Fuel pressure?
If you take out stepper and power up truck, it should move in/out on its own. Don't try to force it. Just clean with squirts of carb cleaner, and the bore it fits into. It is a computer controlled 200 step (or 180, depending on version) vacuum leak.
No crank just turn key till power comes on?(fuel pump kicks on ect..)
After you do a major job you need to recheck your steps on reassembly. I of all people know this (re: stall post). If it ran before you took it apart there is a good chance you have a simple problem.



Lets see if the junk yard has one I can nab. I'm not paying $140!
