No tach or DLC connection

05 civic ex. I changed the gasket but when I first tried to start it would start for a second then the RPM's would drop to nothing. I figured the timing was off. I let it sit for a couple days with the battery unhooked. Today I hooked up a scanner and it won't connect which was never a problem before. It started and ran but kinda rough. But now the tech didn't move at all and when I tried to rev it it would only go to around 1500rpms (guessing since the tach isn't working). Cam and crank sensors are both new and connected. Any help would be greatly appreciated.
