My fuel pump wasn't working so I went ahead and scored a new one for less than $40. I ride a 98 honda cbr600 f3. I installed the new pump and still no gas in floats... No noise, clicks, vibrations out of either pumps.. I used a multimeter and check my batter and had 12.5v, battery low of 10.9 while starter is engaged. Check the 2 tabs that the pump connects into and didn't get a reading with the key on! Is there a fuse I don't know about ? Or something ? Help !

 

Do you have the fuel lines hooked up correctly? Its a low pressure pump, you should still be getting fuel to the carbs.

 

Yes.. The fuel pump isn't operational !

 

If I remember correctly, those pumps only work with the bike running, and the just pulse every so often at that. You could always bypass it and go with gravity feed to test.

Petcock open? Some models need engine vacuum to open. Not sure if you have that kind or not.

 

Demon is correct. Our fuel pump only works when the bike is actually running. Also like he said you can totally bypass the pump and the bike will run.
If your bowls are totally dry, I would say you either have your hoses reversed at the fuel pump, a hose crimped somewhere, a clogged line or a bad petcock. Asking a simple question, you do have the petcock in the correct position, right?

 

Yes the Petcock is in the right position! But guys I wasn't getting 12v at the pumps leads I could have put the pump the wrong way I'll check soon. How is the pump suppose to prime gas into my carbs when there's no gas to begone with to start the bike !?

 

It doesn't. It just helps feed the bowls when the gravity flow is low. There should be more than enough fuel in the bowls the start the bike.

 

+1 on what demon said. gravity does most of the work and the pump assists.
i would start with the basics.
1st pull the fuel line off the petcock. if fuel comes out, the go to the next point, etc..

 

With the fuel pump attached the bike won't start, no gas gets to the bowls, I bypassed the pump and I can get it started. The bike sounds different tho, revving up it sounds way different, and after I release the throttle the rpms drop but then it idles high and then goes down after a few seconds, could this be because I didn't screw in the jet right after cleaning ?

 

it sounds as if you might have the hoses swapped on the fuel pump. Another possibility, (depending on how you bypassed it) is that your fuel filter might be totally clogged, but I doubt that.
To your other issue, there are a couple possibilities. 1st there aren't too many ways to install your jets incorrectly. one of the things to keep in mind is carbs 2&3 have 138 mains and 1&4 have 135's. But even if you have those messed up, it wouldn't keep you bike from starting.
There are a couple things to look at. 1. your pilot screws should be between 2-2 1/2 complete turns out. You can mess up the install of them. It should be o-ring, washer, spring, with the 0-ring being the outer most thing.
Another thing is idle adjustment screw. If everything is stock, if you start with that about 2 turns out, that will get you started.
Not sure if you separated the carbs when you cleaned them. If you did, that's a whole other kettle of fish.
