Hemi won't fire

We sent the ECM to Solo Electronics and had the security system deleted. Where does it read fuel pressure? I haven't seen a sensor for that. There is no fuel pressure sensor on the wiring diagram. Maybe I missed that one. That may be the problem. We haven't put fuel in the tank yet.

There is no fuel pressure sensor .Ford uses a pressure sensor to pulse width the fuel pump for pressure control , but the factory mopar system uses a fuel pump module that regulates fuel pressure to a single line . Most guys use a corvette style fuel filter with a return to regulate pressure.
If you want to check pressure there is no Schrader valve , you have to T in a fuel gauge.
It would be best to get the fuel from the injectors, the fuel may just puddle into the intake.
If the engine has set for a while , the injectors usually will stick closed . The modern fuels are hard on things.
