No good with late D1's , the immobiliser is built into the alarm module which makes it hard to bypass.

If you read the article, It explains where the alarm module is located and why they play up. If you do a search in Google, you will find heaps of info on how to bypass the alarm/immobiliser. You can even buy a bypass plug from eBay. http://pages.ebay.com/link/?nav=item...d=161586937300

That one on eBay is the spider bypass and I recently bought one from the local LR stealer for about $11 bucks

Hey just trying to help. If you have already managed to bypass it with a switch, id just look into making it more permanent by switching the glow relay and pump stop from the key and be done with it.

I know , i have exhausted all avenues apart from replacing the alarm module.

Ah that explains why I have a switch that (de)activates the fuel solenoid.

I had thought it was the last owners effort at installing a security/kill. He must have also had alarm/immobiliser problems. It seems a reliable workaround thus far.
