in need of some serious wisdom

ok so it happened like this my 94 3.9 v8 disco has been ok till about a week ago when the revo and speedo stopped working plus the battery light was on whilst working after a few miles they started up once home tryed to lock the motor and the fob doesnt work so tryed my spare one no joy a few days later still running fine get back home try the fob maybe 10 times and the doors lock think nothing more till i try to unlock the next day and none of fobs work can still get in via the key but alarm is going and immobiliser wont let me fire it up after much stress and slamming of doors and bonnet find out about the alarm ecu (17vt on this motor) so i unplugged the bugger over night plugged it back in next day and voila fobs work ignition works runs fine big smug grin 4 hrs later try to start her up nothing the fobs still working central locking all that crap turn key and not a sausage just silence now ive been scratching my head all day which im sure has lost some fluff by now and cant figure anything out tryed charging the battery over night under advice from another post but still nothing getting it towed to the garage is not a route i want to take any enlightenment would be received with many thanks

try a new battery

Hi mate
Have you looked at the ignition wires (behind the steering binnacle) and see if all is looking ok. It just sounds like there mite be a loose/dry contact or the multi plug might be loose or burnt. Hope this helps....

Check your voltage some ECU's drop out if the voltage goes below 11 volts

i shall take a look at that first thing as im checking the alarm ecu for dry contacts aswell nice one!

You can lead a horse to water but a pencil must be lead, a wise man once said.

Sorry no help at all

ok so i think ive narrowed it down to the alarm ecu more so the immobiliser element of it as ive for a second time left it unplugged for a day or two and upon plugging back in she fires up first time so i had a thought that if i tried locking and unlocking on the fob it may not fire up which it didnt but the alarm and locking work fine so its a case that the immobiliser does not turn off after being activated ive checked inside the box for dry contacts but cant see anything so it must just be a faulty part is there a way of getting rid of the thing altogether as im not that fussed about having it there

Just a thought might be the spider? there is an over ride on e-bay....
