It might look fine, but could still be nackered. Replace the coilpack, HT Leads and sparks. Will cost you about £80.

would check feed to coil as a first check , pin 2 the centre one should have 12v to it , I made a loom up so I could check and take the earthing of the coil away from ecu control , if you have feed to pin 2 then check continuity through the coil from pin 2 to 1 and from 2 to 3 , these should both be 0.5 ohms , this is the primary resistance , then check the secondary coil resistance by disconnecting all plug leads and measuring between 1 and 4 then 2 and 3 , both these should be around 10 Kohms , let us know what you find

sirloveyou

right there is power at the coil
but still no spark and I cant hear the fuel pump kick in !
Also there is no led by the clock no flash or anything but the ecu has been tested
im pulling my hair out now !

The LED by the clock should flash to indicate the immobiliser is armed, then when the ignition is switched on it illuminate solid for a second or 2 then extinguish completly thus showing the immobiliser has disarmed.

well I have nothing it dont flash and it dosent come on when I turn the key ?
is there anyway of bypassing the immobiliser ?

Not easily, far better off getting it working otherwise you are compromising the security of the car.
