Hi I've recently acquired a 1995 16v non turbo and it wont start with any of the 3 keys I have but (does crank over), I tried the battery fix but I believe the immobiliser is completely screwed. In the owners handbook it says to start the emergency start procedure wait for injector light to come on and pretty much it doesn't come on at all, did have a look to see if it was the bulb but no it was fine I've scrolled though the forum to see if i could find the answer but came up short.
I would greatly appreciate if someone help/point me in the right direction as id like to remove the immobiliser permanently

Hey 386ka I haven't seen another 16v driving about in quite some time their quite rare these days Well the CODE light stays on and the injector light doesn't come on at all, I was told by the pervious owner that it was parked up for 6 months and she went to start it and nothing would happen and it sat there for the next 5 years, so it could also be an ECU issue

Well after seeing if it was just a plug not done up correctly I came up short, I went over the whole engine bay checking if all the connectors where done up/connected and still no fire only spin So I think its time to get the ecu immobiliser and key reprogramed But I don't know who to go to for this

You might want to try GrahamL on the Forum, he has fixed my corrupted CODE box (20vt) and it might be similar for 16v

The 16v ECU stores the immobiliser codes differently so not sure I can do anything with it. I had a 16vt firmware image with the immobiliser disabled but unfortunately I never saw a 16v na equivalent. Don't think I ever even saw a dump of the 16v na firmware at all.
However, it sounds more like an ECU problem than an immobiliser problem.
At ignition on the ECU and immobiliser should power up and switch on their respective dash lights. Then they attempt to communicate with each other and confirm that they are connected to the correct partner unit and if so will then switch off their own dash light.
So the fact you have no ECU light but have the code light strongly suggests a problem with the ECU not powering up along with the immobiliser switching on its light as expected but not switching it off as it can't talk to the ECU, again suggesting an ECU rather than immobiliser issue.
I don't know the 16v fuses but on the 20v there's en EFI maxi fuse for the ECU so check for something similar, or possibly broken wiring or bad connection on main ECU plug.

Neil, it was actually a dead 15?amp fuse but I forget where James said it was. Near the battery I think, anyway so no power going to the immobiliser.

We must all do our part for the planet. I unplugged a row of electric cars that nobody was using.
