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?
