Hi everyone, i have a mk2 rev1 turbo and for some reason shes just stopped turning over, no noise from the starter motor, i had this checked out and all seems fine as well as the solenoid and the main power cable,

all the lights come on the dash board which should come on, i was thinking it had something to do with the really old flashpoint alarm/immboliser, so i got this removed but still no good, has anyone got any ideas or could it possibly be my other immboliser thats now stopping it? Also if i put my keys in the ignition and unplug the plug near my ecu and use a piece of wire then the car starts fine,once the car is started its fine.

Any help would be great
Thanks
