ECM Needed

I am pretty sure I need an ECM. My 2006 ABS model cranks, but no spark. This morning I installed a perfectly functioning coil. Still no spark. Damn.

What part # is on the tag of your original ECU? And, as long as you have the ECU unplugged & removed to find that tag...

Why not use some form of electrical contact cleaner to, um... clean the contact pins on the ECU and the wire harness?

While you have the contact cleaner out, give the kill switch a good blasting bud.

In my SW-T600 when kill switch is on, fuel pump does not activate. Setting kill switch to off, fuel pump activated and HISS light and engine light come on for about 2 sec. This way you can test kill switch.

There is two sensors CMP sensor and a CKP sensor. I think both send infos for ECM.
This sensor is installed to cylider head 36140MCT003 , and other is under alternator/generator 30300MCT000. You can test these with multimeter. While cranking scooter, you can read 0,3-1,0 AC from multimeter.
