Results for “Starter”
Diagnostic tests4
Starter-circuit test
Separate start-request, interlock, cable, ground, solenoid, and starter-motor evidence before bypassing the circuit or replacing the starter.
Test-first procedureBattery voltage and condition test
Separate state of charge, battery condition, and connection problems before blaming the starter or alternator.
Test-first procedureVoltage-drop test
Find resistance in a loaded power or ground path without assuming that continuity or an unloaded voltage proves the circuit is healthy.
Test-first procedureCrank-but-no-start evidence test
Separate missing ignition, fuel delivery, control, synchronization, and mechanical evidence after the engine is confirmed to crank.
Test-first procedureDiagnostic guides2

The engine does not rotate when starting. Separate battery, cable, starter-control, interlock, security, and starter faults before replacing anything.
intermediateEngine cranks but won’t start
