no fuel getting to injectors

hi people just joined and was wondering if anyone can tell me what problem i might have as i have fuel all the way to the injector unit but nothing coming out to the injectors on my mrk  golf gli and it will not start thank you fellows of the relm

Too low fuel pressure, probably caused by a weak battery or dodgy wires, meaning that less than 12V is delivered to the fuel pump when you try to start it. Can you bump start the car successfully?

Might be worth a squirt of this?
