Help" Engine quit

[dhilke5]

Can some one let me know what the symptoms are when the crankshaft postion sensor goes out. After I changed fuel tank over it went about a mile and started slowing down and running rough so I shut it off. When i tried to recrank, is wasn't spinning freely, like a gas engine when flooded. When I tried to drain the fuel bowl, it had lots of air pressure instead of fuel running out.

You may have a broken fuel line to the tank that you switched to.
Try switching back and priming.
When the CPS goes it would shut the truck down. And you would not have air.
Sounds to me like something physical not electrical.

Sounds like it ran outta fuel to me too, look for anything dripping under it, I dumped a full tank when my high pressure fuel line went

There is no crank position sensor. The CPS is the cam position sensor. And since the fuel system is mechanical, it's totally unrelated. What's the fuel level in the selected tank? Did you try switching back?
