There should be fuel pressure in the fuel distributor at all times as well as the fuel injector lines. Make sure that when you turn on the ignition you hear the fuel pump turn on for a second and then turn off. You can also disconnect the fuel like coming from the fuel pump to the FD and turn on the ignition, make sure the line is secured in a bucket or some sort of container to catch gas, to see if any comes out. If you hear the fuel pump turn on, but nothing comes out, check for pinched fuel lines.
Once you have fuel at the FD, let us know and we will go from there.
