OK, need some help from the brain trust. Out driving this morning, temperature about 6 celcius, no rain. At low speed, I think low revs in second gear, taking a mild right turn, the engine cut out. Completely shut itself off as if I had turned the key.

I thought, "hmmm, thats new". I tried to start it again, but nothing, turned the key, no lights, no power, dead silence. Tried a few more times, nothing. Popped the hood, looked around, nothing out of the ordinary. Got back in the car, tried again, nothing. Sat for a few minutes and thought about it, tried starting again, and everything acts normal, car starts and runs fine, made it to my destination a few minutes away.

Any idea what this could be? The whole key/ignition assembly is original to the car, could it be on its way out?

It's worth swapping the ignition switch out. . .they are pretty cheap, and my old NA definately had cutting out problems like you are describing.

Yeah, just checked the price, $12.95 US. Not bad at all, checked Clarks Garage and they have a nice writeup with pictures on doing it for a 924S which uses the same part and has the same interior. Seems fairly straight forward.

Bad news there - Clark's writeup doesn't apply to your 80. I have done Red and Shaggy, and Red was much easier to disassemble. As an added bonus, Shaggy's turn signal innards had become quite brittle, and the whole assembly fell irreparably into bits once the mounting screws were no longer holding it all together.

On the plus side of that, the replacement was available at the Parts Bin or Autohaus and was pretty cheap.

So, my tips: have new turn signal stalk on hand, and unplug the stalk wiring from under the dash (after dropping ECU) before you start tugging on the stalks.

Ignition switch is my guess, too. Easy job, but like Rasta says, have new turn signal and wiper switches on hand. And this is probably a given for you, Chrenan, but don't forget to disconnect the battery.

Hey, its always good to remember the basics, I'll disconnect the battery! Ordered the parts, going to swap out the lock assembly while I am in there too, it is tought to get my key in and out sometimes, lots of slop.

When you say 'lock assembly' do you mean the carrier as well? I had one of those out and couldn't for the life of me figure out (without knowing how and where to drill) how to get the ignition tumbler out. I finally decided I wasn't supposed to know and ended up swapping in another carrier with the tumbler in it (and the new switch!). Have fun!

Hmmm, hopefully it isn't too difficult, this is what I was planning to swap in:

There's a retainer you have to push in with a small punch or pick.

Gotcha, once I've got it in hand I'll ask some questions if I can't figure it out.

Weird thing is, I went out tonight drove to a destination no problem, also no problem on the way back. Before it cut out this morning I was on a particularly bumpy section of road, maybe it shook the switch the wrong way. Seems to be an intermitent problem at the moment, but I'll still do the work for peace of mind.

The switch carrier in my world was from the 931 - same as the 944. Tumblers are fairly straightforward to change, which was why the 931 one stumped me. I'll bet the 924 setup is different. Rasta'a right - often you make sure the key's in, depress a tang with a pick or small screwdriver and pull out the lock cylinder. I'm really interested to see how yours works.

When my ignition switch went south the car would run fine and then for no apparent reason just die. Stone cold dead. No wiggling of wires or twisting of keys would make a difference. Then, all of a sudden! it would decide to run again.

Just checked Haynes. 924 looks same as 944. Okay, Rasta, how does the tumbler come out?

Chrenan - yours should already have a hole to insert a pick to release it. Should find it on the steering shaft side of the lock holder within a groove and about 1/4"-1/2" of the end of the holder.
Slam - you'd have to drill a hole as shown here -
