Seems there is plenty of battery power, fails to turn over, is it the starter motor and if so an easy cure?
Starter Motor? .... RS not starting
- Thread starter carreraboy
- Start date
Check the usual favourites, DME relay then the ground/earth strap.

Try the simple things 1st Des.
Swap the battery with a known good one, this is what I had beginning of the year. It looked good and didn't dim down when tried the starter but it didn't have the juice to start it.
Next the DME relay as Geoff suggested, get a good one as a spare for the glove box.
You can check if it's an earth strap by piggy backing using jumper cables. There's the one from the battery to chassis. the last would be the starter motor earth strap.
Next would be checking the ignition switch by shorting out the appropriate connections to prove it's supplying juice to the starter relay, but I guess by then you'll have it in a garage.

Des,
Other than possible suggestions listed above, to add to the mix, it could be an immobilser issue, depending on type fitted.
Is it a new-ish battery in the unit you press to de activate?
If you have ignition on, immobilser primed to start and it bump starts, it could be starter...at least that would show if power is getting to the vital ignition parts.
I think earth cable already mentioned is first to tick off of the list and cheap and easy to resolve.

More than likely starter solenoid sticking. Put in gear, rock car back and forth. This usually un jams solenoid if only just started being an issue. Put in neutral, try a restart. Repeat if needed. Jump battery may help provide the extra juice as well. This is assuming starter is not turning over. I don't think it's DME relay as this runs fuel pump. If it turns over but doesn't start then yes suspect DME relay or fuel pump.
My similar problem was cured a couple of years ago with a starter motor re-furb. Apparently they are prone to seizing over time with clutch dust! The re-con motor worked albeit I could have bought a new Bosch one for less, oh well.
Thanks again .... gloves on in the morning, could even be the isolator wiring, this was such a simple fix on my N-Gt a simple crimp but will investigate all above, [8|]
Turned out knackered battery, just MOT'd no advisories[]
Forgot to say, tried rocking the car Paul, my God it's solid, despite the help of others it just stood solid, KWV-3?

From this experience of rocking your RS, could be born a new sport, how hard is your suspension. So just imagine a testing team going round a display rocking and rolling[]

Hi Des, glad you got it sorted. You must have misunderstood the rocking backwards and forwards comment. Maybe didn't describe it properly. If the starter ever jams you put the car in gear, handbrake off and push it back and forth. This will turn engine back an forth which will release the starter motor from being engaged / jammed in starter ring gear on the flywheel. Your suspension is not relevant.
Yes, always try and entertain you technical guys, I did actually try this, and handbrake never on by the way, a minor bump also with courtesy of the concierge, light car to push on your own on the flat[]
