    2004 Accord won't start.
    Working on a 2004 Accord LX 2.4L. It has 193,000 on the odometer. Car stalled out several times at idle. Now won't restart. Fuel pump is running. Pressure unsure. Weak spark. Injector pulses. New plugs. Cranks OK. Valvetrain moving. After spraying starting fluid it doesn't even cough or sputter. Hooked up a snap-on scanner and I don't get any data movement during cranking. Any ideas.

    Weak spark (battery fully charged?) would indicate that it's time to replace the ignition coil and perhaps the ignition module due to time and mileage.
    If you stalled, you may have another issue with your fuel and/or air delivery. Clean the throttle body and throttle plate. Make certain that you are getting adequate fuel pressure and volumn. You may need to seek additional help locally with these tests due to special tools that are needed to perform these tests properly.
    Scanning for data during a no-start with aftermarket scan tools often won't lead to anything in particular.
    Get the car running and assess for engine related codes at that time.

    . Remove spark plugs and check each cylinder's compression.

    . Check all under hood and under dash fuses with a test light or multimeter.

    . Check for any codes in memory.

    . Check/replace the Crankshaft Position Sensor.

    @CaptainRich: Car has direct ignition. 4 coils fired by ECM. Even with weak fire it should hit with starting fluid.

    @TxGreaseMonkey: Only code in memory is for v-tech error. Have you had problems with crank sensor before on newer honda's? I suspected the crank sensor but was hoping to see no rpm during crank on scan tool. I'm leaning toward ECM because I see no data change at all during crank.

    Yes. These problems tend to involve the Crankshaft Position Sensor (CKP) or the ECM. Keep your fingers crossed that it's the CKP.
