Car won't start! Help needed.

Hi all,

 

Ive just come back to my car and it won't start! My voltmeter is showing 12.5 and when I try to start the dash hand brake light comes on and it makes the usual whirring noise. There is a click when pressing the starter, but other than that nothing! I'm outside a Halfords, but I would be surprised if they could do anything. 

 

Any ideas would be greatly received

Any recent work done on it? Has it been drowned recently?

That's 12.5 V across the battery at rest? What does it drop to as you try to start?

Is that the ignition warning light? Does it come on as usual when you turn the key?

Reset inertia switch.

Cycle immobiliser.

Inspect and wiggle the relevant cables including battery and starter and earths including the engine block.

Check ECU fuse.

It had a new banner battery, but that was back in March. I've had no battery issues (always remove the isolator key) and the car felt absolutely fine earlier. It also feels fine when you put the ignition on, it just doesn't do anything when you press the starter, the volts don't change either.

I've tried fiddling with the wiring, but I think everything is in place.

Put car in gear,handbrake off and rock the car left to right, incase starter motor stuck and this might free it.

I've just tried that and nothing. I think the battery is ok, everything seems normal until you actually press the starter!

Click but no drop in volts... so the starter solenoid isn't throwing.

Check the starter relay. If you're not sure which it is (and there are ≥ 3 layouts on Sigmas) can you add a photo. (Being outside Halfords could be about to become relevant... )

Do the lights dim when you try to start it.

Nothing dims, nothing changes. The volts are dropping over time a bit, but I think that's because I keep trying to start it.

The lights should dim ,swap the relays around, them 6 are the same.
