Fuel pump won't prime!!!
 
Been working on it for months now 2002 cbr 954rr I put a new motor and wiring harness in bike cranks all day seems the pump is getting power and pink wire on ignition is good but fuel pump relay won't click and only wire giving power to the ecu is the pink one from the ignition I can't get my finger around and I have to fix this bike is one I've always wanted

https://cbrforum.com/forum/cbr-954rr...r954rr-164130/

I’ve helped over 100 people with this exact problem fix their no-start bike in remote parking lots in middle of night via phone!

Least you can do is post some numbers from following guide. You’ve been at this for months now and have not posted single number! NO ONE can help you unless we know what’s wrong with your machine. Only way to figure that out is by looking at numbers you measure. Help us help you!

Let’s start with basic measurements:

0. measure battery voltage, volts = ???

1. measure red wire going into ignition switch, volts = ??

2a. measure red/blk wire leaving ign-switch, volts = ??
2b. measure red/blk wire going into fusebox, volts = ??

… etc…

We can assume that battery has power since it can crank starter. And we know pump is not getting power because it’s not priming. So all we have tomdo is follow path of electricity between battery to pump and see where it stops, simple right? Basic measurement: 13v -> 13v -> 13v -> 13v -> 0v <- aHAH!! There’s your problem!!! Less than 5-minute repair! But you have to do the measurement steps and be our hands and eyes, we’re not there!

The sooner you do these tests, the sooner you’ll get bike running. Heck, pay overnight hotel stay and round-trip ticket for me and I’ll fix it for you in 5-minutes… Or less in many cases..

here's the thing I'm not good with all the wiring idk what to test or what to send

I'm not sure if there's some sort of processing disorder or dyslexia or extreme ADHD, but here's why you're NEVER gonna be able to fix this bike.

1. What's very 1st measurement step listed in guide???

0. measure battery voltage, volts = ???
2. What's very 1st thing you post?

Fuel pump plug in
Find anywhere in entire troubleshooting guide that says to measure "Fuel pump plug in"???

I'm really done with this bike, complete waste of time for everyone.

I battery was 11 as well same with Fuze box wire and ignition all of it was 11 yes I have adhd but I've worked on planty of bikes there is no need for u to act like this I just am confused
1:battery voltage is 11
2: fuse box voltage is 11
​​​​​3: ignition blk and red wire is 11 same as for red wire 11
4: FUZE BOX IS 11

Charge the battery - you're looking fire a battery voltage of 12.8 at the very minimum.

kratos954cc Feb 14, 2024 09:20 PM

We had its up to 13v it was on a jumper but I'm just confused on how the ecu plugs have no power except the pink wire
