Just did some work on the car -- replacing thrust washers and rear main
seal.  Took engine out to do repairs as the thrust washers are pinned in.
Removed the drive unit and pi assembly, but did not remove head or timing
cover .  Put engine on a stand upside down.  Put all back together,
installed everything.  Engine would not start.  Timing correct.  Valve
timing correct.  Checked injectors, number two was leaking all the time
even when the fuel pump was on, even with no engine rotation/starting
attempt.  Couple other injectors were not injecting at all and a couple
were spraying fine.  Ig removed number two banjo bolt and replaced the two
o-rings.  Reinstalled.  Checked injectors and now none were spraying -- was
not even any pulsing in the lines.

Removed PI unit and disassembled the metering unit.  Movable stop came out
fine, shuttle and fixed stop did not.  Removed number one injector hose
inlet and rotated the rotor till I could see the hole.  Blew in some
compressed air and the movable stop came out.  No shuttle.  Strange.
Removed the drive unit and holding plate and pushed the shuttle out.  I had
put the pieces together wrong at least two years ago -- do not know how the
car ever ran as well as it did!

Put the pieces back together correctly, reinstalled and tested.  Still no
pulsor gas.

Check fuel pressure -- good, checked to see gas was actually coming into
the metering unit -- good.  So now I am stumped -- what is keeping the unit
from functioning?
