Additional Info
Duramax LML CP4 Pump Failure
The CP4 fuel injection pump in 2011-2016 Duramax trucks suffered high-pressure fuel pump issues due to lack of lubrication. The CP4 was designed to be a more efficient pump than its predecessor, the CP3 pump. However, the CP4 proved to be less reliable than the CP3. An LML CP4 pump failure will present itself with a hard start or no start condition and can result in the following trouble codes: P0087, P0088, P0191, or P128E. This can be confirmed by removing the CP4 pump and fuel pressure regulator and checking for cracks and metal debris on the fuel pressure regulator screen.
