I found with my car, that to get the fuel to the rail is as simple as hitting the check valve on the rail.. the schrader valve. If it hisses out a bunch of air, that was the problem, if fuel comes out just a dripple, you kicked your fuel pump, if she squirts hard then you're good.
Also if the computer knows that it isn't getting spark [crank sensor, cam sensor, icm bad], then it won't rattle the injectors. So if you have no spark, but the injectors are firing, it'* a coil/wire/plug problem.
The computer isn't going to know there isn't fuel pressure so it won't spark, so the no spark is not related to the running out of gas.
