1986 Honda CRX new battery still won't start

I'm a single mom stuck at home! Please help.
My CRX ran great until a cold day in Nov. It wouldn't start and I'm pretty sure I ran the battery out trying (it needed a new battery anyway). I parked it for almost 2 mos and today put a new battery in. It is trying but still won't turn over. Isn't there a trick to it like pouring gas over something? I've tried starting it in gear and pushing it while trying to start it (in and out of gear, both first and second). My phone charger is in the work truck I carpool in and my phone is dead so I can't call the mechanic I use. Help!
