Stock ecu, stock intake, stock headers and exhaust. I just change the spark plugs and found that i'm not getting any SPARK. The crazy thing is before i took off the turbo kit it was working fine, now no spark. I Can smell the gas and it turns over fine. The battery is new.

Is the stock ecu the original one that came with the car? Or is it a new one? If it's not the original it needs to be reprogrammed at Honda to start the car

I had the same thing go wrong with mine when i went from turbo back to stock. I left my 4bar mapp sensor on the intake and it would not start. I put the stock back on and it started right up. The wetness your seeing on the plugs is fuel because its not starting. Its the sensor on top of the intake manifold , right at the front of it where the piping starts. The stock one is black. BUT there may be an aftermarket one that black also. You need to take it off and post a pic of it so we can tell you if its the stock one. But im sure thats it.

Did u unplug the connector to the coil to see if ur getting voltage there? Should be close to batt voltage.

No the map sensor is stock and i'm using the original ECU from the car. I'm thinking it could be the CPK (Crank Pulley Sensor) that has gone bad. Not sure though yet.

I even tried putting the AEM EMS back in with no spark still. It has to be the motor.

What are the logs on the ems saying?
I am sure the aem will be able to tell you what every sensor, injector and coil is doing.
Use it for troubleshooting?
