Need help****** GLS550 Starter replacement

When I try to start the car and push the button it won’t start, but I do hear a loud click. I changed the battery and confirmed the starter relay is good. Could it be anything other than the starter? I went ahead and bought a new starter, but when under the car it looks like it’s going to be a nightmare to get to. Anyone change one and have some tips and tricks?

Did you verify the battery is indeed fully charged and throw it on a charger? A lot of new batteries may have been sitting on a shelf and you'd be surprised how many batteries sold are not ready to use.

I tried starting it once I installed it and the same click. I charged the battery for two days, and the same thing.

Can you provide a little more info on the background here? For instance, when was the last time the vehicle started successfully, after what period of time did the no start issue occur, how old was the previous battery, etc. The more info of this nature can determine what could be occuring.
It's really rare a starter fails, it is usually an electrical or a fuel delivery situation.
Also, do you have access to a scanner or something like a DAS that can pull some info? That would be helpful to determine what's up.

Are you hearing a single click or a repetitive clicking for as long as you keep the start button pressed?

I realized I didn't answer your question - and I can't attach a PDF for some reason so I'll try and PM you the procedure.
