Electronic Fuel Pump

Have stored my motorcycle over winter went to start it but no electronic pump sound when turning the ignition on. Engine turned over fine on electric start but would not fire up. Checked plug was very dry so no fuel getting to injectors. It sounds like fuel pump not working or could it be the relay. If so where is the relay and if i need to change fuel pump i undrestand it is in fuel tank. Could the relay be sticking due to storage.
Thanks Paul.

It turned out that the ignition key was faulty and it cut out my fuel pump and power to my spark plug but all other electrics worked. Tried my spare key and could hear fuel pump working pressed starter and it fired up how bizarre is that. so problem sorted.

My fuel pump is not running on my FXDB

Pull any error codes:

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button.
Background lighting sould illuminate, speedometer needle should sweep
its full range
and indicator lamps (battery, security, low fuel, check engine and
cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection
menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The
module that is flashing is the one you are going to check. To move
from one letter (module)
to the next, you push the odometer reset button one time. (from P to S
to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module (EFI) / (Ignition Control
Module, 'Carbureted')
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the
odometer reset button in for 5 seconds and release. If there are any
DTC's the code will be
displayed or the word "none" will appear if there are no DTC's. Push
the odometer reset button again to view additional codes if they
7 - Record the codes.

Once you have any error codes, repost them.

A few examples of what some codes are:


These do not necessarily, are the codes you'll get, but rather just an example of what the format the codes are displayed as.

Hi, Check the solenoid on or near the starter. This is the first thing that comes to my mind. Second is the ignition module. (electronic box) Which controlls spark to the engine. Check those out. Good luck.

Backfires and won't start. when ignition is on the fuelpump makes a funny sound.

The fuel pump should engange when ignition is turned on, but then stop after a couple of seconds. This sounds like there is a fault in the fuel system, since the pump does not stop? Maybe a leak somewhere, or some defective valve. I would take it to a decent shop to have it checked, there might be fault codes they can read from the bikes electronic control system.

My honda cbr 600 is struggling as if it keeps running out of petrol. whats happening??

it sounds like it's being starved of fuel, has it been stored for winter? check fuel filter or just change it now, if stored over winter could be carbs gummed up. get some Berrymans B12 fuel additive and double dosage, run til hot then let it stand overnight. pray hard and hopfully it will all be good.
do you have a electronic fuel pump? does it run constantly? if so its not getting enough to feed the carbs. could be as i said the filter or if you have bad luck it could be the pump.

EFI pump

Anyone with a Sprint, Daytona or S3 will tell you that this is normal. When you turn the key, the fuel system primes and the ECU does a self check for a second or 3. Wait for the self check to finish before trying to start the bike (so much for a fast getaway) On my RS, in the cold weather, the fuel pump is much louder than normal for a while, but once up to temperature, it goes away. Welcome to the electronic age.
