SOURCE: it cranks but no fuel in the glass filter does

I'm 90% sure they do. Disconect the fuel line at the carbys(ignition off). put the end of the fuel line over a container. Switch on the ignition. Fuel should now be delivered. If not you could have a fuel pump issue or a blockage somwhere between the fuel tap and the carbies. Follow the fuel lines from the fuel tank.
Also if it does have a fuel pump as I think it does you should hear it run (a buzz) when you turn the ignition on. Hope this helps Andrew Porrelli

SOURCE: is it Possible Tha Carburator Dirty Could cause The bike no Star

Yes, a dirty Carburetor can stop the engine from running.

Drain the carburetors. There should be a screw on the lower side of each CARB float bowl. Remove the screw then replace it after the fuel drains. Is there any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Turn the gas back on and wait a minute for the carbs to fill with gas. Try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.

FOR EACH CARB > Remove the float bowl and clean the entire
Carb with a spray Carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the Carb.

FOR NO SPARK > Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? Is the kill switch on? Does the side stand have a kill switch? Is it working properly? Tip-over kill switch on your bike? Check the operation of the ignition switch and all kill switches with a volt ohmmeter.

Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.

SOURCE: 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.

Regards
Phillip

Fuel pump not activating when trying to start engine


just to elaborate a bit to the previous answer (and I know this might seem a bit redundant)...check the fuse!

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.

Fuel pump fuse blow when I turn the ignition on and cranks but no start, why?


Unplug the connector at the fuel pump. Install a new fuel pump fuse. Try to start the car. Does the fuse blow? If not that the problem is probably a bad fuel pump. If the fuse does blow with the pump disconnected than you need to look for a short in the power supply to the fuel pump.

1994 Goldwing GL1500 won't start. It cranks, battery is good. Check fuel pump, but no fuel is flowing. Is there a fuel shut-off switch?


Not pumping fuel. There is either a blown fuse, a bad relay empty gas tank, bad electrical connection, bad ground or a bad fuel pump. For a bad electrical connect, take apart any connection related to the problem and if bad, remove connector and hard wire it.

Started car 3 weeks ago just fine tried to start yesterday turns over just fine but tried to listen for fuel pump cant hear it come on maybe fuse i need to check first but dont know which one or maybe add...


First of all, a little "auto repair 101" is in order... It is absolutely impossible for the fuse to be the problem. If the fuse is blown, there is a reason for it. Fuses are NEVER the CAUSE of an electrical circuit problem. Blown fuses are ALWAYS the RESULT of an electrical circuit problem. Simply replacing a blown fuse without finding and correcting the reason that it blew in the first place, will not fix your car.
.
.
Now that we have that part done with, I would say that if you cannot hear the pump running. the pump is most likely the cause of your "Cranks, Won't Start" problem. Keep in mind that the pump will only run for about 2 seconds when you turn the key to the "ON" position. I recommend using 2 people and removing your gas cap and place your ear near the fuel fill tube to listen while someone else turns the key on. If the pump is not running, sometimes you can get it to run if you have someone turn the key on while you hit the bottom of the fuel tank with your fist.(Hit with your fist as hard as you can) A rubber mallot also works good for this. I don't recommend using any metal objects for this purpose, because the can spark. (Sparks and fuel tanks do not mix well :) )

Fuel pump replacement


How to Replace a Fuel Pump

Parts:
1. Fuel Pump - $51.16

ff89027.jpg

DELPHI, ELECTRIC FUEL PUMP -- Meets Or Exceeds OEM Quality, Matches The Genuine Fit And Function

Tools:
1. 3/8 in. Drive Ratchet
2. Floor Jack
3. Multimeter
4. Jack Stand Set
5. Flat Head Screwdriver
6. Mallet Hammer
7. Socket Set

Steps:
Step 1 * Locate the fuel pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 * Have a friend turn the key to the“ON” position while you listen for a high pitched hiss/whine coming from the electric fuel pump.
o Tip: If the fuel pump is located in the fuel tank, you can open the fuel cap and listen to hear the fuel pump. The fuel pump should run (priming the system with fuel) for a couple of seconds. Once it stops, you should be able to start the vehicle.

Step 3 * If the fuel pump does not make a sound (run and prime the fuel system) check to see if there is a fuse that supplies power to the fuel pump and check its location.
o Tip: Check the owner’s manual for location of the fuse box and fuel pump fuse.

Step 4 * Once you have found the location of the fuel pump fuse, remove the fuse from its housing and check to see if it is blown.
o Tip: A blown fuse will usually have a metal strip connecting both tabs that“blows out” (the wire looks as if it has been chopped in half or broken).

Step 5 * If you noticed that the fuse was blown, replace the fuse with a new fuse of the same amperage and repeat step 2.

Step 6 * If the fuel pump now works, you do not need to replace it. However, you will need to find what caused the fuel pump fuse to blow. We strongly recommend that this is done through a certified shop, unless you have the tools and knowledge to test electrical systems and diagnose more in depth problems.

Step 7 * If the fuse wasn’t blown, it should be checked for power and ground at the fuel pump. If there is power and ground present then you will need to replace the fuel pump.
o Tip: On most vehicles you may need to lower the fuel tank to access the power and ground leads for the fuel pump.

Step 8 * Siphon or drain as much fuel as possible from the fuel tank. Disconnect any possible fuel lines from the fuel tank.

Step 9 * Remove any retaining straps or bolts holding the fuel tank to the frame.
o Tip: You may be able to access the fuel pump from the bottom of the back seat or the trunk of the vehicle.

Step 10 * Using a digital multi meter, turn the key to the“ON” position and check for power at the fuel pump. Touch the negative lead from the DMM to a good ground and the positive lead of the DMM to the power cable at the fuel pump. You should have a reading that is equal to battery power. If you do not have a reading at all, you will need to inspect the power side of the fuel pump.
o Tip: With the ground lead of the DMM still connected to a good ground, touch the power lead to the positive side of the battery, to each side of the fuse, and again to the fuel pump. Wherever you notice the voltage reading goes from battery voltage to 0 you will need to replace whatever wires and fuse are in between.

Step 11 * If you have noticed that the power and ground being supplied to the fuel pump are both good, then you will need to replace the fuel pump.
o Tip: To check for a good ground, place the negative lead from the DMM to the ground side of the fuel pump, and the positive lead of the DMM to the positive side of the battery. If the reading on the DMM is battery voltage then you have a good ground.

Step 12 * Remove any retaining rings or bolts that hold the fuel pump in the fuel tank.

Step 13 * Remove any electrical connections or fuel lines connected to the fuel pump. Replace the fuel pump.
o Tip: If equipped, inspect and replace strainer as needed.

Step 14 * Use reverse procedure to install fuel pump and assemble all components back to their original state.

Step 15 * Start the vehicle to verify repairs.


Good job (remember rated and comment this help).
