Default [Q] gmail syncs all but mail

I am having trouble getting gmail to sync my email for a particular account. I have 2 gmail accounts sync'd on my phone one works flawlessly the other syncs everything except the mail. When I go under system settings and look at accounts under gmail, it shows syncing and it stays that way. Phone gets hot and battery drains real fast. Battery stats show gmail using all of the battery. I tried clearing gmail cache, rebooting into recovery and clearing cache, reducing the amount of days for syncng and nothing seems to work. I have googled this issue and tried what I could find, nothing works. My email works in gmail.com just fine. Phone also is not running out of space. Any ideas?
