Happy New Year and unhappy no start :-(

It’s been stood in the garage for 5 months on a battery conditioner. Rolled it out to start it and warm it through and no go. First time it’s ever done that as always has started first turn of the key. Not getting the fuel pump whir, and oddly the speedo needle spins round and round when ignition turned to II (start) .... The battery is fine putting out 13.1v on a simple tester.

I’m thinking it might be a relay perhaps? Where should I look / check first?

Thanks, Andrew.

Thanks GreenV8S.

I think I’ll check the Cobra immobiliser out too, as you say it could be related to that.

...if not replaced already, then your yellow connector could have finally burned out - take of the steering cowling and look for the big yellow connector...pull it apart and marvel at the chard remains...will lead to no ignition.

Thanks AutoAndy.

Is the “Yellow Connector” easy to replace? I’m not familiar with it (clearly a newbie and/or up until 2019 had the most reliable S2 in the UK lol). Can it degrade stood still in a garage?
Anyone got any piccies handy of it?

Googled it. I now see via the “Yellow Connector” thread on here.

If it’s burnt out I’ll replace it with electrical block connector, assuming that’s a safe fix?

Hi all,

So removed my steering cowl to find that I don’t have a big yellow connector lol. It must have burnt out a long time ago for a previous owner and had since been rewired. I wiggled the wiring around with the car in the garage and on the battery conditioner and started to get the fuel pump priming so peeled back the electrical tape to find no signs of burning or deterioration....
At that point I’d concluded that the rewire may still be the issue and was preparing to cut through and chocblock to test further, however the terrible lighting in my garage meant I needed to disconnect the battery conditioner and push it out into daylight.
I gave it one last try outside and now not even the fuel pump was priming which made my think could it still be the battery? Even though it showed 13v on the tester when I checked it. So I threw my spare battery on and hey presto, fired up perfectly first turn.
I should never have doubted it, it’s not missed a beat nor broken down in the 4 years I’ve owned it. Instead it was the 6 year old crappy Exide battery laugh

Anyway thank you all for the advice, and first rule of the S series is never doubt the S series rofl
