The fuel pump is likely not providing enough pressure to the injectors or the injectors are clogged.
1. Verify the fuel pump is putting out sufficient volume and pressure
2. Verify the injectors are spraying.
The path between the fuel pump and the fuel rail is only about 12 inches so not much to go wrong there.
I would start with the fuel pump. If it isn’t up to snuff, it doesn’t matter whether the injectors are clogged or working.
The fuel pump isn’t that hard to get to. In fact, I think it’s easier to get to than the injectors.
