DT466E Rebuilt. Ran, then no start.

If the pickup tube is cracked, it is an easy visual.

 

Welcome to the joys of our world! LOL! Yes, the pan is somewhat trapped by the tube. We have to unbolt the pan and sorta let it just rest on the axle and then unbolt the pick up tube, let it fall into the pan, and then take everything out that way. Some trucks you can jack up the chassis enough so the steer axle is hanging by the springs, then support the chassis, and use bottle jacks to force down the steer springs to gain more clearance, but once you mess with that, it is just faster and easier to work with the small gap you have between the pan and block to get the tube unbolted.
