I have 92' honda civic. Have been driving this car since last 4 years and just completed 150,000 miles. Today morning, I started the car, it made some cranking noise, but I thought it was due to cold weather. I drove the car for 3-4 miles and when I stopped at signal light, car just cut dead. I tried starting it again, but it won't start. I don't think it battery problem as head-lights and stuff just works fine. I have changed timing belt, tranmission,battery last year. I have also got oil change recently. Have been putting regular gas on it and not more then 600 miles/month. What could be the problem? - loose relay/alternator connection - dead coil in spark-plug? - some timing belt issue? - or soe more grave problem? Its old car and I don't want to sepnd too much into repairing..where do I start from?
