My most recent S15 is really struggling to start when cold, and when it does fire, it sounds like an Impreza until it is warm. It has an unmapped powerfc so I fitted a stock ECU to see if it was that. Still the same.
If it fires and you don't catch it, it'll die and not start again and reek of petrol.
I've a feeling it may be the ECU temp sensor because it runs well once it's warm. Any ideas?
