Good day colleagues 

Help Please 
Did you have these symptoms


Ford Edge 2008 will not start, there is no spark

When I turn on the ignition, fuel pump shakes once, you turn the starter turns but the RPM do not rise,
Scanner also showing that there is no symptoms of crankshaft signals, 
But other parametres of other sensors Like engine coolant, air temperature , the gas pedal, electronic throttle control, mass air flow sensor is OK

Wiring from crankshaft sensor to PCM is OK. 
Resistance of crankshaft sensor is also OK. 

PCM has a one fault ---- P1000: FF ----- Cant understand what is this fault 
(Immo related fault or Other Computer faults does not have, )


I wanted to check if PCM is detecting disconnected sensors and then removed the crankshaft sensor, the mass air flow sensor and the oxygen sensor. no fault code appears in ECU ---

What might be problem?

Might be PCM defective?  or something inside PCM broken or burnt which controls some function or speciallt crankshaft sensor

when I removed sensor it has small metal pieces, i cleaned and fixed it back and then connected 2 wires and voltmets on 2V range to check if anything will appare, when I cranck startor voltmeter is showing small amount voltages, I think it tells that us its life, is not it?

another thing why I surprised, why when I remove 3-4 sensors of engine, PCM is not sensing if sensor is there or no?
OR will it start sensing after engine starts
