Hey guys.

I have been chasing a ghost in one of my buses for days now.
It's a 1996 international bus with a T444e engine.
The engine number is 1HVBDABN7VH453479

Short story is that the motor is turning over but there is not even a hickup (so no fuel going in to the cylenders)

It's giving me these codes:
543
124
115
312
224
543
622
615


The Voltage in the batteries drops to 10-10,3V when I start. (new batteries+jump cables to another bus)
Water in fuel light stays on. (even after I drained the filter and took it out)
The bowl is filling up and there is a stream of fuel coming out of the Schrader valve next to it
The Glow plug relay is clicking and giving Voltage to the glow plugs.
I have replaced the IDM.
Engine oil, Transmission fluid and cooling water OK!
It gives me about 150-200 RPM in the dash when the engine turns over.

Any ideas, tips og tricks?

Here is the long version:
Chapter ONE:
The bus was driven in the morgning but in the afternoon it wouldn't start.
And there was a loud clicking noise in the relays above the IDM (behind the air filter).
And since the bus is being used quite far away from where I'm stationed I started to go over the basics trough phone.

Did it run out of fuel? "No" (I got a 99% sure answer to that question)
So I told them to add fuel, check!
Is the RPM meter responding to when it is being started? Yes!
Is it turning on the "wait to start" light? Yes!
Is there enough Voltage on the batteries? Yes! (But I told them to connect it via jumper cables from another bus, just in case)

Chapter TWO:
I drove over there and replaced the IDM
Found out that someone had been messing with the fuse/relay box on the driver side and janked out the buser fuse and vire (the busser that let's you know that a door or a hatch is open). Fixed that and made sure all doors and hatches where closed.
Still NO start.
Found out that the glow plug relay was not "clicking" when the ignition key was turned. Replaced the relay. Still no start.
Found a damaged vire that connencts to the transmisson (probably the one that prevents starting when not in N). Fixed no start.
At that time the wait to start and check engine lights stopped coming on.
found out that the fuses for the IDM and IPR where blown. Replaced them.
After that the Check engine, wait to start and water in fuel lights came on.
Fixed, No start.
Found a blown 20 amp fuse next to battery. fixed!
Now the engine would finally turn over!!!!
The water in fuel stays on and does not go away.

But not even a fart from the engine

I fitted two new batteries, to make sure I have enough cranking power (if there is air in the fuel system).
I tryed about 20 times to start for 20-30 sec. at a time. But nothing.

At that point I tried to get it running with a start sprey.
But no way to get it running.

I would check at the tail pipe or pull the air cleaner lid to see if the engine is pumping air while cranking. Starting fluid will start that engine if it has compression.

you have a bunch of codes (622, 615, 543, 224) related directly to the ECM. If you have 2 of these busses I would swap the ECM with another and see if that helps.

Code 224 flat out is "Internal ECM problem"

Auto ignition temperatures:

Gasoline: ~500*F
Diesel:...... 410*F (WD-40 is close to this figure)
Ether:....... 320*F

If the engine is pumping air and compressing it to normal pressures, it will easily start on ether (and a host of other shop chemicals).
