2005 Jeep 5.7 Hemi problems

I have a 2005 Jeep with a hemi, but it starts and runs for like 3 seconds and stops. Does anyone have a clue what it could be?
We have fuel, got a new pump. There is o2 sensors missing. Catalysts is gone. Got all new fuses and relays but not every slot is filled, only those what's on the top of the cover

Is it holding fuel pressure? I had a hole in a hose inside the tank once that gave similar issues

It holds fuel pressure, what I figured out now is when I give a little throttle it dies.
Thought it could be injectors?

Thats good. Possibly injectors or maybe a vacuum leak. Its getting too much or too little air or fuel and im assuming the ecu is freaking out. Ik that doesn't exactly narrow it down

Is there a way to check injectors easily?
I'm gonna clean the throttle body now

Depends how easy they are to take off. Probably remove fuel rail and theyll Probably just pop out. I'd watch a video. But once they're out you can hook up a 12v battery and make them squirt. Look for injectors cleaning videos. You kinda hook up cleaner and a hose to the injectors and make them spray

I know it's a late reply, but we found the error. We thought it was fuel pressure but somewhere along the fuel lines the pipe is blocked or bent. So we just replaced it. It's running smooth now!

Not sure if newer cars are different, on my old project to test the injectors you check the resistance across the injectors cold and hot and all injectors need to be within 0.1 ohm of each other.
