I have a 2007 Suzuki Gsxr 600, wont get spark, fuel pump wont prime. Any help is greatly appreciated. Here is where it started. Left for a ride was smelling a rotten egg smell, later realized it was my battery when I stopped, all swelled up, went to start it and wouldn't. I was a good ways from home so I push started the bike, (which I regret on a level you cant imagine). Got a good ways and lost power, rpms on gauge slowly dropped. After a long night on the side of the highway finally got a friend to come with a trailer. I get it home narrow it down that ecu is blowing fuse every time I turn key, so I buy a used ecu off ebay, new regulator, new battery, hook everything up, turn key fuses good cluster reads N only. Cranks over but wont fire up. Checked spark plugs no spark, fuel pump wont kick on, normal headlights wont work, brights will. Only sound when turn key over is coming from under the air box the valves under there moving that is it. Is it possible that I bought a bad ECU? They are saying it came from a working bike, is it possible my wiring is fried some where. Seems like im not really getting power to anything, this is my first bike learning as I go and Ive come to a dead end, I want to test this ECU I bought but I dont know how. Pls help my Gixxer.
