Have you tried the cutout switch in the boot under the spare wheel? Press it in it might have poped out this happens all the time. Cheers.

If it doesn't run/try on easy start you know it's not a fuelling issue, that leaves sparks to look at.

ignition amp ? had the same problem with mine years ago after my dad was cleaning under the bonnet. must of knocked the ignition amp and there was no spark. took a few days of messing about until i unplugged it and plugged it in again and fired straight up.

Hi guys the motor tech has been today checked a few things and recons its the ignition amp and the group a coil so will try that il keep you guys updated thanks.

the chances of the coil and amp failing at the same time are remote,
its more likely to be the crank sensor or the phase sensor in the dizzy.

Cosworth Lad

yes but theres no power going to the pump

The sensor in the boot will cause the two not to work too. Exactly the same happened to my saph try crossing the wires that go to it. You could even push a Stanley blade into the two to make a connection and get someone to turn the key

Cosworth Lad

Thanks pal will try that today but the tech has even checked the power in that too theres nothing he recons the coil is shorting and thats messed the amp up so he said try changing both his 80% shore its these 2 things and said there cheap to change and will go from there will keep you guys updated Thanks lads/lasses.

My mate had the same problem with his 4x4 and it turned out to be a fuse which is tucked up behind the dash (part of the original wiring) changed it and it fired up straight away! Can't remember if it was on the driver or passenger side though, worth checking!

Cosworth Lad

Have tried them fuses thanks seems as though the imobeliser is messing about sigma typical will keep updated thanks any ideas?Have tried the ecu in my mates car works fine so did the ignition amp?

Cosworth Lad

theres no power going in to the ecu but theres power going from the ignition barrel?

Check/clean the the loom connectors behind the battery, one of them has the ignition live in it, black wire I think.

Mine was similar when I fitted a new loom, turned out to be a loose pin on the ignition live.

Cosworth Lad

thanks bud did that today no diff?

Cosworth Lad

guys crank/phase/dizzy shouldnt make any diffrence to the power to ecu should they?

Have a look through these

I'd check the wiring to the relays before messing with the immobiliser.

The inertia CUTOUT switch on a cosworth 4x4 is behind the kick panel in the drivers side footwell and you need a Philips screw driver to remove the panel

Maybe ford always new we would have a toolbox in the CAR

Cosworth Lad

Tried all that and couldent find no switch on the drivers side kick panel/Any ideas?

I've got a similar problem with mine. Mine will only run with the phase sensor disconnected. Unplug yours and see if she starts

cossie350

Mine is in the spare wheel well............

Cosworth Lad

Thanks will try that tommorow

Cosworth Lad

bump any other ideas?

Cosworth Lad

Sorted got it started/The 4x4s come with an aircon option and come with aircon going into the loom under the turbo that wire melted and blew the ford alarm that imobelised the car so thanks to GARY RS CLASSICS iv got the alarm and thanks guys for your help.
