Your question seems rather confusing. Can you rephrase it?

Are you able to crank the engine?

What are the actual conditions now?

You would need a fuel pressure ghague to attach to the fuel pressure line, either at the fue rail or along the fuel lines.

Some parts stores loan these out.

It ended up to be the fuel pump but now I hear a funny nosie as I rev it how do you tell if its an injector and if you replace one should you do them all?

Injectors don't produce abnormally loud noises. Most tapping noises are from valve lifters.

There is no way to tell if it is going. If an injector fails, you would have misfiring issues.
