What fuel lines did you disconnect? If you have air in the low pressure side you can use the Shrader valve on the fuel cooler. Just cycle key when valve is pressed in and cycle for 30 sec or so or until you cant hear bubbles coming out. If it is in the high side you have to loosen the banjo bolt on the fuel cooler while you cycle the key until there is no more bubbles. Low pressure first then high pressure

the manual talks about how to purge the air after a fuel filter change. You cycle the key to just the on position about 6-8 times.
Each time you move the key to the on position (without attempting a start). You hold it there for around 30 seconds, giving the low pressure pump time to circulate and send the fuel to the top mounted filter.
After you do this routine then you can attempt the start.

could be...maybe he will sign on later and see the info. Might be working on it right now.
I know my first fuel filter change I could not get it to purge...ended up hitting the fuel cutoff switch and held it down while cranking and finally got it to fire.

Yea sometimes they can be a pain. Kinda of curious of which lines he unhooked. Hate for him to push air to his high side. Maybe he will get back on. Later bro
