Fuel pump not running

[Radek]

Mystery solved:  ground on the FP was bad.  Now it's the question of fixing 
the harness - fuel pump connectors are quite special and I'm not sure where 
to find replacements.  If I have to, I'll solder wire directly to the 
terminal.
Car seems to be idling fine with the FP hot wired, didn't test it on the 
road.  Once I fix the pump wiring, will road test (car is temporarily 
without Fuel Pressure Accumulator) for drivability issues.
Cheers;

Radek.
