If it is not crawling, either your site already has a penalty, or your content is simply not good enough, or there's just no link linking to your site, thus, there's just no way the search engine will be able to find your site.
Or if your site has no penalty, content is good, but has no link linking to your site, then you can try submitting your sitemap to G and let their crawlers do the work for you.
Or if you dislike submitting sitemaps, then submit your site to an instant link indexing service, which should be able to index your site within 8-24 hours time. If within 8 hours, your site should be quality, if 1 week, then the content is not good enough.
