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. We have the fuel pump relay pulled. We were just squirting gas in the intake to see if it would fire. That worked on my Magnum engine, maybe not on a hemi.

Using everything from a 2004 Dodge 1500. Computer, wiring harness, fuel pump and transmission. Was running before we pulled it, should run now.

Car is Red and White now.
