Question about 1989 Yamaha FZR 1000
Bike will run when you feed the fuel direct into carb
1. fuel pump not working?
2. Is there a relay?
3. Is there a fuse?
Any info please
It seems likely that your fuel pump is not operating, you should hear the fuel pump priming when you turn on the ignition, if not the fuel pump is at fault, this is not uncommon and a replacement is the answer.

I'm not sure about yamaha but suzuki has a vacuum connection on the fuel petcock that turns off the fuel flow if there's no vacuum from a running engine. check that all connections to the petcock are secure, the vacuum line should go back to the carbs. If you put the petcock in pri(me) it defeats that and the bike should run but the carbs will flood if you leave it for any length of time
