My 2014 Honda CB500X, (35,000 km, always serviced when due) won't start this morning after removing the fuel tank last night. I'm pretty sure I followed everything in the service manual except some of the inspections that need special tools but I don't have too much mechanical experience so it's not impossible I messed something up. I had to strip the bike down a fair bit, and removed the fuel tank, including fuel pump cable, fuel line (quick connect type) and breather hose. I also opened and tried to remove the air box, but couldn't get to some of the bolts and reassembled it. I don't recall unplugging anything else and can't see anything, but it's not impossible. I plugged everything back in and tested the bike last night before putting the fairings back and it ran fine (I only ran it for about 10 seconds), but it wouldn't start this morning. I hear the fuel pump run when I turn the ignition on and the starter runs fine, but it won't fire. While trying to start it the fuel pump runs too until about half a second after letting go of the button. To get the obvious out of the way, the kill switch is off, the side stand is up and it's out of gear (it only doesn't start if it's both in gear and the side stand's down). I think the next step is to disconnect the fuel line again and test the fuel flow, but the service manual says that a seal and a clip should be replaced every time it's removed so I'd like to minimise that for the moment. I'd call my mechanic but he's on holiday at the moment and I can't find any others in the Western suburbs of Melbourne who would come out Does anyone have any suggestions?
