Really .. I read a post about immobilisers on "prelude power" it said there was in 4g's..

Nope definitely not.

What's interesting therefore is... If yours does have an immobiliser fitted... How has it been starting all the time before, when you apparently haven't had the fob?

If you are ok with wires and a solder iron you can do it yourself. It took me about an hour to get my alarm/immodiliser out. One of the best things I ever did! The only major thing that is needed to be done is to re-join the big thick white ignition cable that is in the steering column.

Ok that's blown that idea away then

Yeah I ripped the Clifford system out of my crx and rewired it but if there's no fob and no chip and the things been starting fine for months without it im going back to an electrical fault, my bets on a relay which has shot itself..

Could the big main relay under the steering column cause this?

Could it be a knackered ignition switch?? My red BB4 has a broken ignition switch and so turning it to the 'on' position doesn't actually turn anything on other than anything on the 'accessory' position - turning it further to the 'start' position turns the starter over but as the main ignition isn't on the car won't start. It's had a separate switch and relay wired in for the ignition as a result which works fine but would probably cause an insurance company to have a jobby fit*.

It also had a drokked main relay (both the ignition and fuel pump circuit) - that caused the car to not start either, and it did produce the symptoms of an immobiliser being on (no fuel or spark).

I soldered the main relay and it's on my to-do list to replace the ignition switch, but the car never fails to start now.

*FWIW if there has been an immobiliser fitted to the car and you remove it, your insurer may void the theft part of your insurance policy - Direct Line wanted me to take my BB4 to a garage and get a letter from them confirming that I had a Thatcham cat 1 device fitted. I didn't want to pay a garage for this so they just advised that they couldn't provide theft cover as a result, due to their policy on underwriting imports

The mad thing is that the UKDM version probably wasn't immobiliser equipped, and I'm sure they'd provide the theft element of cover on a UKDM 4g no questions asked...

No.

As per my post on page 1

If you think there is an immobiliser fitted on the car and all the other checks I said to work through have been done and checked OK then I think I would remove the immobiliser next. Being left flat for ages can cause alarms/immobilisers to misbehave when fired up again (become active/lose settings etc.)
Although the fact that the starter motor won't turn from the ignition switch but will if hot wired suggests it could be either an ignition switch fault, insufficient power from whatever the car is being jumped with (what is being used/how?) Or an earth fault, as suggested before.
What has been checked/done in respect of earth's?

Well it's running again and as it turns out it has an aftermarket immobiliser which has now been bypassed... To be honest I didn't even know it was aftermarket as I never had any issues with her and never had the need to even go looking for stuff like that..

Anyway she's up and running and will now be stripped soon to be for sale

Haha... It's got some scratches down the lh side, the arches have had filler and paint due to rust but not the best job.. Ideal candidate for a re spray as there's no real nasty dents on her.. Rust wise the arches need doing properly and the rear ends of the sills need attention... I've seen and repaired much much worse though on my crx but I wanted to wait and get the lude done in the body shop properly...
