Allgemeines Diskussions-Forum » ST3 Not Starting

We moved to a different house on May 8th and I had a hard time getting the bike to start. It sputtered while cranking but just wouldn't catch. On the third try, the bike fired up and I was able to ride it to the new home. The bike has been sitting since that day.

On the 4th of July I went out to ride the bike early that morning but it would not start. The instrument panel looked normal, and the bike cranked away, but would not fire. I tried several times until the battery was dead. Convinced it was the battery, I put it on the Tender and it took all day for the light on the Tender to change to green. After that, I went out and the bike fired right up, but I was too tired to ride so I just put it back on the tender.

This morning I went out and it would not start again. I tried six times. It would crank for about 10 seconds and then the starting cycle would end. Again, nothing unusual on the instrument panel. Unfortunately, I always wear ear plugs when I ride so I could not hear any noises the bike might have been making. I took off all my riding gear and went back out to the garage to look things over. I put the key in the ignition and turned the key. I could hear the relay under the seat but did not hear the fuel pump. I don't know if this is normal, but for as long as I can remember, the fuel pump made this "booo-eee-wip" noise when you first turn on the ignition. Now there is no noise at all. I checked the fuses (no issues) and swapped the relays under the seat. When I turn on the ignition, if I put my hand on the relay I can feel the relay click and then it clicks again after about two seconds. From what I've read in other threads, this should be normal. In another thread, Stick suggested looking in the tank when you turn on the ignition. I tried that and with an LED flashlight, there is no bubbling or any waves in the fuel.

So do I have a bad fuel pump? If I have to replace the pump, what else do I need? I'm guessing I should replace the fuel filter, in-tank fuel line (R10 hose from what I've read) and I should get the big o-ring too.
Please Help.
Thanks !

I didn't find the right solution from the internet.
