Ok I have reviewed what you have discussed so far with the prior expert, we are going to start from the beginning so we can get to the bottom of your problem.
To start the brown wires you have been asking about are ground wires for serveral different circuits throughout the vehicle, the connector they are all plugged into is called a bridge connector, and all this means it is a common ground point and it serves as a point to hook up several ground wires instead of having many different ground mounting points.
Ok great I want you to check the wire that goes to the starter solenoid for battery voltage when the key is in the start position.
If you have the proper battery voltage then the starter is no good and will need replacement.
If you don't have the proper battery voltage then the vehicle will need to be hooked up to diagnostic equipment, because it can be related to the EWS system and because there are several components in that system that can cause this, it will need to be tested while hooked up to diagnostics.
The solenoid is item # 1 in the photo you will have a large red battery cable going to it, and a small wire that is connected to one of the terminals, this small wire is the wire you want to take the voltage measurement at, you want to have at least 12volts on this wire.

It is located on the drivers side of the engine underneath the intake manifold, it is a very tight area to get into so be patient so no further damage is done to any of the surrounding components, because there are several plastic components that can break if your not careful.
Here is a picture of the starter location from the top of the vehicle with the intake manifold removed. It is all the way at the rear portion with the 2 cables going to it with the RED cable ends.
