Changed the ecm and stator but still no spark

Yes, the ECM is the last thing to replace after all other possibilities. No spark could be bad ignition coil, bad Ignition Control Module (controls the coil circuits for spark), bad plug wires, the crank and cam sensors (for ECM to determine spark timing).

Check the ICM -it can be tested at a parts store. If good, check the crank sensor.

See if you can get one of those shops to "reflash" the prom in your ECM.

Stator should be producing AC power to a regulator. Check to see if you are getting any DC power to the coil. Bring DC power to the coil positive and then ground the negative and then when you remove the negative from the ground the coil will spark from the secondary wire to ground once each time you ground and remove the ground from the coil primary circuit if the coil is any good.

Could be the CDI. Check the stator and pickup coil specs with a multimeter first.

i think u goto compretion test.

I would make sure you have voltage to the coil. Could be a fuse or relay problem. Is the check engine light on when you turn the key on ?

only missing the cables replacement

I have seen through experience and not just from hearing that it was a bad crankshaft position sensor even without a DTC of P0335. Also a bad ECM relay has caused this. Yes I know if the relay is bad it's bad but have seen it. Below are the testing procedures to test the condensor and the relay. If these test out good I would go to the crankshaft position sensor but before you start buying anymore parts find the problem then fix it. If you need anymore testing procedures feel free to email me at [email protected] and I will be happy to help. Now you're positive you have checked all grounds and any open circuits ? This is the most common cause that's why I ask. I hope this helps and good luck.

check the side stand relay>>>

You said you changed the ecm module, is that the ecm or the ignition module. Do you have access to a scanner to check cranking rpm? That way you can test the new crank sensor and the wiring and the ignition module.
