How easy is it to pull the plugs and check spark on a V7?
I read here about how easy it is to damage the plug caps, does that make them short out?
We need to see if it's sparking to confirm the rotation sensor is working, that tells the ECU to power the relay that provides power to the coils.

It's easy....VERY easy. And by now SS should have done it at least 7 times in 70k miles....at LEAST.

 Already done , no spark . Swede did say before that he was certain it had spark . Anyway , the bike has roughly 100K miles on it , the phase sensor was replaced at 50K , so likely it is do for another one . Antmanbee probably gets the cookie on this one .

 I still wonder why Swede is seeing some swirling in the gas tank ?

 We did that at least 4 times in the parking lot at Woolaroc in 2016 when the bike was being stubborn .

AND this is why we assume nothing during troubleshooting.  :thumb:

 Yep , was just going by what Swede was telling me . We had a long discussion last night about this problem , along with a discussion about philosophy and history . You might be surprised how many bikes get fixed over the phone , even more surprising is how many calls I field every month where we come up with a solution  :shocked: Ask fubar .

So please enlighten us, how did you come to the conclusion it was a phase sensor?

 Loss of of spark and fuel apparently at the same time . Antmanbee sussed this out .

You guys are so fantastic!   I posted a random question and then wandered away, and you guys are all continuing to diagnose and cogitate even though I haven’t reported back.  Thanks.   

I only have sporadic time to fool with it.  But here’s the status as of now. 

Battery is fairly new.  Starter motor cranks vigorously.  So strong crank but no start.  Battery being recharged now.

Kill switch, side stand switch, etc. have all been toggled.

All fuses good. 

No fuel being injected.  Spark plugs are dead dry. 

No spark.  It wouldn’t start when I sprayed starter fluid into throttle body.  I also pulled right side spark plug, grounded it to head, and got no sparkles.

No swarf on head of cam phase sensor.   And in honor of Paul, using my Boy Scout compass, I have pointed the front wheel due North, due South, and due West and East.  Still no start.

My hunch is it’s a bad cam phase sensor.   My original one crapped out at 50,000 miles with the same symptoms, and I’m at 91,000 now.

When I get time I’m going to remove the tank, De-Oxit all connectors, including the relays.  Maybe switch relays around if that’s possible.  Ohm out the cam phase sensor.

Yes, the red wire feeding the coils and injectors is dead, there is also the possibility it's a bad relay, the coil should read in the range of 100 - 120 Ohms

Ok, just to close this out, the problem was a bad crank position sensor. 

I’m going to start a new thread on this topic
