FaultCrate・Intermittent stall, misfire or crank no start (Ignition 1 feed wire broken near C148/C149)
The engine may intermittently stall, misfire, or crank without starting, and there may be no trouble codes set.
The pink Ignition 1 power feed wire may break inside the insulation near connector C148/C149.
What to do
- 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.
