Hi all, my st170 wouldn't start properly this morning. Started up ok then after about 10-20 secs cut out. Did this a couple of times and know won't start at all.
There is fuel in it, the electrics all work so it's not the battery. And can't be the starter motor as it did start up and can be heard trying to start the car.

I've noticed the spark plugs are in very poor condition and the ignition leads could benefit from being replaced so have ordere a new set of all which should arrive and get fitted tomorrow. I hope this is all it is, does this problem sound like it's just spark plug/ignition related?
