Before you dig too deeply into the Fuel system, you need to see whether the Ignition is producing spark at the plugs.

I know 240s better than the 700 series, but ALL Bosch FI systems will not deliver any Fuel if it can't be ignited. The FI ECU MUST see timing pulses from the Ignition before it will "wake up".

This is a built in safety feature — not to pump fuel to a dead engine, as in the case of an accident.
