FI codes turns over will not fire up

[vans4455]

I just got a 99 gsxr 750 fuel injected model . I road it a few times ran just fine . I went to ride it last night fi light started flashing no start??? Codes where 13-14-21-22-23-24 didn't find a 13 code anywhere so no clue wat that is.. looked over wiring harness from wat I see no cuts rubbing it brakes in the wires , checked plugs none are melted. Disconnected batt put back on fired up for 2 seconds shut off and all codes came back ??? I'm at a loss here, spins over but won't fire up .

check your connectors at the ecu

If you're ECU is unplugged it'll turn over and not start... with that many varying codes that'd be the first place I looked. You might be unplugged or have some wires cut/pulled out of the connector.
