Suggestion

Then I would try get a test wire on to it that I could leave in place so that if it wouldn't start, I could check it easily - with the help of the spare person I would be Insisting drives everywhere with me to turn the ignition on when I'm at the back with the multi meter

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

A couple of times recently my C4S hasn't started, most annoying. First time was outside my lads school, most irritating as the C4S is the only thing that sets me apart from the homogenous Audi/VW/BMW types... Turned the key and nothing, lights on but no startee. Embarrassed I walked back home and called a flat bed, as you do. 45 minutes later I headed back and it started first time so all good. Then last week, just outside Vets4pets it did the same thing, luckily there are a couple of shops to wander around nearby so after 45 minutes in Curry's and TK Max I returned to a most disgruntled cat in a box and a fully functioning 996. First thoughts are, could this be temperature related, maybe the 45 minute cool down is the key clue, perhaps a slightly dodgy earth strap somewhere that breaks contact when hot then is fine when cold again. I'm open to suggestions but the odd thing is I use the car every day and it's only done this twice in as many months... I await bang on diagnoses from demort or Alex imminently. First one with a hit wins a lolly P

POST 2Original post

It's either something earth/starter motor lead/strap related or Immobiliser related if you ask me. Is there any clicking/slow cranking/etc. when you try and turn it over or just nothing?

POST 3Original post

Ignition switch is a common problem on the 996, next time give it a good wiggle around, key in and out, wiggle, wiggle :grin:

POST 4 / ORIGINAL POSTEROriginal post

Alex I knew you would be in there quick! I'm Flattered by the fact that you think it might be an earth strap as I first thought. Anyways, no click, 13 odd volts on the gauge, no funny noises, no crank, nothing. Ignition lights but not turning. I replaced the starter in August (cost me a cracked rib but that's another story). I wonder if that could be a clue. If it is an immmobilser thing I wouldn't know where to start

POST 5 / ORIGINAL POSTEROriginal post

I jiggled, I wiggled, I even got out and rocked the car around. Not sure what the other shoppers thought I was up to. And I just happened to have both keys on me so tried them both to no avail. I must admit, I do get a bit of a rush from not knowing if I will get home or not each time I jump in. It's like playing Russian roulette

POST 6Original post

I would've thought anything starter related would at least make a clicking noise of slow crank now and again...........so I'll give with the immobiliser theory or Kris' Wiggle it just a little bit, I want to see you wiggle it just a little bit, as it grooves :wack:

POST 7 / ORIGINAL POSTEROriginal post

That is a truely cheesy tune, I was much more of a Playing with Knives man myself...

POST 10Original post

Could be a corroded terminal on the starter solenoid- or the solenoid is dodgey and No contact when warm. You need to get at it and check it - just a pain as it is buried behind the alternator. Or just bring it to a qualified person to do it for you. If it was mine, I would try get the wire off and back on, or at least give it a wiggle to make sure it was on properly. Then I would try get a test wire on to it that I could leave in place so that if it wouldn't start, I could check it easily - with the help of the spare person I would be Insisting drives everywhere with me to turn the ignition on when I'm at the back with the multi meter

POST 11Original post

Sounds as tho its crank postion sensor , same symptons i had

POST 12Original post

I was going to suggest this if the engine was turning over, but the OP says he is getting nothing when the key is turned, so I think this is unlikely. I go along with the suggestions already made, plus possible ignition switch or immobiliser?? These sort of issues where it works sometimes and not others get to me!! However it indicates that there is nothing fundemenally wrong, but something that occurs when warm. Hope you get it sorted.

POST 13Original post

Yep cant be the crank sensor as this wont come into play until the engine is at least turning on the starter.

POST 14Original post

Sounds very like trouble I had with my 993, failed to start when warm only, and would restart if left for 30-40 mins, in my case it was, as some above suggested, a stuck starter solenoid which only surfaced when it was hot and resistance increased. 993's are quite susceptible to this fault due to position of the starter motor and the air getting blown at it from the cylinders .. not sure if 996's suffer as much from starter motor problems?

POST 15Original post

If the lights are staying on I would go for starter solenoid or ignition switch. MC
