My son traded his car for a 1991 Honda Civic Dx. It has been broken down in front of a busines for 3 weeks. My roomate said that it was the crank angle sensor, so i bought him a new td-18u distributor and replaced it. The car still has the very same problem. I notice that when he turns over the engine, the top pulley (assuming crank pulley) is not turning. There seems to be alot of after maret work done under the hood and would liek to know what else I can do to get the car running. It has a 1.5liter engine 5 speed.
