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.

Subject: [Fot] Need help with PI -- no fuel to injectors
=20
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?
