drug into shop tonight.
Maybe i was wrong about air in supply- now just has small bubble. fuel at #3 when cranking.
pulled turbo boot, checked shutdown thing is open
monkeyed with stuff for about 2 hours in the heated shop, gave it one last foot to floor and long crank- fired.
runs fine, 10 mile test drive.
guessing water in fuel broke free, i put some diesel gel treatment in it. bah.
annoying!
