Fuel pump not priming when trying to start...all lights and signals work but no sound from the fuel injection when clutch depressed to start engine...checked fuses at battery box 2 30 amp fuses ok...bike has only 4400 miles.....could fuel pump be out already?

you should start by the fuel injection pump. the engine may not be getting diesel or at least diesel under pressure, this is why is starts with 'quick start'. you should also check for leaks in the fuel hose (pressure side)if there is a priming pump, check for hissing sound there it could indicate a defective priming pump introducing air in the fuel system.
If your Celebrity is fuel injected or carbureted it will still have an electric fuel pump in the fuel tank. If fuel injected, open the breather and make the breather element wet with gasoline. If carbureted, pour a little gasoline into the venture of the carb then crank the engine. it will start. If it dies once the gas is used up, your fuel pump is not working. Could be a bad pump or a bad connection. check with a test light at the pump connection.
There is only a few cars fitted with an ancient petrol injection system that needed any priming.
Diesel engines mostly need the injection system priming but petrol injection systems do not.
Lots of cars use a system where the fuel pump runs for a couple of seconds when the ignition is switched on and that is all the time it takes to prime the fuel system. After a couple of seconds the fuel pump switches off and waits to restart when the engine is cranked.
As priming the system takes only a couple of seconds some manufacturers don't bother with the brief priming run of the pump and just have the pump start when cranking.
Could be faulty supply, fuse, pump relay or the pump itself.
If the car is fitted with an immobiliser, perhaps that is the problem.
check fuel filter first and that fuel pump works by openig at fuel pump and pushing fuel out just short of injection pump-- if no fuel pushes out prime fuel system by pushing air into fuel tank or using a in line hand fuel pump--- fill tank on tractor so that fuel is above injector pump also helps probably a prime problem
Is it electric or mechanical pump? Electric is with fuel injection. If its fuel injection, you should hear the pump run when you turn ignition switch. If u don't hear it, try starting, if no, turn off then on. It will self prime. Carburetor is with mechanical pump. I usually put few drops of gas in the carb. Start it, if no, more in carb till it stays running.
If you're referring to a fuel injected gasoline vehicle, self prime takes place at key start. If you still feel the need to have the computer repeat this process (or re- self prime), turn the key all the way until the dash lights come on, then turn off. Repeat this 5 times then attempt to start. If all the windows are closed and the radio is off, when you turn key on with engine off, you'll hear the fuel pump at the rear of vehicle buzz or hum as it's priming the system.
Your fuel pump is in the tank. Turn on the ignition, and listen if you can hear the pump run in the tank. It will only run a few seconds if the engine is not running. You can repeat this several times to prime the fuel injection.
There is a check valve in the fuel pump that sounds like it may have gone bad. Check the fuel pressure at the shredder valve, there should be 60 to 65psi during the prime and will drop 5 psi when the engine is running. Once the fuel line is primed, check to see how fast you lose your prime. Since you replaced your injection system, we can eliminate the fuel pressure regulator leaking which was common on the injection system your truck run's on. If the fuel pressure drops fast then it's going to be a bad check valve at the fuel pump and it may be time to replace the fuel pump it self. Good luck and hope this helps. Note: do not try to start the engine with putting gas through the throttle body, it's been know for small fires to start and burn the spider injectors.
Sounds like air in the fuel line. Try turning the key ON and pumping the gas pedal (it may take 10-15 times) and then try to start the car. You need to force gas through the fuel lines to dispel the air it was pumping when the car ran out of gas. If it doesn't work the first time, let it rest and repeat by pumping the gas. Best of luck!
