S-10 Problems

[275 pro]

Need some help with my old S-10 again. Now when it is cold and first thing in the mornings, it is almost impossible to crank. You have to pump the gas pedal numerous times and when it does finally crank you have to continue this. Now, after it warms up OR in the afternoon when it is hot outside, it cranks fine and runs and idles fine. Any ideas what could cause this? Could this be the fuel pump? Any help is appreciated.
