Asked by j.stiegAnswer

Not off to a good start.
I don't see the distribution box like the one you posted.
I see one small box it has one relay three empty spots for relays.
The jetta is gas if that makes a difference.
it's under th left side of dash
Here's a location picture from a New Beetle... same place as the Jetta.

I have replaced lots of in tank fuel pumps before. but was just wondering if this VRS jetta has a fuel pump in the tank?
Yes, under the passenger rear seat... can be checked via current ramping
to see what the pump current demand looks like.

Tap on the bottom of the gas tank (palm of hand, don't go nuts)
while someone is cranking the engine.
If she starts, pump has a worn spot.

that's easy just lifting up the rear seat wish they were all like that.
Pulled out pump, checked out fine, put every thing back together runs good. Its possible there was a dead spot in the motor or a loose crimp.
When ever there is a problem with something that has a relay involved I always start troubleshooting there first, to see if the problem is upstream or downstream.
Yes, dead spot on contact area for brushes... if you had no power at
the pump, then it would be a relay / power supply issue.
Have a shop check the waveform of the current to determine if there
is a dead spot.
The next time she doesn't start, tap on the bottom of the tank to
jiggle the pump motor to a good contact... might not always work.

Here's a clip of the difference between a bad & good pump:
