    How Do I Read Error Codes on 91 Civic Hatchback
    My car won't start... how do you read the codes? I've found conflicting info. My brother
    Thinks it was 1 pause 1 pause 3, but that dosen't seem right for the problem. The car
    Is turning over but won't start... no spark.

    Help, please... thanks.

    Let me say if you are, in fact, throwing a DTC 3 (MAP Sensor) that your car positively won't start. The MAP Sensor controls spark and fuel. Make sure you are really experiencing a DTC 3 first, because this component is very expensive.

    Answer these 3 basic diagnostic questions for me:

    1. When you turn the ignition switch to ON (not START), does the Check Engine Light (CEL) come on and then go off after 2 seconds?

    2. When the CEL goes out, do you hear (or feel) the main relay "click"?

    3. During the 2 second interval that the CEL is on, do you hear the fuel pump in the gas tank run?

    Those questions are how you begin to properly diagnose a Honda that won't start. Answer those questions in a 1-2-3 format for me tonight and we can go from there.

    Glad to hear that. It almost fired up this morning but the starter is sounding worse. Im
    Leaving it be and having a mechanic look at it hopefully tomorrow. Thanks so much!
