From my personal experience I can tell you that more often then not fuel pumps fail internally and very sudden. Test the voltage coming from the two wires that are usually in a harness and clip assembly. turn your tester to dc volts setting and stick ends of probe of mulimeter into each respective hole and then attempt to START. this is only to test for starting voltage so it will not need to be starting for long as it only takes a second or two to allow you to read the voltage. If it has twelve volts or six whichever setup you have and you cannot hear any noise then try to tap it and free the solenoid to disengage it and buy you enough time to get a new fuel pump please send me a reply as to what happened and ill give you a call if you need help

Fuel problem


Hi Bill

Check the fuel pump wiring for power, if there is power going to the pump, I'd say the fuel pump malfunctioned and has to be removed from the fuel tank.

I hope this helps.

Injectors not shooting gas in thottle bodies


There could be many reasons for this, some simple, some not so simple, so you will need to start by eliminating simple things first.

The first thing to check is the battery. Is it fully charged and in good enough shape to supply the electrical load needed to make the bike run correctly (bikes with electronic ignition and fuel injection must have a good battery for the bike to run properly)?

Next, take a look at your owners manual and find out if there is a fuse for the fuel injection system. If there is, is it good?

When you insert the key and turn the ignition on can you hear the fuel pump? If not, you fuel pump is either dead or not getting power for one reason or another.

Many cars are equiped with a safety switch which automaticly turns off the fuel pump in the event of an accident. These can be reset by simply pushing a button. Is your bike equipped with something similar?

When was the last time the bike was running? The gas sold today is notorious for not being stable for very long. If everything else on the bike checks out ok, there is a remote chance your injectors are clogged with bad fuel.

My 99 cbr 600 ran out of gas how do i prime the pump?


Turn the bike off with the kill switch. Turn the key and listen for the pump to prime.
If it doesn't.
Check all fuses.
Check your fuel pump relay fuse - try taking it out and putting it back in.
Check you main fuse next to the battery (30A).
If you replaced any fairings or did any modifications to the bike, make sure you didn't mess up the BAS\Roll over sensor as the bike may think its on its side and will not pump fuel.
Check all wires in the wiring harness make sure there is no corrosion and the fuel pump relay is getting power.

Fuel pump not priming


if bike has been sitting the pump may be locked up, also check the fuse for the fuel pump or the igntition to make sure it is good. check the voltage on the wires going to the fuel pump panel if you have power there for 5 seconds when you turn on key the pump is mosy likely the problem. Brian

Yamaha Virago 535 Fuel Pump Dead


My first question: is it ok to run the bike using only gravity fed fuel if I'm ok with a top end of only 60 mph, or am I damaging something else on the bike by doing that?
To answer your it, you fuel pumps still works and you are not doing anymore harm than possible.

**My second question: is there a way around buying the $300+ fuel pump in order to get the bike running properly again?
YES, go to a bike dismantler/wrecker who does the same tipe of bike

***My third question: WHY DOES THE FUEL PUMP COST
$300+!!?!?!??!
Well, can not answer that because I don't know....

Good enough?

I was wondering if there was a fuse for the fuel pump, or if there has to be a certain amount of fuel in the tank for pump to kick on?


most all bikes i"ve worked on have fuse protection. i"ve been on this site for awhile and have seen many questions about fuel pumps, but so far nobody has ever included in their diagnoses that there bike starts and runs fine. but i myself can see why.. because i ran into the same problem with my old cbr..it just wasnt running fine, seemed like a fuel issue so i turned the key on and tried to listen for a pump sound and found none, so i purchased a new pump, and installed it and turned the key and was so happy to hear the pump sound, fixed right! no, i turned it off and tried it again and then no sound, and in my mind im saying oh no! i just burnt up a new pump, but i said i"ll find out for sure so i took the old pump and reinstalled it (minus all the fuel that was left in it when i dumped it out)... and i turned the key on and voila! i heard the noise and now knew that i wasted $75 bucks! But, oh well, i got a spare now..i talked to another mechanic friend of mine about this problem and he been working on bike for over 40 years and he said you'll know if you have a fuel pump problem if you start to loose power in the upper rpm ranges... it"ll demand more fuel then its getting..so when the fuel pressure is correct i'm guessing that the fuel pump doesnt need the prime on all the time. but just to appease myself, i took the fuel pump hose off the fuel filter that was from the pump and ran it to a gas can and i started the bike and saw and felt the fuel squirtting out of the pump...but then i still had to correct the hesitation problem, so i heard about this Sea Foam cleaner stuff that can be purchased from Autozone $10 a can, pour in 1/3 can to 2 gallons fuel..bike was hard to start but would always push start.. so i got it started and ran it for about 11 miles before the stuff had eatin away at whatever was clogging up my carbs and it worked ever since then..so you might want to give this a try.
can you rate my answer, thanks!

When I try to start my bike, it appears that the engine is not being primed. Cannot here the pump running.


This could be a number of things - the power is interlocked by the neutral switch/side stand relay - bike must be in neutral OR the sidestand must be up in order to get power to the fuel pump relay.

Things to check:
Fuses for ignition and fuel pump
sidestand up &/or bike in neutral (neutral light displayed)
kill/run switch in 'run'
sidestand relay
fuel pump relay
Tip Over Switch
