coil code: Check between Terminals 1 and 7 on Breakout Box. Does test lamp flash when engine is cranked? YES NO Check coil connections. Connections OK? YES NO 7 Connect Breakout Box. Check continuity between socket A of connector [83B] and terminal 7 (BK) on Breakout Box. Measure resistance between socket C of connector [83B] and terminal 6 (BK) on Breakout Box. Is resistance less than 1.0 ohm? Test spark plug cable resistance. See 4.12 MISFIRE. Resistance OK? Repair. YES NO YES Plug wires in correct coil towers? NO Replace spark plug cables. Connect DVOM to terminals 8 and 9 (BK) of connector [10] on Breakout Box and set it for AC volts. Crank engine. Does DVOM read 1 VAC minimum? Poor connection at connector [10B] or open in harness between coil and ICM. Repair open. YES NO YES NO Replace coil. Route correctly. STOP Go to Test 4.9 (Part 3 of 3). 8 Disconnect connector [79]. Check connector for moisture and corrosion. Check wires for chafing. Connect DVOM to terminals 1 and 2 of connector [79A]. Crank engine. Does DVOM read 1 VAC minimum? YES NO Check for continuity between socket 1 of connector [79B] and terminal 8 of connector [10] on Breakout Box. Continuity present? With meter still connected, check for resistance. Is resistance 600-1200 ohms? YES NO YES NO Locate and repair open on BK wire between socket 2 of connector [79B] and socket 9 of connector [10B]. Locate and repair open on R wire between socket 1 of connector [79B] and socket 8 of connector [10B]. Remove and inspect CKP sensor. Remove any debris on sensor. Reinstall sensor. Replace CKP sensor. 2004 Touring: Engine Management (Carbureted) 4-21
