Hi my 96 5.0 won't start in very cold weather. Recently it went down to -25F and it wouldcrank but wouldn't fire. Warmed up to 34 and it started instantly. Back down and now won't fire again.

I was told there is a coolant temp sensor that could be the issue, but wondering if anyone has had any similar experiences.

 

Having the same problem. Was it the coolant temp sensor or something else?
