I tried to see if the pump work by connecting it directly, it doesnt seem to do anything just an initial click. So i wonder if the pump is out. Also i am getting sparks in the coils
that's pretty much the normal. It's not like your fuel injected vehicle where the pump buzzes for a second or two when you turn the key. If you test like above and you have fuel then I'd look elsewhere for your problem. As an "oh, by the way, your bike requires your battery to be darn near fresh and full to actually make the bike fire up. It's aggravating as heck, the bike will turn over all day, just won't start.

Sounds like you're getting closer though.

Did you test it while it was connected to fuel lines with fuel? If so then that initial click is fine and it wont continue to click unless the bowls are empty disconnect the feed fuel line to the carbs and have it end into a cup and then test the pump and see if it will continuously click and pump fuel without stopping
No i tested when i removed the pump outside of the bike. With the bottles and hoses connected no fluid moved.

Took the pump out of the bike, i was reading that the pump has 3 wires, but this one only has 2.

It lives! I clearned the carbs again. THey were really clean, but i re did it, this time i sprayed air into the carbs hoping something was in there. Then i ordered a new fuel pump, a chinese unit, but had a change of heart when i heard i could get a mr. gasket at advanced auto parts. Went there and nothing except a Holly fuel pump, i bought it for 50$. Installed it, and the bike roared to life.

I also had changed the oil, and the vacum hose that was disconnected i reconnected it, not sure which of those did it. But i think it was the fuel pump.

Not out of the water just yet, lots of work to do. But im really happy this bike is running.

the bike fires, yesterday it was running great. But now after bolting everything together it was running oddly as if it was not etting gas. Seems like a air issue. Removed the tank and the top plastic airbox and it seemed to run better. When i put the air box cover and tank runs like it wants to die

Sounds like a restriction in the intake area. Is there a rag sucked in to the intake opening under the seat or clogged air filter? Check the whole tubing and air box.
It may be too rich to begin with and with less air flow it affects the running. - ???

Here is a question for everyone. The pump works when i put power to it. But when its hooked up i dont hear anything, and when i loop the wire to have it continuously run, it doesnt run when the key is on.

when i jump this connector to get the pump to work continiously with the key turned on it does not do anything to the pump. Could the connector be faulty?

hooked up a gravity fed gas can to the carbs, and the bike runs perfect.

But when i hook up the pump no gas is being pushed up to the carbs. looping the 2 wires in the connector doest make the pump work, so im not sure what is going on. Any ideas?

The 3 wire relay is for safety, in case the bikes fall and engine quits, and the key is on, the fuel pump won't keep pumping fuel and cause a fire.
The blue wire to the relay comes from one coil to signal the relay to turn on the pump when the engine runs.
An electronic transistor relay not your typical coil and contacts type.

Been reading quite a bit about this, seems like a common issue. Still confused about bypassing the relay, was hoping to have a bunch of pictures to follow. Found this diagram on the website. And going to try and follow that for bypassing the relay. Thanks everyone, you guys really know this bike.

i hooked up the positive from the fuel pump to the middle relay wire, and then fuel pump negative to ground. when i start the bike it starts right up. But i cant find that yellow blue wire, because the fuel pump keeps pumping and pumping and fuel seems to be coming off the hoses on the top.

Today i replaced a few fuel hoses. Some were old and some had some cuts. The bike now starts and runs well as long as i bypass the fuel pump relay
