Hi everyone, i'm new to this site and i'm having problems with my prelude. A few weeks ago i went to work and as i was getting off my exit from the interstate and turning on a green light my car just all of sudden shuts down on me. I've replaced the the main relay, distributor, ignition coil, spark plugs wire, and spark plugs. Getting fuel and spark but spark is colored yellow, not blue and white. NEED HELP??????

 

Have you tested the battery and/or alternator?

 

haven't check the alternator yet, pretty sure my battery is still good

 

Double check all of my fuses, every one of them are good. What could be the cause of a weak spark.
