F4i problem HELP!
Re: F4i problem HELP!
look at the wires to the kill switch, they could be broken (if they were spliced maby they came apart). the fule pump relay check those take the ones off your good bike. fuses check those. the computer try a different one. ignition try a different one. if you spliced the tip over sencor wires check those. check the conections under the seat there is one that is spacificly for the fuel system chec the 20 watt fuse.if aftere all that is done and nothing happenes YOUR FUCCKED. no honestly its probly the relay

all that has been checked, and the relay has been changed

I did...
Re: F4i problem HELP!
do you have a multimeter? should be able to find the issue in a few steps.
1st, in the back of that relay there should be 2 grounds and 2 12volts (only 1 12volt when the kill is off) does the fuel relay "click" when you have the key on and turn the kill switch on and off?
2nd, make sure the two wires you spliced together for the tip sensor have 12v.
let me know how that goes.

I have changed the wiring harness twice and nothing. I have changed out the starter relay, cpu and still nothing.
Thanks

if you changed all the external parts of the wire harness, then the only thing that is on that bike (not in the harness,ecu,etc...) that will keep it from running is the Cam Position Sensor...... that is it. Look there.

no the starter doesn't turn.
the wire is still connected to the cam position sensor but I don't know if it's still good.
I have to borrow a multimeter mines broke.
Re: F4i problem HELP!
is your starter solenoid making a clicking sound or not(the bit your red battery lead goes to,you can hear this ticking like crazy when your battery hasnt enough juice to crank the starter but aint totally dead)these f*ck up or the sloenoid sticks.
f*ck the starter and cross the terminals on this solenoid with a screwdriver(insulated handle)this should bypass the ignition system with a nice blue spark effect and bike should fire up hopefully.
your bike got HISS ignition?

when the key is on, I get nothing at all. except lights and fan

the wire is still connected to the CPS but how do I know if it's bad?
Re: F4i problem HELP!
the relay should make a click.by crossing the terminals your finding out if the problem is between there and the switchgear or not.
has your battery got enough power!!!
regulator rectifiers are hondas weakpoint,im a bike mechanic and have found most honda electrical faults to be regulator failure,this will then destroy any battery you put in or not recharge it sufficiently (or at all)to crank starter motor.
i would also remove starter motor and connect directly to a seperate battery just to make sure it isnt seized.
check wire connectors going into back of fusebox to make sure none have come away.
cross those terminals,i use a big screwdriver as it tries to weld itself to the nuts when it arcs.

Re: F4i problem HELP!
I just cross jumped the starter relay and the motor turns over.
I'm thinking it's got to be a wiring problem, unless it has something to do with the Cam Position Sensor. or the wire going to it.

the cam sensor won't keep it from starting, only keep it from sending fuel and/or spark, starter will still turn. there are three interlock starting switches on this bike. safety switches
nuetral indicator
sidestand switch
clutch switch
if one is bad, which you said the nuetral was, then the other two will still allow it to start,(just have to pull the clutch even in nuetral) right now (i think) the ECM thinks the bike is in gear and the clutch is out, it wont start like that. double check those switches.

Re: F4i problem HELP!
clutch switch is at the clutch perch (two wires front underside), (bridge the two together and try to start) and inspect as far back as you can
sidestand is at the sidestand perch (underside), inspect wires back as far as you can
dont wory about the nutral its a ***** to get to and if you get the other two right you wont need it.
