Having major problems with this Clio in starting the car. Starts great sometimes but sometimes it can take 30 or 40 turn overs till the car fires. We have changed the crank shaft sensor, earth lead from battery, checked wiring loom at bulkhead, fitted new Control Temperature Sensor but still having major problems. Had it linked up to computer diagnostics and its not showing any faults. Have read on this site about a quick fix via the ignition but not sure what the guys on about.

Please can someone help - Urgent
