Frogman Posted June 3, 2021 Share Posted June 3, 2021 Looking for some guidance from the wise amongst you. Isolator switch on, ignition on, fuel pump activates lights go on and nothing on push button or ignition key start, no click, nothing. I have loosened, cleaned and WD40ed the terminals on the starter motor and it seems to work but I am concerned it may fail again whilst away for a weekend. Two days ago it pissed down and the car was thoroughly soaked on a 3 hour drive, it has a new Lithium and when it does turn over it does so quickly and fires and starts immediately. Car is a 260CSR 2007. Should I be worried about starter motor degradation or should I be looking elsewhere? Link to comment Share on other sites More sharing options...
John Vine Posted June 3, 2021 Share Posted June 3, 2021 I don't know how different the CSR starting sequence is compared to an R400D, but my first thought was immobiliser. Is this deactivating correctly? Is the fob being recognized? (Indeed, does the CSR have an immobiliser fob?) Does the immobiliser flashing rate change as you bring the fob close to the antenna?JV Link to comment Share on other sites More sharing options...
7 wonders of the world Posted June 3, 2021 Share Posted June 3, 2021 Has it only misbehaved since it endured the significant 3 hr wash....? Link to comment Share on other sites More sharing options...
Frogman Posted June 4, 2021 Author Share Posted June 4, 2021 I am pretty sure it is not the immobiliser but happy to be told otherwise and yes the overly damp conditions do appear to have provoked this misbehaviour. Link to comment Share on other sites More sharing options...
SM25T Posted June 4, 2021 Share Posted June 4, 2021 Does the immobiliser prevent cranking of the starter on this model ? Link to comment Share on other sites More sharing options...
Frogman Posted June 5, 2021 Author Share Posted June 5, 2021 Having said it wasn't the immobiliser and thinking about it some more it would seem that it may well have been. A bit of careful tag waggling appears to have restored reliability. Thanks all. Link to comment Share on other sites More sharing options...

krisfl Posted October 4, 2021 Share Posted October 4, 2021 Morning all.I had this exact issue described in the initial post. Adding my solution here too incase it helps someone else in the future. Looks like your issues were solved @frogman - "tag waggling"...For ref: 2016, Sigma Ti-VCT car with stock electrics, including the tag/fob immobilizers and ubiquitous red starter button...My symptoms: ignition on, fuel pump primes, immobilizer LED blinks fast, waggle tag till immobilizer clicks, Red LED goes out - should be good to go - press the red button and silence. No solenoid click, no crank nothing... It went through a few weeks doing this intermittently, some times taking 3/4 or even 5 goes before everything magically comes to life and it fires. Then it just stopped starting at all - fortunately in my garage, rather than mid blat. Checked all the under bonnet connections, clean and tightened etc. Nothing worked.Q much searching on here, and some kindly provided wiring diagrams from ever the helpful membership (you're all legends). Then an evening spent with feet up the roll bar and head under the dash with diagram in hand. Multi Meter generally getting tangled. Realized that all the dash gauges and switches all come back to a single main earth by the fuse box. Located and wiggled the earth. It proved to be "comically loose". Tightened down with a new nylock nut from the "emergency nut box"Start issues "suddenly" disappear, all rocker switches now glow strongly too...and my oil pressure gauge now reads more strongly... something I previously had in the TADTS pile. Hope this helps someone!BestKris Link to comment Share on other sites More sharing options...
Ed White Posted October 4, 2021 Share Posted October 4, 2021 Thanks Kris,Mine does exactly this too, but usually after being used hard, ie trackday, Curborough etc, and recovers randomly several days later.Did sprint school at Curborough and it wouldn't start for the last run of the day. Got it home and circa 2 hours later wouldn't start. Wouldn't start following day. 3 days later I walked past it in the garage, pressed the red button and it started immediately. Mine is a K series, immobilser gone as it caased other issues but being replaced with something modern and better. Link to comment Share on other sites More sharing options...
