So the ABS light on my 2007 bike was staying on...
It gets worse.. gave it a break, checked starting... kicks over but not firing up. not starting plus abs light still on.
Dave, You mean the starter is cranking, turning the engine over, but it does not run now?
Interesting, frustrating I am sure.
Basics: Squirt, suck, squeeze, bang, blow. Repeat.
I'd start with spark... what a PITA to even get there!
Go back over everything you fingered, check the fuses and any electrical connections you messed with.
Let us know what you find and how you get back to base line please.
I can't imagine.
