I just recently got a Joyner renegade 800, 2008 in a trade, it has issues though. So the fuel pump and fan were not coming on, the previous owner had hotwired both so he could still drive it. After working for a while it just stopped working all together. The previous owner said he thihis it's a bad ecu but before I go spending 700 on a new one thought I'd ask here.. Has anybody had this problem or might be able to lead me in a different/starting position? Thanks.
