08 RDX won’t start
Hello!
I have replaced the battery, alternator & tensioner pulley and my battery is still draining and won’t start. All fuses look ok at first glance. No leaks. Could it be the starter?

Unlikely to be the starter. You'll need to pull fuses and observe for the current to stop flowing to DIY the cause, but there are some modules which are known to stay awake (including as I recall the AC relay, the Hands Free Link and the audio amp) and cause a drain.

Ok, so we pulled all the fuses and I didn’t observe any results. Will likely try this method again just to be 100% sure. I am by no means a car expert, or even somewhat knowledgeable. How would one go about testing the AC relay, hands free etc. will those also be connected to a fuse?

If it was me I'd use a multimeter to measure the current drain with the car off and then pull the fuses related to the indicated systems to see if the car-off current drain was reduced.
The clutch relay (underhood fuse box) is in position 12 and it looks like fuse 23 is audio and handsfree link
Also check fuse 14 on the inside fuse block as well as 31 and 35.
14: Various audio stuff
31: Stereo amp and subwoofer
35: Acura link and HFL
I tried to post pics out of the FSM but that didn't go so well, sorry!
