Something weird going on there. Fuel to the filter should also mean fuel to the accumulator, and unless there is a blockage somewhere - then the fuel should also be reaching the fuel distrubutor.
Just crossed my mind: How did you get the fuel pumps to activate? Followed 930Rocket's directions? I'm wondering if the micro switch that connected directly to the metering plate control arm is toast. With your intercooler off and the ignition switch on, the pumps will not run unless you depress the metering plate arm (just a couple mm's is all it takes)...basically manually mimic the action of air being pulled in when you crank the engine. If the switch is bad = no fuel when cranking.

Or, perhaps a failure of the pressure regulating mechanism within the fuel distributor (I THINK it's behind one of the banjo bolts...see the link below). Unfortunately I don't remember much about it's function without taking the time to re-read my Bosch CIS manual.
