Just picked my 2021 superstock up from Koons 3 weeks ago. I trailered the car home and have not drove or started the car since. Today I drove 11 miles to my detail shop to have the car ppf and ceramic coated. Car drove perfect to his shop once I got there I shut the car off and when I went to start the car to pull it inside it just cranked and cranked and cranked and will not start. The fuel pumps turn on the starter is obviously working but the car will not start. My car now has 31 miles on it and will not run. I have seen a fuel pressure module on the fuel rail on some earlier cars cause a similar issue but has anyone on a new redeye had this issue lately and any knows fixes?

1st line is indicative of the problem no doubt.
OP, check batt voltage, if its too low, which happens a lot with these vehicles, can result in a no-start, even though some systems & functions will work.
I will definitely look into that and test the battery. It’s odd it almost seems like the car is not getting fuel it cranks hard the battery voltage on performance pages says 14.2. Who knows I will def check the battery thanks for the suggestion.

I would definitely check your battery. The batteries in these cars discharge over time just sitting there. Driving short distances does not recharge the battery. Make sure that your battery is 100% as it can crank but not start with low battery voltage.

That happened to my Hellcat previously and it was a bad fuel pump relay in the trunk fuse box. Probably not the same issue with yours but I’ll be curious as to what you find out.
I also planning on picking up a Redeye from Koons soon. Ordered last November 😁

Does the SRT page show fuel pressure at the rails? If the car is cranking hard probably not tje battery.
No fuel pressure gauge that I am aware of. You get boost pressure, oil pressure and tire pressure.

good point about the battery haha. I’m surprised it’s reading 14 volts during crank. That does point to fuel

I’d put a manual fuel pressure guage in the rail then and see if you have pressure there. That’s the next thing to check after battery. Should have a schrader valve on the rail for that.
