Vehicle
2011 Chevrolet Silverado 3500 HD; 6.6L Eng VIN 8 Eng CD LML

Title
Engine Swap, No Start

Complaint
After swapping the engine with a used engine, the vehicle won’t start up.

Cause
Found the CP4 pump in the new(used) engine was faulty and the new fuel filter installed wasn’t leaking but was sucking air into the system. Seems the lip on the fuel filter was too big for the O-ring used to make a proper seal.

Correction
Replaced the faulty CP4 pump and fuel filter, which solved the issue and allowed the engine to fire up.

SureTrack® is a powerful value-added feature available with select Snap-on diagnostics tools. It offers an exclusive combination of expert knowledge and detailed parts replacement records, all wrapped in an interactive community.
