In theory, the Lucas injector pump is pretty simple.  I would think =
either the rotor is not turning or the shuttle is not moving.  I =
can=E2=80=99t think of why you get no fuel other than that.  To have all =
six nozzles plugged would be unlikely but not improbable if there is =
dirt in the lines.

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.

=20

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!

=20

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

=20

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?
