Test NS-9A - Correcting No Crank Condition

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure transmission is in Park position. Using scan tool, read Park/Neutral (P/N) switch sense. If scan tool does not display PARK, repair open P/N switch ground circuit (Black/Orange wire). Perform TEST VER-1.
  2. If scan tool displays PARK, disconnect starter relay connector. Using scan tool in voltmeter mode, check voltage on starter relay connector fused battery circuit (Red/Yellow wire). If voltage is less than 10 volts, repair open Red/Yellow wire. Perform TEST VER-1.
  3. If voltage is more than 10 volts, check voltage on starter relay connector ignition switch output circuit (Yellow wire). While observing scan tool, hold ignition switch in RUN position. If voltage is less than 10 volts, repair open Yellow wire. Perform TEST VER-1. If voltage is more than 10 volts, go to next step.
    WARNING: Engine may crank in following step. Keep away from moving engine parts.
  4. Ensure transmission is in Park position and parking brake is set. Briefly connect a jumper wire between starter relay connector fused battery circuit (Red/Yellow wire) and starter relay output circuit (Brown wire). If starter cranks, replace starter. Perform TEST VER-1. If starter does not crank, note if solenoid clicks when jumper wire is connected. Go to next step.
  5. Disconnect jumper wire. Disconnect starter solenoid connector (Brown wire) from starter solenoid. Using an external ohmmeter, check resistance of Brown wire between starter relay output connector and starter solenoid connector. If resistance is more than 5 ohms, repair open Brown wire. Perform TEST VER-1.
  6. If resistance is less than 5 ohms, install starter relay. Check battery cables for high resistance. If either battery circuit has a voltage drop of more than .2 volt, repair battery circuit for high resistance. Perform TEST VER-1. If voltage drop for either battery circuit is less than .2 volt, go to next step.
  7. If starter solenoid clicked when jumper wire was connected in step 4), repair starter for a mechanical failure. Perform TEST VER-1. If starter solenoid did not click, replace starter solenoid. Perform TEST VER-1.
