Problem starting truck?

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?

By delay, do you mean it is slow turning over? Lots of batteries hit the crapper with the change in weather. I would be proactive in getting it tested before you are stranded somewhere, it will only get worse with cold.

Well it starts with plenty of battery power when cranking it seems and I feel it has something to do with gas. It starts a little shaky for the first few seconds, then runs fine for the rest of the day.

This has been going on since about June so it's not the change in weather and it hasn't gotten any worse it's the same as when it began doing it. It's taken me to long to get to it but I just haven't had time.

Could it be the coolant temp sensor?

Yes it cranks fine, and starts right away ever time except for the first start of the day.

I haven't checked the PH of my antifreeze no

Does anyone know where the coolant temp sensor is on this truck? It's not around the thermostat housing from what I can see.

I don't know darkhorn at the moment I have the coolant temp sensor and want to replace it, I'll check the PH when I have available supplies to do so. And what do you do if the PH is too high?
