Before parting with the hard earned cash at the garage, not that I am trying to deprive Mr Faulks of a sale you need to check the wiring. The lead coming from the ignition to the coil breaks down.
You need to check the supply to this when the ign is switched on, if no power then run a wire from the positive terminal on the back of the bulkhead up to the positive terminal of the coil and check for a spark when you turn it over. Dont leave this conected as after an hour it will melt the coil, so only a temporary fix to get it running. This is a very common fault on the Atmo.
Also check the conection sending the signal from the dizzy to the ignition module, mine recently stopped no spark what so ever. Wriggled the connection frimly and this appeared to fix the problem and the car ran fine afterwards. Although I am not 100% sure this was the cause TBH.
Apparently according to the manual you can damage the ignition module if you run the engine with one or more of the spark plug leads removed, Ive done it loads of times without realising the possible risk but it's still fine.
Check the wiring supplies and signals sent first, it is unlikeley to be the coil as they tend to break down over a period of time giving warnings by producing a missfire.
The signal from the dizzy can be checked using a strong magnet passed passed the rotor head or you can carefully use a rough metal file and fly lead to generate pulses to make the coil spark.
Just some pointers if you wish to do some checks yourself and save money at the garage. Hope I'm not trying to teach you to suck eggs.
