When initially turning the key to ON without starting the car just to prime the fuel pump it will make the initial 42.5psi and then the pressure very slowly drops down to 30-35ish, could this be an injector leak or is it just fuel running back to the tank because the pump turned off?
When I installed the new injectors the o rings looked fine and I used lube to install them to keep the o rings from getting pinched or turned over so I don’t think it’s them unless it’s the actual nozzle itself leaking

As long as it holds 30 or so when it's off, should be fine.
I didn't see where and if anyone said it's not the coolant temp sensor, but that's a good instinct - Coolant temp can make motors flood so badly they won't run, or start. Check it out.
