Changed the battery but not charging/turning on

My battery was staying at 1% even while charging and system preferences advised a new battery. I changed the battery, but now the computer will not turn on even if I disconnect the battery. I followed all the steps and used esd safe tools and I was esd anchored. Any suggestions about how I can possibly fix? I have tried a SMC reset but the best result I got was the touch bar flashes red once on two occasions. I have not been able to get it to replicate again.
