wussup! i got an eg with jdm b16. i took out the old wiring harness replace it for new one, the motor turns but doesnt have any spark?? so i put the old harness back on and still the same problem?? i checked make sure everything is plugged in and still nothing.... i appreciate any help! thanks!

 

Is the ground wire on the thermostat housing connected?

Do you measure 12V at the distributor coil when the key is turned to ON(II)?

 

yeah the ground is connected, and i havent checked the distributer yet.... ill check that out thanks

 

This seems obvious. Re-check all of your wiring. If it started before you changed harnesses, the answer lies in your wiring.
