Having issues with my 2016 Civic EX not starting. All I get is a clicking sound. Thought it was the battery so we swapped that, and still having the same issue. Was suggested to change the starter relay, but can’t find where they are located, just that there are two of them. From everything I’ve seen they are not in the under the hood fuse/relay box. Does anyone know where they are?

Well this is an issue. I called the Honda dealership and they don’t even have that part listed. So if it is bad how is it supposed to be replaced?

i would test the relays before trying to replace the part.

theres a link on these forums somewhre to download a firefox browser that opens up the honda techinfo page and you can view the wiring diagrams.

then locate the pins of the relays, and put 12v on one pin and ground on the other, and you should hear it click, which means its working.

Ever fix your issue? I am going down a rabbit hole and this may be a potential issue/solution.

Curious to hear how you resolved yours.

Check towards the rear if you have oil leaking from the valve cover gasket, I've seen it with oil leaking on the starter
Thanks for this info, funny enough I did notice the area was wet on top around the valve cover. I would assume its also wet in the rear then.. I am about to get out here in the next 30min and take a look underneath remove the body cover and look at the connections on the starter.

Referring back to the relay box in the above post, the entire unit is one assembly so you can't even just take 1 relay and swap with the starter one as the thing is all housed within that plastic rectangle that buddy circled..

My daughter had a similar problem on her LX 2017, it wouldn't start, good battery, the starter was replaced, it was ok for a few days but the problem came back, the valve gasket cover was leaking onto the starter. The repair was done on warranty.
Have a look in this thread, same problem, look at the pictures of the starter:

Wow this thing is hidden in there.. I don’t even understand how one removes this thing without removing half the front end shit.. like who came up with this.
The unit does have oil on the body of it.. I can’t even access the plugs to clean things off..

depending of your milage, the seals and gaskets are warranted until 100k kilometres or 5years. You could also claim the price of the starter
I’m in Canada if that matters.

here it is. went through the side. Is she bad?
