Check the condition of suction line from steel line to hand pump, and
the hand pump itself. Both deteriorate, and if they leak, will cause
the lift pump to pull in air instead of fuel. The result is a no-
start condtion.
Operate the hand pump while watching the new, clean in-line filter. If
there is a constant stream of large air bubbles, replace the line. If
the hand pump is the old style red knob you screw down to seal and it
pukes diesel fuel when operated, the plunger is shot, replace it with
the new style sealed "thumb" pump. If the pump it bad, so are the line.
Also, if the pump plunger doesn't come up by itself, likely the tank
screen is plugged. A temporary fix is to GENTLY blow some compressed
air down the line into the tank with the filler cap OFF --- you don't
want to blow the tank apart!
Once you get fuel up to the lift pump, crack the bolt on the main
filter and pump until there is no more air coming out (this takes a
while), and then close it up. Pump the hand pump until you hear fuel
hissing through the injection pump (also take a long time!), then crack
the injection line cap nuts on the injectors and crank until only fuel
comes out with the accelerator floored. Tighten the cap nuts, run the
GP, and then crank, it should start fairly quickly.
Note that you may need to charge the battery a couple times once you've
run the IP dry, and don't run the starter more than 20 or 30 seconds
without at least a couple minutes cool-down time -- you don't want to
roast a starter, too.
When you get fuel delivery, you will get white "smoke" -- actually
atomized fuel -- out the back.
I would also verify that the stop linkage is up and that the vac servo
isn't stuck.
