Record by record
15 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.
Symptom
Component named as the cause
Work done
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesIntermittent stall, misfire or crank no start (Ignition 1 feed wire broken near C148/C149)2
Manufacturer communication2005–2006 GMC YUKON ・ 2006-10-01
Intermittent stall, misfire or crank no start: Ignition 1 feed wire broken near C148/C149
1Fault
- The engine may intermittently stall, misfire, or crank without starting, and there may be no trouble codes set.
2Finding the cause
Possible causes
- The pink Ignition 1 power feed wire may break inside the insulation near connector C148/C149.
Steps to confirm (in the document’s order)
- Complete the SI diagnostics first; if they are inconclusive and the concern can be duplicated, inspect for a loss of Ignition 1 voltage to the ignition coils.
- Wiggle test the ignition coil harnesses to see if the concern can be duplicated.
- Inspect splices S160 and S159 for loose connections, and connectors C148 and C149 for wires breaking near the connector.

- P0302
- P0303

- Rough idle, crank no start, extended crank or misfire, with the engine warning lamp on and DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 or P0308 set.
- When the engine is cold, compression on multiple cylinders may be zero.
- The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.
2Finding the cause
Possible causes
- Major carbon build-up on the intake and/or exhaust valves from fuel contamination or incomplete burning of the fuel; misfires should not appear before at least 8,000 km (5,000 mi).
3Correction
Repair
- If there is no valve damage and no cam follower out of place, perform the cleaning procedure to free sticking valves and remove carbon from the valves and pistons.
- If valves are damaged or cam followers are out of place, make the engine mechanical repairs first and then perform the cleaning procedure to prevent a return.
- Fill Cleaner Kit J-35800-A with about 650 ml (22 oz, 2 cans) of Air Intake, Combustion Chamber Cleaner and set the air pressure at the tool to 260 kPa (40 psi).
- With GDS 2 or a scan tool, command engine idle to 2000 rpm so the engine does not stall.
- With the engine at operating temperature in a well-ventilated area, slowly and carefully induce the cleaner into the engine, taking about 3 minutes.
Parts
- The Top Engine Cleaning Kit (ACDelco Air Intake, Valve and Combustion Chamber Cleaner and ACDelco Fuel System Cleaner 44K) is 19435372 for the U.S. and Canada.

- Misfire or rough idle
- Does not start
- Warning light
- Check engine / Service Engine Soon
- P0300
- P0308
- Customers may complain of a MIL and/or engine misfire, rough idle, extended crank, or crank no start.
- One or more misfire codes (DTC P0300-P0308) are found stored in the ECM.
2Finding the cause

- The condition may result from major carbon build up on the intake and/or exhaust valves due to fuel contamination or incomplete burning of the fuel.
Steps to confirm (in the document’s order)
- With the engine cold, compression on multiple cylinders may read 0 PSI (= 0 kPa).
- The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.
3Correction
Repair
- If there is valve damage or cam followers are out of place, make the mechanical repairs first, then perform the cleaning procedure to keep the concern from returning.
- With the engine at operating temperature, slowly induce a bottle of GM Upper Engine and Fuel Injection Cleaner with RPM held above idle so the engine does not stall (typically around 2,000 RPM).
- Turn the engine off and let the cleaner soak for 2.5 to 3 hours.
- To complete the repair, change the engine oil and filter.
Parts
- Upper Engine and Fuel Injector Cleaner is P/N 88861803 (in Canada, P/N 88861804).
