On the drivers side of the car bolted under the battery, you have to get under the car and remove the center black plastic piece to reach it, it will be right there with two separate plugs going into it, one with alot of wires, one with a few.
There isn't one, its wired into the ECM.
The ecm module is located behind the passenger side kick panel. I don't know of an ecm relay.
There is no timing set for a 2004 jetta, the timing is automatically set by the ECM.

Bad ECM or ECM relay.
The fuel pump works through the fuel pump relay which in turn works through the ECM relay. This does not answer the question of where these relays are and wich ones they are.
ECM is located on drivers side, below the base of the windshield underneath the plenum. You have to remove plenum panel for access.
It's programmed into the engine ECM. You need to either replace the ECM, or have the existing one reflashed with new parameters.
