You may need to bleed the fuel system.
Open the air bleed valve on the fuel manager/filter.
Connect a hose to the air bleed valve and place the other of the hose in a suitable container.
The diesel/water mixture is flammable and may be hot. To avoid personal injury or property damage, do not allow the diesel/water mixture to come in contact with skin, open flame or a hot engine. Do not overfill the container holding the fuel mixture as heat from a warm engine or any another heat source may cause the fuel to expand and leak from the container that may lead to a fire.
Remove the F/SOL fuse from the fuse panel.
Crank the engine in short intervals of 10-to-15 seconds until clear fuel is observed at the air bleed hose (wait for 1 minute between cranking intervals)
Remove the hose and close the air bleed valve.
Install the F/SOL fuse and start the vehicle. Allow the vehicle to run at idle for 5 minutes.
Check for fuel leaks, and clear any Diagnostic Trouble Code's (DTCs)
