I had that same problem after replacing my clutch check your ground that leads to the Negative side of the battery to chassis and to transmission. I would really inspect it if it’s dirty or loose connection.I just put back in a transmission in my 2000 Integra LS Skwa auto with a used skwa. Got everything in and went to start and it cranks but no start. I have no spark. My key light doesn’t light up neither does my cel/mainreq and oil light when i have the key turned. Had the car sitting for a little over a mount.
