How to make Measuring of Views of Product Details work in Enhanced Ecommerce?

Question

Google Analytics

Good afternoon, dear colleagues!
Setting up Enhanced Ecommerce through Google Tag Manager. Website: teplovoz38.ru
There are several problems.
1. The Measuring of Views of Product Details tag doesn't want to work at all. On the site itself, product details are shown on the product page, the Data Layer is set to pageview. In the manual, the settings are written for a click. Here are screenshots of the tag and trigger settings.
You need to set up a trigger to show the product page. How to set up a trigger? Are the tag settings correct?
2. Information on product impressions in e-commerce does not work in Analytics. The tag works fine when viewed in the debugger.
Screenshot of settings:
3. Checkout does not work. It is not clear here whether the problem is in setting the tag or the problem is in the dataLayer code.

Thank you very much in advance!
