I’ve purchased a 01 ZX12R. It had been taken apart years ago while fully functional and running great. (He thought it was being repossessed) it was never reassembled. Fuel tank and pump rusted out so I’ve replaced both. It’s acting as if it’s getting no fuel. I poured fuel directly into throttle body and she fired up!! Any suggestions on why she won’t start on her own? Thanks in advance y’all!
