I think this is the one. From this link: http://www.freel2.com/gallery/displayimage.php?album=255&pos=2

It looks like six wires. I guess:

ACCL SUP: 5V
ACCL GND: 0V
ACCL SIG: variable between 0-5V, according to position.

Check these at the pedal and at the module, before and after the fault happens.

The other wires look like a secondary pot or signal to the ECM. The pruple one should have battery voltage.
 
There's two wiring libraries kicking around the Internet LH & RHD I think the one you found is LHD colour coding looks different.
I discovered this when checking the fuel sender wiring the grounds where on different locations on the CEM for LHD
 
Just had a little lookey with the torch and there appears to be a damaged wire under the steering column next to the rake adjuster bare wire showing. Don't
Know if it could be causing the problem unless its going to the steering sensor?Will look at that tomorrow and report back
 
Sorry for delay
On tickover
Acc pedal results before fault after
BCM
Signal yellow/orange 0.5 0.1
(No range after fault)
Supply green/orange 5.1 0.1
Fused supply purple 7.7 7.7

ECM
Blue/white 1.0 1.0
(Still has range after fault)

Is working okay maybe when it goes into limp bcm kills the voltage at supply so then controlled by the ecm.....
 
Trying to find where it comes from but it' more than likely the engine bay fuse box.
Maybe there's some corrosion there.
I'm going to check the voltage at the in tank fuel pump see what' there.
I might just be a bunch of supply voltage problems......
 
Could be that the fuel pump relay is open or knackerd.

Whereabouts? The fuel tank unit has six wires, according to that diagram, p25.

The live and ground go to the middle 2 pins I've got 0 volts at the positie
Brown and yellow. Tried grounding on the chassis still nothing.
Would the relay work if the voltage is low?

The fuel pump won’t be energised unless in prime mode or the engine is running, I guess.
 
I mean these wires:

Remote and pump sender.

I’d also trace back that purple wire for the throttle pot and see if you can find battery voltage somewhere up the line.
 
I'l give it a test with engine running.
What do you think about maybe replacing the fuse box. I guess if I get a good second hand one I've not wasted too much money.
I can test some voltages at the fuses on the bcm
And it looks like it' all feed from engine fuse box some on relays.
 
Okay all the fuses on the bcm are 12 volts so am I right in saying it's either losing volts through the bcm or there's damage to the loom?
 
A lot of pedals appear to use 5v but I need to find out for sure. So maybe another fault needs to be looked into.
