F4i problems.. help!

I've had my 01 F4i for 1.5 yrs now and just recently ran into a problem. She won't fire. It turns over, but just won't fire up. I took the plugs out tonight and they don't seem to be fouled. I pulled in the garage one night and it just cut off. It hasn't started since. Any suggestions??

This has got to be a fuse, switch, relay, or ground problem. I would recomend finding a service manual and just start checking things one at a time. There are lots of potential trouble spots but the service manual has a nice wiring diagram. What I did was print several of them and took highlighters following the wiring paths back to find potential trouble spots. After 3 nights, it turned out I had a bad ground connection in the large plug that connects the nose cone to the bike. Mine fired though and ran untill you let off the start button.

Good Luck

I concur, start by giving your fuses a once over if you haven't already since that the easiest thing to check and go from there. Mine wouldn't start one time bc the main ignition fuse was blown. Also, not sure if it's the same on the F4i by my F4 had the main ignition fuse buried inside a wire harness, not in the fuse block with the rest of them. Let us know how it turns out.

I haven't paid it much attention, being wintertime and everything. With the warm weather approaching , I decided to take it to the shop. They said it was a "crank sensor" and would be $150. I've never heard of a crank sensor, but it has something to do with sending spark to the plug or some shit. Anyways, its fixed and ready to roll.

glad to hear...hope they didn't screw ya...mine is dead too
I had a kinda bad accident that destroyed my right clipon, headlight assembly and upper....replaced the right clipon, but the fuel pump will not "engage" when i turn the key, thus no start...
I've asked here and on my groups site, but to no avail, as soon as I get a job, i'm gonna let honda gouge me for whatever they want....owchie....
