How are you all doing? So I've been having this issue now for the past couple of weeks and i have replaced my battery first, then i changed out my alternator and put a new alternator in my jeep also. Im driving an 06 grand cherokee 5.7l hemi as stated in the title. So the issue is that I can start my car drive it around for the day but if it sits for a long period of time like it does through out the night, in the morning it wont start even after replacing both battery with a optima, and alternator. Right now im pretty clueless what to look at night, When it doesn't start the starter does make a click so it is engaging and seems to be working it just always needs a jump. I'm trying to stay away from the expensive car care center on post so if anyone has any suggestions on what to look at next im all ears!

On the starter is a yellow (signal) wire make sure it is not corroded and the connection is good and tight. Could be that the starter is going bad as well, this is fairly common.

Drivers side under the exhaust manifold toward rear of the motor it's a pain to get to there are a couple of write ups here on the forum. Jumping it is probably giving it enough Umph to get past the dead spot and spin, someone mentioned a parasitic draw that is possible as well. Leave the Jeep overnight remove the battery to have it tested if it's good then you will know.

If a jump gets it fired up right away, I'd suspect a parasitic drain on the battery.

They can be hard to find, but all you really need is time and a multimeter capable of displaying a load drawn in amps. If you don't have this, best to just find someone who does.
