I seem to have this problem only on colder nights. Why is that? I have had trouble recently with car not starting on cooler days. it will turn over but not start. have had starter, alternator and battery tested. all came back good. do not want to put in shop because it is my only means of transportation. need quick and inexpensive fix.

it doesnt appear to be fuel pump. can hear a slight hum. have reason to believe it is indeed the ignition module. on warmer days it does crank. it seems as if it has a mind of its own
