Help! Jeep WON'T START during hot weather

For some reason, my Jeep will not start when the weather is hot

When I turn the key, it only clicks! I replaced the battery recently but that didn't seem to be the issue as I've even used jumper cables and nothing. Once the weather cools, it does start. It may click once and then start or start right off the back.

I pulled the codes (by turning the key 3 times) and I got codes 201, 300, 301, 302, 303, 306. Any ideas?

I had this issue once too. Fixed it by putting on new + and - Batt cables. Seems like when the heat expands the cables there is not enough voltage to do anything. But when not drawing the volts everything comes on. Try putting on new + and - Batt cables

It never even crossed my mind to do this .. I checked every other fuse, relay and cable, since they looked ok, it didn't occur to me ...... ... You think this is why even if I have jumpers on the battery and try to get a spark by touching them (yes I know not the best idea) I don't get anything??? My friend touched the + and - terminal by accident and we got the little spark (of course) but when I did it with mine it didn't do it.
