Diagnose and Fix Corroded or Loose Starter Cables and Connectors
If your 01-07 Volvo won’t start, fear not—it’s a common problem on the 01-07 Volvo S60, S80, V70, and XC90 to turn the ignition key and not hear or feel the engine crank or turnover. These Volvos usually have a problem with a corroded or loose electrical connector on the starter. We’ll explain what to look for and how to fix this problem if you turn the key and nothing happens on your 01-07 Volvo.
Signs of Volvo Starting Problems
- Turn the key and nothing happens—no cranking noise or sound of the engine turning over
It’s obvious the symptom is that your Volvo won’t start, but this specific article applies to the 2001-2007 Volvo S60, S80, V70, and XC90 and is about a Volvo that doesn’t start at all. This means when you turn the key in the ignition, nothing happens. An engine that has trouble starting might make a loud noise as it tries to crank or turn over, but a key symptom of an issue with the starter’s electrical connector on these vehicles is the absence of any effect from turning the key.
Causes of a Volvo that Won’t Start
While the battery or starter could be defective, usually a wire that goes to the starter solenoid and tells it to engage tends to corrode or loosen. This prevents the starter from receiving a signal, indicating it should turn on.
How to Fix a 01-07 Volvo that Won’t Start
The starter is located underneath the engine and a red wire provides power to the starter solenoid. If the electrical connector is failing, replacing it isn’t always necessary.
How to Check the Starter’s Electrical Connector
- Check the Electrical Connector for Looseness
Check if the electrical connector is loose and needs to be reconnected
- Check the Electrical Connector and Wires for Corrosion
Inspect the wire and connector for corrosion or discoloration on the connector terminals
- Clean the Corrosion
If there is corrosion in the electrical connector’s terminals, clean out the connector with a pick tool
- Reconnect the Connector
Reconnect and make sure it connects firmly
- Check the Connector for Play
Test the connector for looseness or “play”
- Crimp the Connector to Fix Any Play
If there is looseness, try crimping down on the electrical connector with a pair of pliers
- Replace a Defective Connector
If the connector proves to be defective, replace it by cutting the old one and pigtailing a new connector to the wire
