Wont start when weather is cold.

i just did some more work on the problem, and it looks like a new coil fixed what was wrong with mine. here is the reasoning that lead to the possible solution. when it is cold outside (below 32F) my truck turns over but will not fire. originally i was told that it was probably a bad temp sensor causing the injection system to flood the vehicle. i changed that and it did not help. i pulled the number 3 plug and grounded it to something to see if i was getting a spark. the truck fired right up. i put the plug back in thinking the problem must have just went away, and the truck would not start again. this lead me to believe that with all the plugs in, there was too much amp draw from the starter in the cold to fire the coils. upon further testing i noticed that i would get a spark just after i let off the key while trying to start with the plug grounded again. i put a new starter and new battery on and that helped somewhat. today i took the coil packs off and ohmed them out. they were barely getting into the good range at about 75F. i put them in the freezer and ohmed them again. the resistance on the secondary dropped to mere points above the lower limit of the good range. i replaced one of the coil packs because the parts store did not have two in stock. my truck seems to start fine now. tomorrow will be the real test though because the temps are forcast to really drop tonight. i'll post back and let you know if it was a solid solution or if it needs more work. i just did some more work on the problem, and it looks like a new coil fixed what was wrong with mine. here is the reasoning that lead to the possible solution. when it is cold outside (below 32F) my truck turns over but will not fire. originally i was told that it was probably a bad temp sensor causing the injection system to flood the vehicle. i changed that and it did not help. i pulled the number 3 plug and grounded it to something to see if i was getting a spark. the truck fired right up. i put the plug back in thinking the problem must have just went away, and the truck would not start again. this lead me to believe that with all the plugs in, there was too much amp draw from the starter in the cold to fire the coils. upon further testing i noticed that i would get a spark just after i let off the key while trying to start with the plug grounded again. i put a new starter and new battery on and that helped somewhat. today i took the coil packs off and ohmed them out. they were barely getting into the good range at about 75F. i put them in the freezer and ohmed them again. the resistance on the secondary dropped to mere points above the lower limit of the good range. i replaced one of the coil packs because the parts store did not have two in stock. my truck seems to start fine now. tomorrow will be the real test though because the temps are forcast to really drop tonight. i'll post back and let you know if it was a solid solution or if it needs more work.
