I have a 1993 Honda Civic VX Hatchback (Canada Car) and lately it has been stalling out then it wont start. I wait about 15-20 Min then it will start. I can drive for about a couple of miles then the same thing. I have replaced the main Relay (fuel) and same thing. I checked my Codes and got a 15, 20 and 48. I am leaning towards ignition but not sure where to start. Any help would be appreciated. Thanks.
