89 cbr600 no start
Hello Everybody!
I just bought my very first bike. It is a 1989 Hurricane? I am having trouble with my fuel system somewhere.
When I turn the key over it doesn't seem like my fuel pump is kicking on.
I do not know where to start! I was hoping that if anybody else has ran into this issue could maybe give me some guidance?
Or maybe if there is a post that already addressed this, a link to it?
I have heard of zener diode but when I took my ignition off it didn't look like there was even a place for it on this bike.
Any help or direction is appreciated! Thanks in advanced!

This is a carbureted engine, not fuel injected. The fuel pump only runs while the engine is being started or the engine is running. When was the last time this bike ran? Provide as much detail about what is happening so that folks on here can help.
The previous owner had it running about a year ago but it has sat since. He couldn’t figure out why it stopped running and gave up on it. I unfortunately do not know much more beyond that. If I spray ether into the carbs she fires up like a champ but no power is getting to the pump. I tested the pump by jumping the wires and it works that way. Hope any of that info helps
OK, yes that helps. I would not focus on the fuel pump. If you open the drain screws on the bottom of the carburetors, does fuel come out? You can bypass the fuel pump and feed the carburetors directly from the fuel petcock. Not good for high RPM, but ok for starting and testing. My best guess is that the carburetors are going to need to be pulled off the bike, disassembled and cleaned thoroughly. This is a common issue for a bike that has sat for a long period of time without running.
Yes it does run when you do that.
I am still confused as to where my issue is with not getting power to fuel pump. I feel silly because in my head I know there is something ever so simple that I am over looking.

Ok, I don't know the 89 600 that well, but I'd be willing to bet that it's wired the same as the F3's. The voltage that is applied to the fuel pump is only on for brief periods. It's tied to one of the ignition coils. So the only time that power is going to be applied is when the engine is actually being turned over by hitting the starter button, or when the engine is actually running. Even then with a regular meter, you're not going to read 12v to the pump. It's going to look like it's fluctuating (which it is since it's turning on and off). If you have a meter that can capture Peak voltage and display it, then you'd see the 12v. If you have the manual for that bike, there is most likely a section on doing a discharge volume inspection. I has you put a jumper on the connector of the Fuel Cut-Off relay, which will provide continuous 12 v to the pump. Keep in mind though, that if your engine is not running and fuel is not being consumed, the pump will stop as soon as pressure builds up in the lines.
