944 s2 wont start

[matsleight]

Broken down a few times now and only once needed recovery. Titanic guys pointed me to starter type prob.
So starter has been replaced Northway couldnt find any problems and car worked for 48hrs ok, but tonight my car wont start.
Pretty sure its not immob as light goes out when try turn over (Reading OPC replaced socket 2 weeks ago when first broke down), and reasonable sure can hear clicks from solenoid.
Battery seems fine (13) - can use windows stereo etc.
I get no turn over at all
I did hear clicky/sparky sounds from under fuse box so would this point to lose connection ? I have swapped my dme relay and no help
I really dont know what to do and am at end of tether after spending 2k on it this week allready.
Think can leave it at petrol station overnight and get recovered to Northway in morning but they already said they cant find anything wrong, so I have no idea what to do now.
Any advice appreciated.

Mat,

it might be the battery: often there is enough power to power lights/windows/ radio but not ewnough to turn engine- it needs one helluva' whack to turn over.

One way to check if its the immobiliser or not: can it be push started? If yes, then its not the immobiliser- this would not allow the engine to start under any conditions

If it can, then its not the immobiliser.
Jump starting the car should be OK (can you check beforehand with a multimeter)> But if you are charding the battery do not use thre Boost- this could fry the DME relay!

Just managed to start it an hour or so later, reasonably sure its an electrics thing, but no idea what the difference is between starting now and non starting earlier.... Rennlist have suggested the contacts under fuse box sometimes get knackered, so will contact clean tomorrow. Anyone know if there is a typical break point in the fuse box area? How much auto electricians cost etc?

I have had no titanic posts either guessing mail server down, you see this request there too when it comes back ;-)

Change the earth strap, these can apear to be OK but go high resistance, It maybe worth a try. I once had to dodgy starters on the trot that worked sparodically It took a 3rd one to sort the problem. Good luck.

Is that 13v figure for the battery from the dash gauge when it's under load?

You need to measure the voltage across the battery terminals with a meter when you try to crank it. I had wierd power probs for a while before a proper auto electrician simply tested it this way.

Yep 13 from dash, drops slightly when key is in turnover posistion not as far down as 12 though.
Rennlist have suggested reference sensers and the ground straps on bell housing to body or maybe ignition barrel itself.
I 'll try contact cleaning these too. I hate intermittant problems, started first time this morning.
Cheers for advice so far, any other thoughts are appreciated.
