was riding today and put the bike down,,, and it shut off,,,,
has no tip over
cranks no fuel pump
no power to the fuel pump
checking the ign switch
help i want to go beat my bike to day but cant,,, wont run

sounds like a grounded wire. check fuses 30amp, 10amp, check wiring coming right off of 30amp, check for fraying...check batt

JOHN J

john check your terminals on your battery and make sure they are tighten down, **** happened to me like 2 weeks ago, my ground was loose and bike wouldnt sart. give me holla hope this helps.

Johnf

well i checked all that crap

the bat was low but not yesterday when the problem started,,,, i was stupid and left the ignition on all night,,,,,,,the fule pump still will not kick on,,,, and is not reciving power,,, the rest of the ignition is,,,
what are the two relays on the sub frame for,,, only one is kicking on and the other is not,,,,,,,,,

Johnf

just jumped the fuel pump,,,,, works good,,
checked the emergence kill switch,, i cycles the relay on the tail,,, but the other relay still does nothing,,,,, should i just try a new harness,,,, the injectors have power, to them,,, i know if there not all put in a serease they will not work,,,
iv checked for frays in the wire with no luck,, did find where the previous owner
hacked the tip sensor off the bike,,,

xxMICKEYxx

Mine did that **** last night and it was a bad connection at the upper harness connector(big grey one). The other relay u were referring to is a turn signal relay.

xxMICKEYxx

Now mine is cutting out everytime I clutch it up past bp Its acting like its running out of gas or something but it has a full tank. Gotta go tear this hunk of **** apart again and see what I find.

Johnf

does ant body have a pic of the fuse top,,, a fuse was poped when it started,,, this might help

______

Well?? did that work

Johnf

no i need a pic of the top of the box so i can read what fuze poped,,,,,,,

Johnf

thanks didnot check that,, ill hit it up when i get home from work

the two relays on the subframe are for engine cut off and fuel pump relay. I believe the manual states how to diagnose them both. If you dont have it i can find it. To me it still sounds like a grounding issue. keep us posted...

Johnf

ok,,, i need to know how to test them,,, but i dont think thats it,, i switched the relays and still the same one clicked... i removed the grounds and cleaned the frame and the brass,,,,, i checked the injectors,, if there not all conneted the fuel pump wont kick on,,,,,,, man this is messing with me,,, my 929rr did this and i ended up selling it

287ridah

basically im in the same boat. The manual states to test the connection to the fuel pump then 30 amp 10amp , then relays. After that they point to the ECU. My relay clicks only when I turn the bike to off though. when does yours click. I wont have time till later to check the manual again though. As i said my bike is doing the same **** so well rigure it out..side note check all wiring coming out of the ecu. I've had problems in the past were the wiring right there can break or come out of the ecu and cause problems...something to check.

Johnf

checked that,,,,,,, will look closer,,,,,,,, and the main harness wass almose disconnected,,,, put that tight,, nothing,,,,, will look at the computer,, there is no spark from the plugs,,, i would say bank/lean angle sensor but i dont have one,,,, so this is starting to point to the computer or connetions

-SKETCHY-

Check the bottom of the fuse box where the TOS wires run. My F4I did this and it turned out that the wire had become slightly dislodged from the fuse box. Took forever to find it too.

Johnf

well i pined all the connections,, got contaneuity,,, and the tip over sensor has power,,,,,,, i might be wrong but the tip over sensor just needs to be removed,,, i didnt di it but i just have wires and there insulated from each other ,,,, what are the clutch wires colored as,, i cant remember if i needed to have the wires hooked up for it to start out of gear,,,,,

i was blowin main fuses like skittles a few weeks back....

i had a pink wire fray out the black side of the ecu, also my ground was all freyed at the main fuse box....

a ton of soldier and a new harness fixed this for me....

If anyone wants it I have the manual for the f4i's in a pdf, its just to big for email or this (i tried twice to post it)

Random question, took my f4i apart today, its my second, and there are stickers that say F42 all over the bike. The actual sticker says CBR600F42, anyone seen these before because even on my other f4i everything said f4i?

I checked the fuel pump connector at the harness.
ignition switch to "ON" measure voltage between terminals.
Connection. Brown (+) - Green (-)
There should be batt voltage for a few sec.
IF there is batt voltage, replace fuel pump.
IF there is no batt volt. inspect the following:
-Main fuse 30A (check)
-Sub fuse 10A (check)
-Engine stop switch:U can check continuity between Ignition and BATT when switch is on.
-Fuel Cutoff relay: Connect a ohmmeter to the connection terminal. (black/white - brown) then 12v to (brown/black - black/white) S/B continuity when 12v is connected.
-Engine stop relay: Connect a ohmmeter checking connection Red/white - black. The other side connect to 12V (Red/white - black. S/B continuity when 12v is connected.
-bank angle sensor: S/B disconnected. check.
-ECM: theres a special tool they use to check wiring harness and ECM. ONce your here its either spend time hunting for the short in your harness or get a new harness/ECM.


These are things to check when you know you have spark but no fuel.
I know F4i's have issues with wiring harnesses fraying near the ECM also....
