I have a 2000 chevrolet blazer s-10, with 140,000 miles. In the winter it has problems starting, only when it is below zero. In the summer time it starts fine.

check the temp sending unit for the computer, it may be bad. Also have the fuel injectors pressure cleaned, old ones won't spray enough gas when really cold
