When you say it won't turn-over, that means it won't crank? Does it crank, when you hit the starter?

You really need somebody to crank the engine while you do the testing.

The B+ to the injectors should go hot when you turn the key on. You can unplug the connector from one of the injectors, turn the key on, check for voltage at one of the terminals with a 12 volt test-lite. If there is no voltage, you may have a blown fuse, somewhere.

Yes, if you use a noid lite plugged into the injector plug and crank the engine, the noid lite should flash, meaning, there is B+ and ground at the injector plug.

You should have done your testing before you bought any parts. You can't hardly do any testing without a helper to crank the engine. I don't know how you tested for spark at the plugs without a helper? I guess you could lay the spark tester where you could visibly see it, while you cranked the engine. Are you sure you have spark with the engine cranking?

I reread some of your posts, so the pump won't run? My hearing is no good, I can't sit in the vehicle and hear the pump run. Before the vehicle quit, could you turn the key on and hear the pump prime from inside the vehicle? Just by turning the key on, not cranking, the pump should run for a few seconds.

There should be a fuel pump prime connector, You should be able to trace it from the relay. I believe it is a red wire. You can run B+ to that connector, the pump should run. After you hook it up, you can listen at the rear of the vehicle. Don't have to use the key or anything. If you run B+ to that connector, you have to be sure what your doing, I can't see it from here. If you try that test don't forget to unhook the wire.
