At first I thought this might be a battery problem in the weather I'm in but here it goes. Just this past week my yeep has been giving me problems when I start her up. The first day it happened I was on my way home from work and it was about 35*c, so i got home and didn't touch my car for the car till the next morning. Started up the jeep perfectly, at 22*c, worked 5h, 33*c, rough start again, this continues for 3 days. So could it be the battery messing with me?

 

I assume you were explaining the rough start mentioned at the end, for the whole thing? Run to a place like autozone and have them load test your battery, it is free.

 

more info. slow cranking? excesive cranking? rough idle after start? what engine?

 

Yes, "rough start" does not describe the problem in detail. Does it turn over well but not start? Does it not turn over well?

1. Freshen all battery connections. Remove cables, clean till shiny and the posts, reconnect. Load test battery, which any parts store will do for free for you.

2. Review tuneup status. Plugs, wires, cap, rotor. Secondary ignition needs to be strong for the engine to fire quickly.

 

Sorry, excessive start, caused all week at warmer temps

 

By excessive start, do you mean "extended crank times"? Description is still a little confusing.

Irregardless, you need to remove your battery cables and clean them and the battery posts until shiny. As long as you have the cables off, take the battery to a parts store and have them "load test" it. Load testing is the only accurate way of determining battery condition.
