NGC Kawasaki Vulcan Nomad still no spark???
« on: February 21, 2020, 11:52:56 AM »
2000 Kawasaki Vulcan nomad 1500 fuel injected. Has no spark at spark plugs when turning over. replaced pick-up coils, primary coils, tested kill switch, sidestand switch, and neutral switch...all good. No reading from the bike down switch so don't know if is good or not but it is being replaced to make sure. Still no spark at plugs. Could ECU be the problem or a loose wire? Bike was running for a minute or two (idling) in garage and just stalled. No spark at plugs since. Whats your guess??  Im getting stumped here :angry:

 It is broke. Send it to see and I will dispose of it for free.

Does it have fuzes or breakers?  Something could be tripping to cause it to kill the spark? That's a four cylinder? So it's got to be something killing spark to the whole harness, like a short tripping a breaker or a blown fuze.

Have you checked the 100ohm resistor in the ignition switch?   

From what I found on the interwebz, it won't run without it.

I posted same question on a Vulcan 1500 forum.  I just thought I would try here too.  Sorry if I shouldn't of.  Have a nice day!

All wiring behind ignition switch seemed all in order but I will try to find the 100ohm resistor also.  Thank You

 No problem with asking here Bob , was simply curious is there is a Vulcan forum .

Im checking that resistor on ignition switch next.  From what I can tell if that goes bad it would cause the bike not to start (as being hotwired/anti-theft function) but would NOT cause the bike to stall if the bike was already running.

My scenario is the bike was idling fine in the garage and then just died, with no spark at plugs or fuel pump priming (Fuel Injected) after that.  Fuses all seem fine.  Something is causing it not to fire and I will continue this long trip to ?????   Its a friends bike and Im trying to help him out as he cant afford the dealership labor rates, and one of them told him they wouldn't work on it anyways because its too old (2000).  Oh boy...….

Hey Bob, I feel for you, it sucks when a bike is throwing monkey wrenches at you, doubly so if you're working on a strange bike and aren't familiar with it or it's history.

     I'm not electrically inclined or familiar with that model, but I'll throw a few thoughts your way.

     Iirc, that model is known to be relatively reliable; unless previous owners have mucked up the stock wiring harness with sloppy add ons, ie, power ports, driving lights, alarms, heated grips & vests etc. I'd pop the seat & side covers off and raise the tank if possible and chase the wiring harness and verify the integrity of it.

     While you're doing that, you might find a second fuse box, short, loose connection or hidden ground that should be cleaned.

     Verify all connections and grounds with deoxit, and just for fun if the relays are compatible, I'd flip a few around to see if the symptoms change.

     Verify battery connections and condition, these modern machines are fussy on the voltage and power they get.

     I gave a boost to a stranded modern snowmobile this week, his machine & display lit up with the ignition on perfectly, but other than the perfect Christmas light show on his dash his machine was completely dead; I gave him a boost, it started and off he went, it just needed that little bit of extra voltage to get the EFI and ECU to work,fyi fwiw.

     Sending patience and thoughts your way

     Good luck

If the fuel pump isn't running, all the spark in the world won't help.  At least as you trouble shoot it, you can just listen for the pump to prime instead of fooling with holding a plug against the cyl. head.  Does the rest of the electrics work when you turn on the key? (horn, lights, turn signals, etc.) or is the whole system dead?

All other electrical systems/functions work as they should.

Thanks for the info and good luck wishing!  I’ll find the cause of the no spark no fuel pump issue sooner or later

sparklers and fuel pump(after prime)need to signal the ECU to lite the engine Cam and or crank sensor. try wiffing some brake cleaner across the intake. that will show that if it fires it's fuel pump issue. you should hear the pump run/prime for 3 sec. on key on

I ran 12 volts directly to the fuel pump to check it and the pump ran without an issue. Its like something electrical is shutting down the spark and fuel pump.  Im going to start checking every wire connection and grounds next.  Tedious job!

Does that model have the famous junction box, or, "j box"?
If so one of the relays inside may be stuck or  the circuit may he open. Rap on the box If so equipped. See what happens.

I don't believe this one has a "jbox" but in checking each and evey wire I will find out.  Time consuming here.  Lol.  Oh well, I gotta get this fixed for a friend so he can ride again so I gotta keep at it.....

Bob, if you have a kal dealer it may be acceptable to just take it to folks who has probably seen this issue before and can ID and  fix the problem. Sometimes we just have to bite the bullet and let someone else take over.

The local dealership and one other said they won work on the bike because it is more than 10 years old (2000).  Thats crazy isnt t?  So its me or nothing.  lol.   :drool:

You know there is no prime cycle for the fuel pump when you turn on the key. Assuming there is sufficient voltage to trigger the system, work backwards from there and check everything that signals the fuel pump or nixes the signal. What kind of switch signals the bike is down, and can you run a jumper around it? The side stand switch will only interfere if you are in gear- is the neutral indicator working? Is there a signal to the fuel pump relay when you turn the key on? Narrow the options, and  backtrack systematically.

When cranking over the engine, only do so for less than 5 seconds.  Turn off kill ignition, turn back on.  The ignition control module will go into limp mode after cranking more than 5 seconds.  Giving no spark.

We did take it to an independent shop.  They had it for three weeks and said they could not find the cause of the problem, after replacing pick-up coils, main coils, and checking downed bike switch, clutch switch, kickstand switch, kill switch.  Im going to start tracing each wire, trying to check ignition switch and in-line resistor, and keep checking best I can.  Thanks for all the ideas

Owner told me he always heard fuel pump cycle on when key was turned on.  Doesn't now and no spark at the plugs when turning over engine.

Bike down switch showed no readings at all, im still checking that issue.

Neutral indicator does work

fuel pump relay I will check again but pretty sure it was getting voltage and clicking when I checked it three months ago.  Cant remember so im checking everything again. Starting over from replacing battery as its voltage/ability to hold a charge is getting suspect with all the cranking that's been done over last few months by independent shops etc.  Thanks for ideas

 Is there something like Kawasaki diag ? That's why I asked if there is a Vulcan forum , or ask over on ADV rider . If information about a specific motorbike is needed , going to where the experts on that bike hang out would seem to be a good plan , right ?

I wish you were close by me in central NC. My mechanic and good friend is a 43 year certified Honda mechanic but has worked on every brand through out all these years. When he worked at the last Honda business before retiring he did all the electrical trouble shooting in the shop because he was the most experienced and actually liked the challenge of electrical issues. I’ll give him a call and run by all I’ve read here about your problem and see if he has any thoughts.
To make sure I understand, there is no spark at the plugs and no power to the fuel pump, right???

Yes Sir that is correct.  All other electrical components work fine.  All switches, (Kickstand, neutral, emergency shutoff, neutral, bike down switch) have been checked and work as designed)
