Help! HC Challenger Won't Start

I had a chiller kit installed on my HC with a 1.5 gallon aluminum expansion tank.

Last night, I went outside to see what the chiller kit could do. Keep in mind, I also switched to E85 setup when chiller kit was installed. Car has a tune that allows it to start, but that's about it. Headed to get it tuned on 7/5.

Last night, no issues starting. Had to crank about 3 seconds due to E85, but started fine. I needed to insulate the expansion tank, so I vacuumed out all of the fluid, and removed it. Nothing odd there. 2 bolts and 2 coolant lines. I insulated the tank, reinstalled with no issues. Refilled the tank, no spillage.

I wanted to see if I could see where my coolant fans are kicking on at, so I plugged in the OBD cable to load up HP tuners. I then tried to start the car, fuel pumps kick on, dash lights up, but when I press the ingition button, it does not turn over.

I've not had any issues with the battery. I unhooked the battery for a couple of minutes and reconnected the terminal. No change.

I tried to load up HP Tuners scan tool, but it's not wanting to connect.

Any suggestions?

Thank You in advance.

My WAG is the battery is low, discharged. Probably from lack of use and not being on a charger/maintainer while the car was being mod'd. The slow crank was not because of E85 but because of low battery.

My 2018 Hellcat would slow crank a bit when I let it sit too long unused and this with 91 (E10).
