Hi All,

I've recently purchased a 2001 Fireblade, it was quite cheap so expected a few niggles.

On my first ride I got stranded in a pub in Somerset as the battery wasn't charging, replaced the reg/rec and Stator.

I had an auto electrician come and have a look at it as the reg/rec and stator had been wired together and just wanted to make sure that everything was ok.

Since doing so, when I start the bike, the injection system carries on priming, usually it just made a noise for a couple of second and then turns off. But it does start.

There was an odd wire attached to the -ve battery terminal, which I am assuming was for an datatool alarm which doesn't work (as well as some other dodgy bits going on).

Below are some photos from under the seat. Does anyone know why the system keeps on priming?

Sounds like a constant live feed to the pump, pop up the tank and have a look if any other wires are attached to the pump (besides the Harness)

Thanks for the reply spagiratwink. I've had a look under the tank and it doesn't seem like anything else is attached to the pump.

I've included a little video as it makes a different sound after 1 second.

I've never had this problem, and these are just educated GUESSES;
1. The Fuel Pump Relay is "going bad" and therefore malfunctioning and not stopped working. If there is an identical relay, try "swapping" them to see it the problem continues. If so, replace with new.

2. OR perhaps the FPR (fuel pressure regulator) is going bad? If the regulator isn't reading that the fuel system is fully "charged", maybe that's why it continues to prime?

again, just educated guesses. :twocents:

Good idea from @unslow1 ,swap that relay with the headlight relay to see if that works:wink

Just seen your picture, can you send us one looking from above and down :wink
That was a photo from earlier this week :|

Could they be on the outside of the tray? Sorry for all the questions, I am a bit of a noob when it comes to all of this.

On that first photo, there's a black wire with a fuse cap, looks like that goes to an alarm? the way some of those wires are spliced looks bad, im in my ofice at the moment, i can link you a wiring diagram, it helped me out a ton!

I think the black wire and fuse cap is a Battery Terminal Ring Connector Harness.

I am pretty sure the previous owner was Brian the Bodger... :frown

From what I can see, some or the alarm still looks attached, but it's all wrapped up.

See if it goes to the rear taillights. its probably spliced in to a white and grey wire that goes to your CDI/ECM.

Below is a link to a wiring diagram so you can compare and follow your lines. see what is added or spliced in and doesn't belong there. Good Luck
