Here's the story. I pulled out my b20vtec from my 97 ek coupe to my 96 ek hatch. When I pulled out the motor, I left the engine harness connected to my motor so that i dont have to connect it back up. When I put the b20 vtec into my hatch, I wired everything back up normally. When I tried to start my hatch, it won't start. It makes a very loud POP noise through my exhaust, and i dont know why its doing this. I have no check engine light either. anyone know?
