I recently purchased an 07 Chinese buggy. It has 800cc motor. While cranking it is firing the injectors. It is fuel injected not carbed. I hooked up a node light on the injector harness and while cranking it is firing the injectors. I have no spark coming out of the coil. I have power going to the Coil. I have traced the neg side of the coil back to the ecu, and continuity is good. When you turn the key to the on position, the fuel pump runs for 2 seconds and then stops. Then starts up again when you start cranking. But there is no spark coming out of the coil. Checked all the connections I can see, pulled the ecu main plug, and it is good too. Where else should I look?
