Have you checked the fuselinks? They are located right by the starter solenoid on the positive side, they have little tabs on then showing the gauge.

How do check the voltage on the injectors to make sure they are working like they should

Cedric you might try starting a new thread, you will get more reply's. Use a noid light, plug it in an injector plug and crank the engine, it should flash. There are also fuses in the fuse box that are labeled inj, those will read battery power with the key on. If you don't have a noid light you can if your careful use a test light, put the clamp end on the negative battery terminal and turn on the key and check for power on the red wire at the injector plug, next put the clamp on the clamp on the positive battery terminal and have some crank the engine while you test the black wire for a pulsing light, do this quickly so you don't overload the injector driver in the ECM, if you do overload the driver it means a computer replacement. If all that checks good then you will need to run a ohms test on every injector to find out if they are within specs.

You may have 2 problems. If it's not starting it may be the fuel shut off switch Check Look to see if the Button needs to be reset.(push down) It's on the fire wall left of the streeting Coulumn. It wont start untill it's push down. Colision can trip it.
