My girlsfriend's 17 year old bought an 06 Sportsman 500 EFI a few months ago. He didn't ride it very much before it quit running. He recently brought it over to me to take a look at. I am not getting an spark or fuel pressure. I have pulled the fuel pump out of the tank and it will run with jumper wires off of the battery. I am getting 9.5v at the A and C wires at the connector, with the key on and off. The dash lights up with the key on. He replaced the module up by the radiator. I removed the ECM yesterday and if you shake it, it rattles. Did a circuit breaker brake off? This machine has had a hard life by the previous owner. As for no spark, I see the thumb throttle contacts are closed. I'm going to adjust the cable so the contacts are just open. I have tried to check for wiring harness issues, but maybe looking in the wrong areas. I need to pick up a service manual. Where is the best place to get one? Thanks for any assistance.
