Since the car sat for a long time (previous post), I would do a quick check to see if the airflow plate is free to move (engine off).

If it is free, run the pumps (jumper fuses 7 and 4 -- Left side contacts best).

Then see if you can depress the airflow plate with moderate pressure. It must deflect a little (as with cranking airflow) before the FD will meter fuel to the injectors.

If it feels like it's locked, it could be excessive Control Pressure on the control plunger, due to a blocked fuel return at the CPR/WUR.

But with any Kjet, a fuel pressure test as Chris suggests is probably the very best 1st step, so you know your basic Control and System pressures are correct at "square one".
