You need to bleed the air out. RAVE says:
1. Turn the ignition switch off and wait 15 seconds.
2. Turn the ignition switch to position II and wait 3 minutes (this ensures that the fuel system purges all the air from the fuel rail within the cylinder head).
3. Fully depress the throttle pedal.
4. Keeping the throttle pedal fully depressed, crank the engine.
5. As soon as engine speed exceeds 600 rev/min, release the throttle pedal and the ignition switch.The engine must not be cranked continuously for more than 30 seconds at any one time.
6. If the engine fails to start, repeat the above procedure.
