Re: HELP! 6.0 ran out of fuel,now won't start!
1. put the motorcraft filter back in. 2. dont worry about taking the banjo bolts off the back, crack the cap of the fuel bowl and have someone watch it while you cycle the key, once its steady tighten the cap up and crank. Should fire. Another thing folks DIDNT mention. You changed oil cooler correct you have air in the system, fact you ran out of fuel is one thing, but the other fact is you didnt run the air out of the oil side so your gonna have starting issues. Stock gauge moves at 7psi not nearly enough to start.
After you see fuel coming from the bowl tighten and crank it 20 secs, and rest crank it 20 secs and rest do not burn up the starter, you should see the oil gauge rise slowly, once it builds enough pressure it should fire right up and DO not shut it off till you run the air out. After a few cranks hold the crank and listen you should begin to here it try and turn over once it gets its pressure built back up.
