A fuel pressure gauge would be great but if you don't have this just crack open the bolt before the fuel filter and see if fuel comes out. Then crack open the bolt on the fuel rail and see if fuel comes out. It's messy but it will tell you if you have fuel. With the key in the ACC position and those bolts open a bit you should have a 30+ PSI of fuel spilling out (don't open the bolts too much).
