1999 Malibu starting issues

I have a 1999 Malibu that i have been having problems getting to start during cool weather doestnt have to be cold even in the 60's. seems like it is taking moisture somewhere. During the middle of the day it starts fine. Have spark and am getting gas. Went out tonight car wouldnt start got under the hood and started messing around unhooked two plug wires from one of the coils went back turned the key and it started up. shut it off hooked back up coil and started fine again. waited for a little while went back out tried to start with coil hooked up and again would not fire. unhooked the coil again and got it to start. Any ideas on what might be going on. Please any help would be great.

thanks

little more information car did sit for about one year without being used prior to us getting and trying to get it back in running order.
