Sorry to ask so many questions, but to get an idea of the problem I need to ask. If you were having a problem starting the vehicle when it is hot outside that would be easy. How many miles do you have and how long has this been happening?
Customer: replied 8 years ago.
it just started doing it & it has 200,000 miles
Expert:  Tech413 replied 8 years ago.
Does it make a difference what the fuel level is? Does it do it more often when the tank has more or less fuel or have you noticed?
Customer: replied 8 years ago.
either it just does it when it's below 32 degrees
Expert:  Tech413 replied 8 years ago.
My initial thought would be the fuel pump is freezing up. If this is the original pump then all the weather seals have probably deteriorated. allowing moisture into the electric motor. This would make the most sense given the ambient temperature.
Customer: replied 8 years ago.

do i have to put a whole new pump in or just change the seals

Expert:  Tech413 replied 8 years ago.
The pump comes as one assembly pump, fuel level sensor. The only problem you may run into is that when you install a new pump the computer may need to be reprogrammed to be calibrated to the new fuel level sensor. You will know this if the low fuel light starts flashing after you install the new pump assembly.
