2004 Jeep Grand Cherokee V8 won't start

I'm wondering if all of these items are related electrically because my 2004 Jeep Grand Cherokee V8
1) won't start, Gage says empty tank is full.
2) AC clutch isn't turning so AC doesn't work.
3) Windows won't go down even after checking all wires in door jams they're good, and replacing master control on driver door.

I've checked all fuses they're fine, I even replaced the relays. Windows stop working so I went through the process of all the checks. wanting to use the air conditioner because windows wouldn't go down, that's when I noticed the AC didn't work.
Two weeks later while still trying to fix the other 2 problems now it won't start, gas gauge indicating empty even though the tanker's full.

Anyone know if they are related electrically? Or what to do?

1) check fuel pressure with a gauge, post PSI. Check codes, maybe a P046x code, or bus issue.
2) Check AC pressures, again ck codes.
3) Windows - do you have a wiring diagram?

When I see the price of OEM I think aftermarket.

you should check codes. Post all the codes you get.

Here is front wiring it should be a easy check.
