In relation to your query there are a couple of other elements of your account that I would recommend you check to make sure that are no problems stopping your ads from running.
Firstly, I would recommend you check whether your ads are approved or disapproved. You can check this on the "Ads" tab of your campaign.
Secondly, I would check the "Keywords" tab in your account to make sure that there are no problems with your keywords. There may well be Quality Score issues that are affecting your ad serving.
Thirdly, I would also try checking out the Ad Preview Tool. This can give you some extra information on whether your ads are running or not and why.
I hope this helps!
