Pump not priming -circuit control relay?

Does anyone know if the pump prime is controlled by the 'circuit control' relay?
I'm being a bit lazy really, but a quick cursory glance at the wiring diagrams I've got on my phone and I can't find the right one.
Thanks people.
 
Looking at the wiring diagram I can’t see anywhere saying circuit control relay. All the relays I can see on the circuit are the main relay, fuel pump relay, fuel pump resistor&relay. As for fuses the 30a egi fuse under the bonnet, and the 20a fuel pump fuse in the footwell driver side.

The current seems to travel through the main relay and fuel pump relay first so possibly check these 2 out first. They are both under the bonnet. Also make sure the egi and fuel pump fuses are ok.
 
You tried priming direct from diagnostics box si? Can't remember which they are gnd and tgn or something like that I think! Maybe worth a try to see if the pump is good?
 
Cheers rehab. Unfortunately my wiring is a little, umm, unique, so I think I may have to dive a bit deeper.
I couldn't see the circuit control one either, but that's definitely what it's labeled!

Tada!
That's the box that's normally found in the bay, btw
 
hmmmm ok so circuit control relay and main fuel pump relay should be next to each other. But your missing the circuit control one which I assume is the main relay which is what it’s called in the fsm :/
 
I'm not sure, the car's been laid up for 3 years, I suspect I may have implemented a rudimentary additional security measure... :/

...like removing the cricuit control relay so it won't start?

Maybe try jumping the pins where that relay should be.
 
With an awful lot of rewiring! Which is why the original question possibly isn't as straightforward as it seems. However, I'm going after the way wins first! Now. Time to turn the garage upside down...
Could anyone do me a massive favour and let me know what color that relay is?
