2007 Civic EX Cranks, no start

So, a friend of mine had her Civic just die out of nowhere while driving. They had it towed to my house and I ran some quick diagnostics on it. Can hear fuel pump, I’m seeing RPM in my scan tool, all sensors look normal but it won’t fire. So I shot some starting fluid down the intake and it fired up and died right after. So I was like great, weak fuel pump. WRONG, this thing still won’t start. I checked the fuel pump relay under the dash and the 2 PGM-FI relays in the fuse box by the driver side tire. This thing is driving me nuts! Checked all fuses as well. I can’t seem to figure this one out.
