I posted earlier about my car suddenly not starting after being parked overnight. Turned the key 2 clicks waited on glow plugs to warm. went to fire it up and nothing. Only a click from the relay under the passenger dash. No noise at all from the motor or solenoid. Did some testing with a multimeter. Battery was fine at 12.6 volts. Main wire from battery to starter motor was showing 12.6 volts. However the trigger wire from the ignition was showing poor voltage when attempting to start. Anyone know what could be causing this.
