No Fuel Pressure

I have no fuel pressure. I replaced the fuel pump, crank position sensor, and performed an ohm reading on the relay in the main fuse box in the engine compartment, I even checked the electronic ignition module. I was told that if the ignition module wasn't working that the fuel pump wouldn't respond. I've lost all hope of getting my truck running again without spending a fortune to have someone else mess a bunch of other things up in the process of figuring out my issue. Please help!!!!!! This is my only set of wheels...

 

U sure u have no fuel pressure? Have u hooked up a gauge to the fuel system? Check out ur fuel pressure regulator. Does the engine just crank over and not start?
