Hi folks new to the UTV world.  Someone handed me a 2013 Tracker 800-3 pulled apart and I'm now at the stage of seeing if it'll run.  Bit like getting a jigsaw puzzle with no picture.

Any way, it cranks over but the fuel pump doesn't run.  I can get it to pump fine if I bypass the relay.  So I'm guessing it's a ECU problem.  These things don't an ODBC connector which makes things hard.

Does anyone have any ideas (other than finding a dealer with an old PDA) how I can check what the problem maybe.
