Help scorpio won`t start

Hi all got up this morning to find the thing won`t start? 
There is fuel but no spark at the plugs  now i have checked the resistance of the cam sensor (365 ohms) and the crank sensor (445 ohms) are these normal?. Also there is 12V at both coil packs. (all the wiring on the loom has been replaced with new cable and plugs).
Now someone said it could be the immobiliser or the main ecu any help will be greatly received

The first thing to do is charge the battery or jump start it. These cars require a large amount of power to start them even if they do 'turn over'. Do the 'needles' on the dash dials fly round ?. That is a sure sign of a failing battery. Is there any sign of oil from the steering reservoir on the large connector beneath it bolted on to the inner wing. This unit is held together by a bolt so it is easy to identify. Check it for corrosion if that seems a likely cause.
Just got your update. If it shows no faults that usually indicates a wiring type problem. ie; not a defective sensor, if I understand the system correctly.

Hi to explain better.
When i got in the car this morning it would not start, it turns over fine and there is fuel to the injectors but no spark at the plugs!
OBD says no fault codes
All wires connected and checked
Plugs only two weeks old
so no idea why no spark?
cheers

With all the rain we've had recently, then is it possible that the battery side fusebox has got damp or water has dripped through the bulkhead & got on the PCM ?

Do you have the battery cover fitted? and are the drain holes in the bulkhead clear. Is the carpet wet in the passenger footwell below the glove box?. This might help.

Check fuses F31, F34, F37
www.fordscorpio.co.uk/images/battery_fusebox.gif
Make sure the multiplug on the EDIS unit behind the o/s headlight bolted to the wing is on ok, you can just see it below the front of the coolant reservoir if you pull back the screenwash reservoir

Check fuses 16 and 17 too
http://www.fordscorpio.co.uk/images/central_fusebox.gif
And try locking the car then unlocking it, incase your alarm is operating but the horn has been disconnected.
Using the right keys?? (I have done this)

Read my earlier reply (2) re the connector on the inner wing and have a look at THIS I think this is the EDIS and if you look at the diagram and the table you will see that the two coil packs are controlled via this unit.

It may look ok but you may have corrosion on the pins inside. Just separate the unit and check it out and perhaps use a drop of WD40 if it appears necessary.
