Yeah, I bought one of those ebay pumps, will be installing it this weekend...

So I sprayed the fuel and it almost started which tells me fuel is not going through. How do I test the fuel pump? Anything else I should check?

OxyG3nE you may have corosion in the connector . The connector is locator inside the electrical tape close to the fuel tank wire.

Thanks. I'll try that this weekend. I had forgotten to mention that I just changed the plugs. I have a feeling it's the pump, I had the same issue before I changed them and I was hoping that would do the trick...

One more thing I failed to say, I was jump starting the bike with my car battery. I just read that jump starting a bike with a car could cause a spike and some bikes have a microprocessor that are sensitive to Voltage spikes. I need a new battery...

I'm not getting any codes. Can you check it with just the ignition switch on? I haven't checked the fuse; I'll check it tomorrow.

Just to know any error code
