I have a 1995 Integra ls and I recently did and engine swap b18 to b18 but my battery now dies after I turn it off and it will only start when it's jumped sometimes it'll barely start right after I shut it off, I replaced the battery and it does the same thing do I have a loose ground ??

 

You need to do a current draw test. You need to have a battery fully charged in there and a good multimeter. Then with the car off and one terminal disconnected, measure the current draw through the battery post to the terminal. Check if it is withing spec. If it is above spec, pull one fuse at a time until you find the circuit with excessive draw. Then when you narrow down the circuit in question, you can figure out what specifically is wrong with that circuit.

 

What did you replace the battery with? A brand new battery or some other used one you're unsure even has enough charge to start up a car?

 

Alternator is good if you can jump start it. Sounds like just another dead battery to me.
