Ford Focus mk2 fuel pump problem

[#1Batman]

Hi all, I’m new to the forum. Have read a lot of good into on here and thought I’d sign up as I have a problem with my focus 😐. The fuel pump is not working. I have checked all fuses and replaced relays, I have checked the inertia switch and it’s ok, and I have replaced the fuel pump but still no luck. The fuel pump does not kick in at all, can’t hear it making any noise and no fuel coming up the line. The fuel gauge works fine, and I have spliced the main wire and run another wire to it and connected it to another power source when the key is turned on. This is only temporary to diagnose and move the car when I need to, because I’m worried it will do more damage by either not regulating fuel pressure or hurting the electrical system more. With the other power source hooked up the pump works great and car starts and runs beautifully. The engine light is also on. Can anyone shed some light on what it could be before I take it into a shop? Does the mk2 have a fuel pump driver module? Thanks heaps 😁
