Duramax LLY / LBZ Injection Pump 2004-2007 CP3 Exergy E04 10405

Exergy diesel high-pressure injection pump for the Duramax LLY / LBZ (2004-2007). Listed for one application: Duramax LLY / LBZ engines, 2004-2007, in Chevrolet, GMC applications. Confirm your engine code and year against this listing before ordering.

What it does

The injection pump makes the pressure the injectors meter. When it fails it can take the whole fuel system with it: a grenading CP4 sends metal through the rails, lines and injectors. A new or reman pump restores rail pressure, and on a known-weak pump a conversion is cheaper than the failure.

Fits

• Chevrolet vehicles with the Duramax LLY / LBZ engine, 2004-2007
• GMC vehicles with the Duramax LLY / LBZ engine, 2004-2007

Fixes

• low rail pressure codes and a no-start
• hard starting and a loss of power under load
• metal in the fuel system after a pump failure
• a preventative conversion on a known-weak pump
