HELP!!! Fuel Pump relay location!!!


motonap

Question

Hi team,

 

Had a funny thing happen to me this afternoon, took the bike out to the shop to get new tyres and when I tried to start the bike again, it wouldn't start. The bike cranks and keeps cranking but doesn't fire up.

At first I thought it was a air lock thing because it is a scorching hot day down south so opened and closed the fuel tank cover. Toggled the ignition switch on and off a couple of times but yet no avail.

Checked the battery and the voltage is 12.5V after considerable cranking.

 

I don't hear the fuel pump priming, so think it is possibly a fuel pump or fuel pump relay thing to check. Now I have looked at the service manual and it talks about a fuel pump relay but doesn't show the location of the relay on any of the illustrations, only other place it is mentioned is the wiring diagram.

Anyone know where one is supposed to look for this relay?

There are 3x relays that sit on the front left side of the bike (left side when you are sitting on the bike) behind the front fairing panel. But nothing specific to what any of those relays are for.

 

Just managed to get the bike towed home after a lot of delay on roadside assistance and dealing with the towing company, have hooked the battery up to the charger as well.

 

Anyone else had this issue where the bike just won't fire up? Any ideas as to what the possibilities are?

This bike does not have any relay behind the front fairing, youv seen the ABS pump and the voltage regulator there.

I belive what your looking for is the relay that sits on the right side of the bike (ground  side of the battery)  - but keep in mind there is almost 0 chance your relay is the problem. Check all of your fuses under the seat first.

I had a similar issue. I would turn the ignition on lights would come on. Hit the start button. Every thing goes off. My lithium battery is almost 2 years old I thought no way is it bad. Replaced battery. Bike runs perfect again. Same thing battery said 12.5 volts I thought that was enough. It’s not.

Update

 

turned out to be a immobilizer issue, for some reason the immobilizer deactivated itself and as a result the pump wouldn’t prime.

Took a while to figure that out and come to that conclusion, but the give away was the immobilizer light on the dash had stopped flashing. So not sure what bought that about, whether it was the key not being turned the right way or what.

finally put in the master key into the ignition, turned it on and off a couple of times and voila everything worked fine

.

its a pity I had to strip the bike, pull off the tank to check fuel pump connector settings, check the relays on the rear of the bike and all that jazz before I read about the immobilizer on one of the Facebook forums

So this issue came up again and I have found the only way to deal with it is to carry the master key with me. When I use the master key, the Immobilizer light glows on the dash and the bike starts up. After having done this, the spare key works great, no issues.

 

Lucky for me I had the master key on me when this happened the 2nd time, but not ideal to be carrying or using the master key as a backup plan, because you lose that key and you are stuffed!!

 

Yamaha dealer reckons they can replace it under warranty and thankfully the bike is still under warranty, but it does mean that I have to get it assessed by them, they put the warranty claim thru to Yamaha NZ and then once they accept it, the ignition barrel, tank lock barrel and seat release lock barrel will need to come in from Japan. So this could just end up being a long drawn wait and I just have to carry the master key with me until then.

 

It also means I have to ride 1hr to get to the dealer to assess the bike and then when the new set arrives they will take a whole day to replace all three. Really!! a whole day just because you need to remove the tank to do that 😮

Couldn't the shop help you in the parking lot?

This was a tyre shop, the only thing they could help with is a battery jump pack, which did not help.
