New Bus, New problem

[ledzepp2994]

Ok so just bought a 1995 E350 Short bus, with the 7.3 power stroke. When i got it everything seemed to be fine engine wise, Needed some break work and wheel bearings did all that, The real problem came after I had it up and running, Turns out the fuel gauge doesn't work, and what looked like half a tank was really almost nothing, so it ran out, not completely dead but coughing and sputtering, went out and got 10 gallons and filled it back up, got it up my drive way where it first started to die, its a steep hill, as i was turning around to back it in to the garage it started to choke and then died, then i started it back up got it in the garage and it did the same thing, and once more, couldnt keep it running. tried bleeding it at the fuel pump and the connectors that run into the back of the fuel rail,



I figured air in the system, bleed the injectors, first of all how do i get to them on these engines?

Then this morning I got up went out to try bleeding it again, it wouldn't fire, turns over and cranks fine, have had the batteries trickle charging all night and throughout the day, they are all good, I plunged in the block heater to help things out a bit,

So far i have, Bleed it at the fuel pump, bleed the two lines on the forward side of the fuel pump, bleed it at the two connectors at the back of the engine where it goes in to the fuel rail, opened up the return line under the bus and made sure i had good flow there, replaced the fuel filter, tested pressure at the fuel pump, 50psi.

I am new to these engines, what am i missing.

Before yesterday it ran fine, started on the first turn every time.
