Reply To: no spark when cold

    I have same issue.
    Cod weather , strong crank, no spark with spark tester .
    New distributor, new ignition coil.
    Gets power to AutoShutDown Relay, gets power to electric fuel pump, fuel pump gauge shows sufficient pressure.
    Car last started in September /October just before cold weather.
    Today, July heat: car fired immediately.

    I considered that PCM had a bad solder joint that lost connection in cold weather.
    Could not find exact replacement yet.

    Any guidance welcome.

    Q: since I can still get power to ASD relay in cold weather, does that eliminate the cam sensor as the culprit?
