I have a 06 triumph 675 will not get initial crank I have to use starting fluid to start the bike and after started will ride all day as long as I don’t shut it off or kill it, new spark plugs, new battery put a new fuel pump in it, cleaned injectors and rail, checked crank sensor and I’m at about 200 resistance any help please I am a car mechanic just lost on this one
Thanks mate, I don't know what WFAFN is, so I tried to Google it... I've probably triggered some MI5 Nazi alert now, as Google auto-cockup changed it and I got this...
Hoping to shorten 'Welcome From A Fellow Newbie' to 'WFAFN' and eventually just 'W' to save finger crut (if the forum agrees).
Hi Derrick and welcome in I'm not mechanically knowledgeable, so this is probably no real help with your problem, but the idle does seem low, my ST 675 (and others I've seen) on start idle at about 1800 rpm. Apparently the idle speed can be adjusted via the ECU (TuneECU ??)
https://tuneecu.net/ - You need a Windows laptop or Android tablet, the software, and a compatable cable (about £16 or $20 ish). It is discussed on the Triumph675.net forum here: https://www.triumph675.net/forum/showthread.php?t=51572
Initial enrichment is failing. Does the bike know it is starting? I am not specific on this engine management system, but I do a lot with industrial controls. I think about how the ECM knows to give more fuel on start? Found this on other site: https://www.675.cc/675/threads/puls...rank-position-sensor.20693/page-2#post-408875 Seems your resistance is within tolerance. I would think about starting routines in ECM and how it knows to trigger.
Yea I read that post it’s mostly about the cps and I got good readings but connecting to ecm is my problem
