Engine Swap, No Start

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

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.

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.
