cbr1kfireblade · 08-16-2009, 6:28 PM

what happens just when you turn the key on? lights sounds etc?

CadilacWill · 08-16-2009, 7:22 PM

I have the same problem, if anyone knows I would really appreciate some help

it turns over, but just won't catch the fuel pump is good, the spark plugs are good, the ignition is good, and the ecm must be relatively good because it does do everything but start.

From what I have deduced there is no spark, and the pump does not prime I really am at a loss here so any help would be apreciated

cadilac did you find out what was wrong

CadilacWill · 08-17-2009, 7:36 PM

My latest assumption is the Fuel Cut Off Relay, but I have yet to test it
I'll let you know my results

CadilacWill · 08-17-2009, 10:16 PM

I jumped the black/white wire to the solid brown wire which made the pump prime and everything

so now I have to find out why I am not getting spark and then my baby will run

If anyone can help me find out why I am not gettin spark I would really appreciate it

It is not a starter relay it is a fuel cut off relay which is on the way back on the right side. It is under the farthest back fairing

alright i see two relays wich one is it should i buy a new one??

CadilacWill · 08-18-2009, 1:13 AM

Here is the process I tried
1. So, locate the Fuel Cut off Relay. It should be on the right side of the rear frame above the rear passenger foot peg.
2. The relay you need is the one furthest back.
3. Disconnect the plug from the bottom of the relay.
4. Insert a jumper wire from the Brown Wire to the Black/White Wire.
5. With the jumper in place, turn the key to the "ON" position for 10 seconds.
6. After 10 Seconds, turn the key "OFF"
7. Remove the jumper wire and re-connect the plug into the relay.
8. Make sure the bank angle sensor is vertical and upright.
9. Turn the key to the "ON" position and flip the Run/Stop Switch to the Run position. You should now hear the fuel pump prime and the bike will now start.

My bike did not start because it did not give me spark, but made my fuel pump prime
I would give it a go

YO CADILAC WHATS YOUR EMAIL OR NUMBER SO I CAN GIVE YU A CALL WHILE IM DOING THIS CUZ I CANT GET IT 2 WORK MAN IS THERE SUMTHING I MIGHT B DOING WITCH ONE OF THE 2 BLACK WIRES

Billygoat · 08-18-2009, 10:05 PM

Hey Guys
had simular things happen to my bike.
Except mine let some fuel by even if the pump was not working.
If you can't jump the pump with 12V, take the electrical side of the pump off and clean the contact points with a file. Be careful!! not to damage the it while filing/sanding
I did this to my pump cuz the contacts got dirty from arcing. I also used a bigger fuel cut relay, cuz honda wanted 70 for it. I think the pump contacts arced, drawing more juice to the relay.
Anyway, you can check to see if the relay is working by using the three wires.
At fuel cut off relay there is a plug.
Don't know which order they are, but 1 is return to pump. 2. 12V trigger(low amp) 3. 12V (high amp) which powers the pump.
Hope this helps.

CadilacWill · 08-19-2009, 12:57 AM

the two wires closests to the front on the farthest back relay

that is what worked for me

R Dub · 08-20-2009, 10:19 PM

Hey guys. Sounds like you were having the same problem that I was having. It turned out to be the headlight harness. The green wire (ground) had a bad connection. Follow your head light harness to the left of the bike where it plugs into the main harness(its a gray connector) and make sure that green wire is not corroded out and is tight. I hear that's a very common issue on these bikes. It you need pics let me know and I will be happy to send you a link.

asantos · 08-20-2009, 10:28 PM

yea send me those picsz i wanna do that rite now

asantos · 08-20-2009, 10:52 PM

this s*** is pissin me off all i wanna do is kick it over

R Dub · 08-21-2009, 12:36 AM

you said when you jump the fuel cut relay you hear it prime....will it start then?

asantos · 08-21-2009, 12:58 AM

nope i jump it with a wire nd turnthe key to on with the kill switch to the run position the fuel pump just stays priming so i kno the switch is good nd so is the pump just dnt kno wtf it is i ordered a fuel cut off relay so lets see

yoo yu gotta aim or suttin

R Dub · 08-21-2009, 10:30 AM

Yeah man I got AIM. My screename is Rwdirtbike.

But you said when you flip the kill switch you can hear a click which I would imagine would be the fuel cut relay and that means that it is good. I am not trying to rule that out as the problem but I have seen a lot of people think that was wrong, spend the money on a new one and then that doesn't fix it.

You said the bike ran fine before the battery went dead right? I know you probably tried this 100 times but put the battery on a charger and let it sit there for a while. These bikes need a full battery to run. One time my bike would turn over fine and seemed like it should start but wouldn't. Put the charger on it and it fired right up.

Another thing to double or triple check is the kick stand switch. Make sure the bike is in neutral. We have all forgot that once or twice. You might want to bypass that switch to see what happens.

When you turn the key on what lights come on on your cluster?

asantos · 08-21-2009, 1:42 PM

im just gonna take a video nd post it 2 show yu wat happensz

asantos · 08-21-2009, 8:42 PM

UPDATE: got a new fuel cut off relay bike still doesnt start when i use a jumper wire the pump will prime wen i put the relay nothing at all i feel like burning this f***** bike

R Dub · 08-21-2009, 9:24 PM

Sorry man that sucks. I thought it might not fix it though. The relays are not known for going out. Snap a pic of your cluster when the key is on and post it.

asantos · 08-25-2009, 1:41 AM

UPDATE BIKE IS FIXED THANKSZ EVERYONE MY BIKE WAS PREVIOUSLY REWIRED BY A STEALERSHIPND LIKE ALWAYSZ IT WAS HALFASSED SO WEN I REMOVE THE ECU TO CHANGE THE BATTERY A CABLE FOIR THE ECU THAT WAS ONLY CONNECTED BY TAPE FELL OF I NEVER NOTICED TILL MY 7 YEAR OLD BROTHER CAME IN TO THE GARAGE ND SAID WATSZS THAT CABLE DOING OUT SO IT WAS DUMB OF ME NOT TO SEE THAT SO NOW IM HAPPY GOT MY BIKE BACK ND MY BROTHER IS HAPPY HE GOT MCDONALDSZ AND A POCKET BIKE

i'm having this problem on my 2002 F4i also. checked all the fuses, and headlights work. I am getting spark, and tested both the engine cutoff relay and the fuel cut off relay relays and they both click when i gave them voltage. the fuel pump does not prime, but I connected the pump directly to the battery and it worked. When i turn the kill switch on I dont hear any click from the relay. I also bypassed the tip-over sensor and that didn't help so i'm assuming thats fine too. so then I followed these steps CadilacWill posted

1. So, locate the Fuel Cut off Relay. It should be on the right side of the rear frame above the rear passenger foot peg.
2. The relay you need is the one furthest back.
3. Disconnect the plug from the bottom of the relay.
4. Insert a jumper wire from the Brown Wire to the Black/White Wire.
5. With the jumper in place, turn the key to the "ON" position for 10 seconds.
6. After 10 Seconds, turn the key "OFF"
7. Remove the jumper wire and re-connect the plug into the relay.
8. Make sure the bank angle sensor is vertical and upright.
9. Turn the key to the "ON" position and flip the Run/Stop Switch to the Run position. You should now hear the fuel pump prime and the bike will now start.

When I put the shorted wire on, the fuel pump started going so I started the bike and it ran fine. Unfortunately after i put the relay back I was back to square one with it not starting again

thanks for any help
