Default I hit a wall and need help with Fuel Pressure

Okay i hit a dip in the road a little harder then would i probly should have, the nose dipped but not any damage. The car turned over but no fuel pressure.

So i tow it home and decided to go ahead and upgrade the pump and harness while the tank was out of the car. After i replace it, same thing. The car turns over but no fuel pressure and the pump doesnt even bump.

I have really hit my wall with this and dont even know where to start from here. I checked all the fuses and the harness and it all appears to be fine. If something shorted out the PCM would it still turn over?

I posted this hear because it revoles around getting the fuel pump to kick back so the car will fire. But there is a chance it may be deeper. Anyone experience this before or can give me some ideas..

do you hear the pump cycle for a couple seconds when you turn the key on? Have you checked fuel pressure at the rail? If it's not fuel, it could be spark

edit: just saw that you had checked that ... I'm stumped too

Are you getting power at the pump? Pull the plug out of the harness and test? Have you checked all the fuses inside and outside? Sorry you may have, but sometimes I miss simple things
