w7rren Posted March 29, 2009 Share Posted March 29, 2009 Does anyone know what the standard Rover imobiliser does on a 2005 EU3 K ?, its the key fob with 2 buttons type. Feeling ☹️ A week ago after the winter break started car just ran for 30 seconds, all fine. Disconnected battery using isolater switch.A habit. Just changed perished hoses for nice silicone ones. Reconnected battery. Went to start car to bleed air out, wouldn't start. Battery fine.Spins engine no probs. Spark at plugs...... plug checked wasn't wet Fuel pump seems to work. Step motor on inlet buzzes away. All wiring / plugs seperated, reconnected. All earth sound. Even went & bought a gallon of petrol to ensure enough fuel. I would like to test the imobiliser any ideas ? I am tempted to push it down the road to the local garage to have their diagnostic thingy plugged in just incase the ECU need resetting.

Mr Locust Posted March 29, 2009 Share Posted March 29, 2009 Sounds like the immobiliser is out of sync with the fob. Our academy car used to do it. When you turn the isolator back on press either of the buttons on the fob repeatedly. About five times or so from memory. There should be a clicking of relays and the fob and immobiliser will be resynchronised. Then press unlock as usual and Robert is a relative from your mother's family.

w7rren Posted March 29, 2009 Author Share Posted March 29, 2009 Thanks Ian, I will give it a try tomorrow..... (my car is not at the house at the moment). Any other ideas out there ? Does anyone know what part of the car the imobiliser affects ? Born again sevener 1st LAMBO back in 1971 my fun motors Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 29, 2009 Share Posted March 29, 2009 Think it involves the fuel pump. Link to comment Share on other sites More sharing options...
mav Posted March 29, 2009 Share Posted March 29, 2009 it also talks to the ecu. I'd go with Mr Locusts suggestion in the first instance Link to comment Share on other sites More sharing options...
Roger Ford Posted March 29, 2009 Share Posted March 29, 2009 Do you have a red light that blinks when the immobiliser is enabled? What's it doing? Link to comment Share on other sites More sharing options...
Stuart McGill Posted March 30, 2009 Share Posted March 30, 2009 Inertia switch? Link to comment Share on other sites More sharing options...
w7rren Posted March 30, 2009 Author Share Posted March 30, 2009 No luck, even tried spare blipper. Roger.. imobiliser dash light works as normal during when operating system. Stuart .. I assume inertia switch is o.k as pump starts up as ignition is turned on. Is the only way to test the imobiliser by trying another unit ? ( I actually did my apprenticiship as an auto electrician back in the 70s cars were simpler back then) Born again sevener 1st LAMBO back in 1971 my fun motors Link to comment Share on other sites More sharing options...
CharlesElliott Posted March 30, 2009 Share Posted March 30, 2009 So the light goes out? The immobiliser stops the fuel pump, so if that runs I'm not sure you have an immobiliser problem.

Mike Molloy Posted March 30, 2009 Share Posted March 30, 2009 The CCT LED is always the best guide as to what the immobiliser is doing. If you have pressed unlock on the fob (should hear relay click in the 5AS), turned Ignition on and the LED is OFF, then the immobiliser is disarmed and sending the correct MEMS code to the engine management unit. The immobiliser itself does not control the fuel pump or disable cranking. All it does (in the Caterham application) is transmit the MEMS code if correctly disarmed.

Rob Walker Posted March 30, 2009 Share Posted March 30, 2009 Sounds like the AICV is stuck open and allowing too much air through making the start up mixture weak. I have had this problem several times. Take the AICV too bits and clean it & ub with WD40. Rob Link to comment Share on other sites More sharing options...
w7rren Posted March 30, 2009 Author Share Posted March 30, 2009 OK, I have a on my face ! I called out the 'Auto Recovery' service that is provided by Footman James Insurance. He was keen to have a poke around, he prodded & poked the wiring connectors ( as I had done...... & it started !!! He did connect his battery as mine was flagging a bit that may have helped ? BUT my battery was fully charged at the begining of the problem . Thanks for your contributions to the thread .

w7rren Posted March 30, 2009 Author Share Posted March 30, 2009 Rob, just missed your post as I was typing. Where is the AICV situated, .....so that I can check it if it happens again. Cheers. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 30, 2009 Share Posted March 30, 2009 IACV - on top of engine - on air inlet - with wires going to it. See a photo on a recent thread ! edit - here it is - look half way down Angus's page for a piccie Edited by - Stationary M25 Traveller on 30 Mar 2009 20:59:52 Link to comment Share on other sites More sharing options...
