Plugs leads or coils breaking down when warm. Or it could be tight valves when the motor warms everything expands abe if there is not enough clearance in the valves they don't close fully and allow combustion pressure to leak out. To test this do a compression test when hot and cold and compare.

because the combustion inside the engine is going wrong the quantity of air getting inside is not the needed quantity maybe less than or more in cold will cause such problem once the engine warm up than the engine temperature is up you will not find this problem because the point of firing will be near

Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

When the weather is very cold (below zero) the car will not even try to turn over it wil only click at the starter and ignition no turn battery is fine never does this any other time. only cold, but once...


It is normal for batteries to lose a good deal of their power due to cold temperatures. If you want better starting power, try using a battery charger/maintainer overnight. It should charge at no more than 2 amps. The slow trickle charging overnight will charge and warm up the battery and allow it to develop full power for a cold morning start.

Will not start when engine warm


Sounds more like your ignition module is getting hot and not working. I'd go there first before replacing the ECM. You can remove the ignition module and most NAPA stores have the ability to test them for you. Make sure they test it at least 5 times. This way it'll simulate starting and stopping.
