No fuel to START...on intermittent occassions...
Hey guys. In the middle of trouble shooting an intermiitent starting issue on an 08 V with only 5K. [Yeah, I am ashamed but mitigating circumstances]
Super condensed version... Over a 3 to 4 week period last summer, bike would turn over fine, good voltage/charge on batt but not start. This happened 5 or 6 times.
Bike WOULD run flawlessly [once started] as it had since I bought it. The very first time it happened the bike had sarted, ridden just a quarter mile and parked 5 minutes. I was at work. I did nothing but wait for an hour. It started right up. About a week later it would not start at work again. Waited an hour and ran the battery down trying to start it. Put batt on a charger. Twelve hours later back at work and it starts. Four or five days go by with numerous hot and cold starts. No problem. Maybe 4 or 5 days later at home, won't start. Batt checks at 12.84 volts. One shot of starting fluid later it starts and runs flawlessly as always. Problem "solved". Sorta. The starting fluid goes with me... and always fires the bike almost immediately 3 or 4 more times maybe every 10th start or more for the next couple of weeks. Then, won't start even with the fluid. [at home luckily] I pull the tank, empty the remaining gas [looks good] pull and inspect fuel pump and filter, both look great. Reinstall tank with fresh fuel and still won't start with or without starting fluid. $#%@$#*#$%
It stayed parked since then until yesterday when I decided enough was enough. NEW battery charged and installed. Pulled tank again, rechecked pump/filter and decided just for grins to install new pugs. What the hell... Old ones looked fine. It now sarts with the staritng fluid but won't run. I tried with the gas cap open and still no dice although last summer all through the problems it obviously was not a venting issue.
I thought I would check with you guys for any thoughts before I pull things apart again and start checking relays, injectors etc. I did only put ONE gallon of fresh gas in, in case I have to pull tank again. Certainly that would be enough for pump to prime it would seem??? The next step is obviously to check fuel output and pressure...
One thing I did not mention is that I don't have an idiot FI light and that I ALWAYS hear the pump prime up on every turn of the key although it has always seemed closer to 2 seconds than three to my ears from day one.
