I am presuming this is a diesel. Here are instructions evenif it's gas the same thing

1. Bleed the fuel system by cycling the ignition 3 times in the following sequence: 1. Turn the ignition key ON without cranking the engine.
2. Wait 30 seconds for the fuel conditioning module to run.
3. Turn the ignition key OFF.

2. Test the system for normal operation. If the engine will not start there may still be air in the fuel system, continue bleeding the fuel system with the following steps.

3. NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. To prevent fuel system damage, it is essential that absolute cleanliness is
observed when working with these components.

If air is still present in the fuel system, disconnect the fuel supply tube quick connect coupling from the secondary fuel filter and position aside. For additional information, refer to Quick
Connect Coupling in this section.

4. Install one end of a suitable hose onto the secondary fuel filter and the other end into a suitable container.

5. Cycle the ignition 3 times in the following sequence until no air is present in the fuel system: 1. Turn the ignition key ON without cranking the engine.
2. Wait 30 seconds for the fuel conditioning module to run.
3. Turn the ignition key OFF.
