95 5.8 351w, replaced the fuel pump, now I'm getting a crank no fire. When I turn the key on you can hear the fuel pump kick on, I checked and I have fuel pressure. I also checked to make sure I'm getting good spark, which I am. Could this be an injector problem?

 

It could be, but why did you replace the fuel pump in the first place? and are you sure you're getting spark at every cylinder? (that usually would lead to a barely-running condition, but have enough cylinders failing and it won't start).
