Car broke down suddenly after perfect running history. AA man spent pointless 3/4 hour cranking it over and pouring more and more diesel into the fuel filter, then called recovery. He ignored all the checks I had carried out prior to his arrival and used NO diagnostics.

Engine management light was on. Diagnostics showed 'critical systems failure-fuel injection pump module replace-fuel quantity control system failure'.Module is integrated with injection pump. Testing showed 2 pins on pump connector gone to earth. Thus injection pump replaced ()
All belts replaced, engine timed up (dial gauges etc)Fault codes cleared.

When cranking, all warning and check lights go out normally. Heater plugs working correctly. Pump is primed.After cranking for approx. 4 seconds,the engine management light comes on continually. The engine does not start. No fuel is reaching the injectors.
A new fault code appears 'engine RPM signal from ECU missing'.

I have checked all sensors for resistances and voltages. I have carried out continuity checks on all the engine ECU harness connections. I have sent away the engine ECU for testing-'no faults found'.
The keys open the car and disarm the alarm correcly

I am a qualified vehicle technician, I teach vehicle studies at an FE college and have access to diagnostic equipment (Snap-On Heritage)however......

Does somebody KNOW what is wrong here? What have I missed? Any assistance would be gratefully recieved.
The caris a 2000 Zafira 2.2Dti turbo diesel.
