Guest Bursledon-Mark Posted February 18, 2004 Posted February 18, 2004 As a proud owner of a new a Burgundy V11 Sport Naked (albeit 2002 model at a steal of a price), I’ve been reading the board with great interest and thanks for all the info I’ve picked up from you all (and a few laughs along the way ). Since collecting the bike I’ve had, intermittently, “No Wrrrrrr fuel pump / clicking relays” when trying to start the bike. This usually occurs after stopping after a short while (normally for a cigarette …… maybe I should just give up smoking! ). Initially pressing the kill switch a few times did the trick; on one occasion pushing the bike up a hill in preparation for bump starting cured it. I mentioned this to the dealer on the first service who “couldn’t find anything wrong”. Looking though previous posting I convinced myself the relays where to blame so recently replaced them with the Bosch units. Initially this appeared to resolve the issue but alas the problem reared its ugly head again. Ive checked the wiring under the relays and all looked OK (well nothing was loose). What confuses me slightly is following approx 20 mins of re-seating, putting the sidestand up and down and hitting the kill switch as few times seems to get it back to life which led me to start believing it might be a faulty connection with the sidestand cutout but if that was the case I would think that you would still hear the Wrrrrr of the fuel pump etc but just would’nt be able to start it ………………and the same with the vapour lock issue ………………………. Or have I read to many threads and confused myself PS - Im from Southampton, England ........... dont know what happened to my location!
V11UK Posted February 18, 2004 Posted February 18, 2004 Confused of Yorkshire here... Welcome Mark. Have you checked the clutch switch on the handlebars?
Guest Bursledon-Mark Posted February 18, 2004 Posted February 18, 2004 Well by checking .............. I gave it a squirt with WD40 and a wipe over, if I listen very closley I can actually hear it "click" aswell If it was anything to do with the sidestand switch would this cause the fuel pump to not start / relays to click though .............. this is where I get confused !
Guest PAULSMART Posted February 18, 2004 Posted February 18, 2004 RELAYS!!! - Its always the relays. are they made by Siemens ?? If so swap them for bosch ones. try a search on this forum and you will be able to get part numbers, to help source them cheaper, expect to pay approx £30 for a set. Try swapping a couple around to see if original problems dissappear. Paul
Guest Bursledon-Mark Posted February 18, 2004 Posted February 18, 2004 I've swapped them for the Bosch ones hoping that would solve it ...... but it didnt, in addtion to swapping the replacement boash ones around.
Mike Stewart Posted February 18, 2004 Posted February 18, 2004 The next time it happens to you, try doing this. While on the bike with clutch lever pulled in, push on the starter button and turn the bars to lock to lock. If the bike starts, your problem is in the clutch switch connection located under the fuel tank. Just by moving the bars moves the harness ever so slightly and is enough to make a better connection. On both of my Guzzi's, I have bypassed the sidestand and clutch switch. Good luck, Mike
docc Posted February 18, 2004 Posted February 18, 2004 Another simple one to try: Tighten the bettery connections, they notoriuosly get loose. Also check the voltage with a digital meter. If it is not 12.7 v the battery may be up.
Guest Bursledon-Mark Posted February 18, 2004 Posted February 18, 2004 Thanks Guys ............ I'll check the battery connections, and the battery in general ........ due to the weather we have had over here since I got the back it has tended to sit around for a few weeks between rides and saying that Im not sure the problem was so regular when I havent used the headlight. It still puzzles me though re the answers about the clutch micro switch. If this / coonections where a little "iffy" would'nt you still hear the fuel pump start up / relays click prior to trying to start the bike
callison Posted February 18, 2004 Posted February 18, 2004 It still puzzles me though re the answers about the clutch micro switch. If this / coonections where a little "iffy" would'nt you still hear the fuel pump start up / relays click prior to trying to start the bike You're right. The clutch switch will prevent the starter from turning and nothing more. If the fuel pump fails to energize it is more likely to be a relay. Except... the power relay for the ECU has a single inline connector to it in the harness V11 Sport schematic and that connector - #57 can get just enough resistance in it from contact corrosion to fail to allow enough current through to activate the relay. It can still pass just enough voltage to give a good reading though which will confuse the merry hell out of the none electrical types among us. It even stuck me on my Sport 1100i and I've been an electronics tech for the better part of 35 years. So, it is another possibility, and not necessarily the main culprit, but you can find it, and disconnect and reconnect it a few times to wipe the contact surfaces and remove it from the list of possible suspect areas.

On both of my Guzzi's, I have bypassed the sidestand and clutch switch. This has just started happening to me, I thought it was my relays until I tried what you suggested. However, my connectors look fine, it's gonna take a lot more diagnostic skills for me to track it down. Wrrrrrring is fine, just (sometimes) won't turn the starter motor until I move the bars. I want to keep my clutch and sidestand switches operational, and my neutral light one too when a replacement finally turns up. BTW, where is this connector #57 located, Carl? Under the ECU relay?
docc Posted February 21, 2004 Posted February 21, 2004 Connector #57 is under the relays. It may require dropping the fender liner to access. Check this thread for : connectors for the clutch switch
Guest Bursledon-Mark Posted April 5, 2004 Posted April 5, 2004 As an update to this ......... I bought an Optimate battery tender and have left it hooked up to the bike when not in use and Presto no problems since that day. Starts first time every time
