My S10 takes a delayed amount of time to start up in the mornings. Once it starts for the first time during the day it runs normal and starts fine, it's just that first start up time that takes some cranking to get it going. Its a 2003 with a 4.3 liter V6. It's not when it's cold really, because I can go 4-5 hours without starting it during the day and it starts find, it's just when it sits over night. What would be the problem?
