Poor Starter

[Guest]

A 1984 A plate 924, cosmetically good and went through the mot (the first since I bought her) without a single problem.

When I start her up, she is a little jumpy, and it almost sounds like she's firing on just 3 cylinders. A few revs, and typically the problem goes away, and once it's gone, then she runs really well.

If I stop for a couple of hours or less, then trying to restart is a real problem. I have been trying for as much as 5 minutes (very embarrassing) and when she eventually starts, then the same 3 cylinder feeling before once it's ticking over properly, the problem is gone again.

Is this a common fault?

Is there a part or parts I should look to fit?

Or does she need some specialist treatment?

All help or advice much appreciated.

Hi Andy.

I have a 1984 924. When I first got it I had the same problems. Changed the sunroof seal which stopped the leak. New Rear Hatch seal did not. After a lot of head scratching I ended up cutting some of the new seal away to let water flow away and not overflow into the boot.
The hot start was a problem from new. If the car is to be started from warm, even if temp gauge shows cold use full throttle. Also check the 5th injector is working. The injector is set into the inlet manifold. It should pump when the engine is turning. This is fired by a sensor at the back of the engine. I am told it is impossible to get to without removing the head. Once the engine is running the 5th injector stops.
You will find that most things under the bonnet get baked.
If the headlights start playing up, not dipping properly, very dim drive lights staying on check the earth leads from the pods to the earth bolts on the chassis. Mine looked ok but had broken inside.
Afew other things have gone wrong, but in 3 years of daily use I have always managed to get where I wanted and loved every mile behind the wheel.

O.K. Firstly Terry is right in that the 5th injector is controlled by the 'sensor at the back of the engine' which is called the thermo-time switch and it earths the cold start injector if the coolant is cold. It is not impossible to get to it but it is blasted awkward. If you want to check it out, drain and collect the coolant, and at the back of the head disconnect the two coolant hoses from the stubs in the picture, and then unbolt the casting, ease it out and disconnect the wires.
