not getting gas through injectors

[squatch]

I Have a 1990 Bronco II that I bought that has not run in about 3 years . I replaced the fuel pump, fuel pressure regulator, and computer. I am getting gas to the fuel rail at about 40-45psi . doesn't hold pressure and is not going through the injectors. All relays are working. Is it posable all the injectors are clogged or am I missing something else

have you used a noid light to check that your getting voltage/ signal to the injectors?
