Question

changed plugs and wires got fuel system had a fuel system cleaning for injectors and throttle body changed crank sensor could it b my fuel pump

Answer 1

Hi there,

P0305 indicates a misfire on cylinder #5. This isn't the result of something like the fuel pump that would affect the whole engine. I would check for intake manifold gasket leaks and a possible issue with the fuel injector. It's also possible there is a problem with the engine internally on cylinder 5. Take a compression test.
