Crank, No Start

So I have a 2002 AmTran/International with the DT466. Bus started fine a couple days ago, let it high idle for 10-15 minutes while I was working on a couple interior things, shut it down, no big deal. It was in the 20's the other day, it's mid to upper 50's right now.

Today I attempted to start it, it just cranks and cranks and cranks, but it never fires. The fuel level is a bit low, it's indicating 1/4 tank on the dash, and the bus is parked nose down on a incline, so maybe fuel?

I checked a few fuses, etc.. no dice. Everything looks ok. Any quick suggestions as to what I might try? The engine cranks fine, I went ahead and threw a battery charger on there since I've cranked on it a bit..

I'm hearing in the threads that 1/4 is too low...might have lost prime...there's another thread similar to this one

It actually depends on where your fuel pickup hoses are regardless of the fuel reading on a slope.
The fuel pic up could be on the high side of the tank and the unless guage on the forward/lower side of the tank?
An observation?
Most diesel vehicles require a semi level parking spot especially on low fuel.
Add 5-gallon to it and charge the batteries and see what happens.
Some need the injector lines broke loose to bleed and some pick it up?
That really depends on how much air your system picked up?
Look and see where your fuel pump pick up tube is in your system and make sure
You have enoug in your tank (regardless of slope) for it to pick up.
If your fuel pick up tube is at the uphill side of the tank and your guage is reading a 1/4
Just an observation?
Good luck

I havent looked at where the pickupos are in my navistar tanks as far as up and down.. but IO know my gauge stops reading when I get just below that last line .. the 1/4 line? it never reads any lower.. so I am guessing the fuel pickup isnt not much below that point...

So, I put 5 gallons in it, no dice. At the filter, I pushed in the schrader valve and I get fuel out of it, no huge pressure, but enough to coat my hand.

I'm kind of baffled, to be honest. To go from running great to not starting within a few days time. I'm going to leave the charger on there overnight, top off the batteries.. might throw another 5 gallons in there, just to be safe.

I would definitely pump the fuel primer until it's firm. Fuel should squirt out of the schrader valve.

I will try that this evening. I hope that it's not an injection seal and the HPOP is keeping it from firing.

You might want to check your fuel filter/water separator and drain. When your fuel gets that low your into the swamp.
