Throttle body positioning sensor?
So, lately my jeep has been having a hard time starting. It rolls over, is getting enough fuel, and the battery and whatnot is good. sometimes it will start right up and other times I have to roll it over a few times. Holding the pedal to the floor or pumping the pedal will help once in a while, but not always. I can spray starting fluid into the butterfly and clean off the sensor and it will start for a few days but then I have the same issues. I'm thinking it's the tbps or maybe the crank sensor... Any ideas?
Oh, and when it's hot outside and idling in park or sitting still in drive, it will flood itself and die. It can idle in neutral all day long with no issues. Don't know if it's related or not... Thanks!

I also redid the intake gasket because it was leaking and the exhaust because the manifold was cracked about a month ago. That helped. Thought the problem was fixed, but it started doing it again.

I think it's flooding because you can smell gas really bad. when it sits for a while after it dies, it will start right up. I've checked the fuel rail and the rest of the fuel system. Pressures are fine.

I don't think it's cap and rotor. I've checked it and seems fine. It doesn't seem to fit with the spraying into the intake and it running fine for a couple days...
