helloo, just wondering if anyone would know...

basically done a cossie management conversion but cut out the old parts of the loom which the old ignition and fuel ECU were connected to.

anyway, now my immobiliser is playing up,

alarm and central locking works fine etc, but the immobiliser comes on when the ignition is turned on.

got all the wires connected right on the battery from before when it was working fine.

however when i chopped out the old part of the loom, 3 little brown earth cables were removed from loom which connected directly to battery.

could it be an earthing issue with the immobiliser causing it to come on with ignition?

also my fuel pump has decided to stop working, no power going to the pump at all. was thinking it could be todo with immobiliser?

cheers
