Turns over but won't start

[Iowa Hick]

So yesterday morning when I started my truck it started just fine, then when I went to back out it went a couple feet and died and wouldn't restart. It turns over just fine, but won't fire.

Here's what I know so far:
2001 F250 with 7.3 Powerstroke
I changed the Cam sensor to no effect
I've checked every fuse in the truck and found none blown
When I turn the truck over the starter gets it up to 170 RPM
Changed the fuel filter to no effect
When I drain the fuel bowl it fills right back up with the key on
Unplugged the oil pressure sensor and tried to start the truck to no effect
When I turn the truck over for an extended amount of time the "Low Fuel" light flashes
I have not check the batteries, but the voltage on them reads around 10.1 at this point (it was over 12 when the issue started)

That's all I can think of so far. I'm guessing my problem is electrical, but I'm having trouble pinning it down. Anybody have any suggestions for other things to check?

Thanks,
Jake

Ignition switch? Where you insert the key is just a cylinder. When you turn it, it pushes a rod down the column to the actual ignition switch. It is a white box on the column. 2 screws and one plug. about 15.oo for a new one.

Try to unplug the ICP. If it starts with the ICP out, you need a new one.

He said he already unplugged the ICP. I would say your batteries are shot. 10.1 volt is way to low. The truck has to seen , either 200 or 250 rpm to kick it over. I would replace the batteries are report back.

Funny, mine never registers rpms when cranking. In a start or no start situation

New to diesels. What is the ICP and where is it?
Thanks

Injection Control Pressure (sensor) not sure where, is it the one on the top by the hpop and drive side? or is that the IPR?

You will have to charge the batteries to go farther in your trouble shooting
