I have replaced my stock F54 with a N42 carbureted engine. I have removed the EFI harness and components. the car ran fine till I had no break lights . I removed stop light switches under dash and now I have no spark. I have power to coil but no spark. I am buying a new distributer and need to know witch setup I should buy.

 

81 zx with n42 carbed.
the car runs rough. when I pull the plug wire away from plug and hold it about a 1/2 in. away. it starts running right.

 

Replace all the spark plug wire, dizzy cap and rotor then start trouble shooting..
