I tried the tank on my other battery and it works fine. I think it just the pin won't stay up

Hello I am a little new to mods and I bought a cool fire 1. The battery works fin so dose the tank but the pin won't stay up after I lift it a little with a flat head! The battery works fine but when I put the tank on it won't evan turn on! I'm upswing the original tank too. Any ideas?
