Posted February 23, 201213 yr hi there, so its not a yamaha, but im hoping someone on here could help me a bit? i have recently bought a gilera runner purejet 50 2004, as a project (sorta) i was told all that needs doing is a new ecu is needed, because the other one burnt out, so i got it home took the old ecu off, went on ebay and bought a 2nd hand one (description said fully working) and put it on the bike, the bike fired up first time but then, i took the battery off to charge it because it was going flat, i took it off put it on charge and left it for the night, next day came out to the bike put the battery back in, turned it over, and it wasnt sparking? i noticed that the engine management light was flashing.. ive checked the wires, there all intact, im really looking for some suggestions of what to check, is there any way to check the ecu? thanks. kyle.

February 24, 201213 yr Author put the ecu in a friends bike, and the bike started first time and if anything went faster -.- it starts on engine start, so i think it might be the injector?
February 24, 201213 yr If thers no spark , it will be the earth, as you took battery off, & was fine before that , check the earth from Ecu, Had this prob wiyh a Starfire ecu,
