1999 MGF in Australia is not turning over after a battery disconnection (new dry suspension). Key fobs lock and unlock the car and activate/deactivate the alarm. But when I turn key to start, all the pretty lights come on but silence when I try to start it.
Tried the 4 digit manual override (door key turns) multiple times to no effect.
If you have done the key unlocking sequence successfully, the alarm LED will have stopped flashing. The immobiliser is off and your problem is electrical but not in the immobiliser.
If it is still flashing, then the contacts in the door lock are likely to be dirty and missing count instructions but the immobiliser is still on and so you won't be able to start the engine.
Hi all, thanks for your replies. After some professional attention it turned out to be a loose ECU connector... not obvious as they were all plugged in but disconnection was concealed by the rubber seals. Rather anticlimactic but at least not blown electronics!
