Can you hear the fuel pump prime when turning on the ignition?
No nothing, and the fuel relee doesn't clikk inn, so no power to the fuelpump. 
By the way...I disconected the battery last evening and left it over night to reset ECU, but still the engine would not start..
Should hear (or feel) the Fuel Relay (one of the Purple ones) and the Throttle Body click on, with the first time with Ing key on. This is controled from the ECU from memory.
I had issues in the past with 2.6 and 3.2 refusing to start, especially when they have been stood for a while.
Check the following -
Good Battery Volts, specially when turning the engine over.
Good battery volts at the Purple relays.
Check the Earth strap on the ECU housing, if poss check any voltage difference between the ECU Earth point and the Battery Neg (0v), with a voltmeter, or use a jump lead between the ECU Earth and or Ov Chassis and Battery Neg.
Transponder Issues?, Cheek the chips are present in the Keys, another Key?, pull off, check and reconnect the blue Connecter of the Transponder module under the Ing Barrel.
Sometimes with Transponder issues, or when you have pulled things apart, you have to go though a recycle, so try this a couple of time in between attempted starting. Key out Ing., open drivers Door, close Door, lock, unlock, open door, close door, Key back in Ing to start.
Chris.
Edit, forgot to ask, any codes present, with a reader or peddle trick, any flashing EML or Spanner light with just the Ing on, any unusual clicking with the Ing on?
