The last week we have been having cold weather (below zero temps). My truck won't start. It sounds like it is firing but i just won't take off. I tried jumping my battery, no help. I tried changing out my battery, no help there too. I placed heat lamps in my engine compartment and tried placing heat lamps on my fuel line. Still no help. It still sounds like it is going to fire up but then it stops all i hear is my starter. This is really frustrating me. What is the next thing i do? Should I try changing my spark plugs? Any help would be great now.

 

Try a new coil.
