starting problem (again)
Discussion
Catherine,
The first rule of modifying car wiring is :
Make one change and test it (start engine !!)
I dont mean to be smug ... now to resolve you problem you will need to use a wiring diagram to find out if the cables start and end in the correct places and you will also need to check the continueity (the connection works !) of each cable.
Do bear in mind my rule no 1 if you do this again though !
Hope you get it fixed.

It sounds like that in lengthening your wires you've created a bad joint somewhere, probably on the low current side as these are more sensitive to poor earthing etc. You can still get the Factory to send you a wiring diagram if you ask them nicely.Also I'cd check that the coil wires are connected teh right way round as I've noticed on mine that teh wire markings are easily removed once a bit oily etc.

We are very sure that there are not wrong connections: We lengthened them one by one. And after it's failing we checked all wires but everything seems to be ok.
It's possible that the earthing is poor, I believe it's original so I think we have to work on it.
Thank you for the tip for a wiring diagram. I've seen a few on the internet, but they are not so good.
This week I ordered a Wedge handbook. I hoop to get it within e few weeks.

Rule Number one when fault finding anything electrical or mechanical for that matter. If it was working before the chances are it is something you've done. Don't believe in coincidence, the earth may have gone bad in the mean time, unlikely (unless you disconnected it to carryout the work, then it would be a valid path to follow). As laborious as it sounds go over again what you've done.
If that seems too large a job at least look at the symptoms of the current fault and try to relate it to a specific area/function of the re-wire and chase it from there.
Good Luck
OK then treat the symptoms, but bare in mind that it has been rewired.
Silly question was it working properly before?
From your original post you said that it seem to start when the key was turned back, When you say 'seem to start' do you mean 'turn over' as opposed to start?
If so then a possible area to begin would be to look at the ignition switch area as turning the key back should stop it from turning over?

Oops, I wrote it in the wrong topic first...
Well, we have some more problems with the electrics:
The leftwindow fails once in a while and I had a starting problem some time ago (topic: www.pistonheads.com/gassing/topic.asp?t=4682&f=12&h=0).
Yes, when the cars seems to start it turns over a few times and then stops.
Tomorrow we visit a friend of us who knows a bit more about cars. We give all the tips to him.

Difficult to tell at this distance but a first stab if it were mine would be:-
1. Your original problem sounds very much like
a. A sticking solenoid on the starter motor or
b. An overheated motor that needs to cool (and possibly be removed and checked out/renewed).
2. The current problem could be that either
a. The ignition switch (key barrel) is spinning freely inside the steering column and making intermittently?
b. The original starter motor problems have reappeared.
c. More likely the rewiring from the switch to the starter motor solenoid is wrong?
I hope this helps, it is not definitive but any decent car electrician should be able to work out a simple starter motor circuit. I don't wish to sound too pessimistic but once you've got it to turn over properly on the switch I suspect that getting it to fire up and run may be a whole new problem!
Happy fault finding

Problem is solved:
On of the plugs wasn't making any contact: The centre of the wire was broken while the outsite still looked normal. By the way, this was a plug we didn't touch before.
Well done
However I take it you are talking about spark plugs here? What plugs have to do with acar not turning over defeats me though
I'm gonna guess that means between the "HT coil" and the "distributor".
Not sure about the 'not turning over' unless it should be 'not firing'. I guess it could have fired for a short while and then failed due to the broken core in the HT lead, caused by getting hot in the vicinity of the break.

This would be the LT lead lead between coil and distributer. Sounds like the core of the cable had a break in it but the outer (sheath) was ok. As the cable flexed the wire would make or break contact - with contact it would turn the engine over and fire, but the vibration from this broke the connection and engine cuts out.
If you know what to look for and use a multimeter you can find it - I solved a similar problem on my brother-in-law's car many years ago after a local mechanic had fitted a new coil, battery and starter motor.
In this case I would guess that renewing / extending other wiring caused the problem to become worse.
Glad its fixed.
