Unlocking Engine Potential A Guide to Starter Motor Optimization

2011 Murano that will not try to crank when the starter button is pushed. All lights and gauges work. Battery has been load tested and new starter. Open the fuse and relay box under the hood (labelled IPM). Turn the cover over and look for the 'starter' relay. Take that relay out and swap with another one ... The starter draws power from the battery through thick cables that can channel high electric current. What Wire Goes Where on a Starter Solenoid ... Since that small amount of electrical current is unable to power the starter, it instead powers a tiny electromagnet, which closes a much larger circuit. Check the starter motor solenoid itself. The wire that operates the solenoid is a simple push on affair and often falls off. If there is no power to the small solenoid wire then you need to test the starter relay, the contacts inside the relay could be dirty. The common starting problems in preludes are related to the main relay and the immoblizer, either of which will still allow the motor to crank ... When the key is turned to Start, power comes to the relay coil from the ignition switch, and pin 16 would normally be at or near ground voltage. The power to the solenoid has to pass through the fusible link, the ignition switch, the clutch start switch, and the theft deterrent relay to get to the ... There are several different reasons the BCM will not send a signal to the starter relay. One could be a simple popped fuse.
