2006 Honda CBF 600 fuel pump not priming

Bike lights up and headlights work, engine cranks with a new battery. fuel relay doesn't even turn on when I flip the kill switch on. seems to be a problem with the fuel pump not turning and pumping fuel. The bike has been in the shop for a month at a Honda power sports dealership. I drove it to them and they watched me drive in with no problems.. they attempted some cosmetics work on it and it won't start now...... they even put a new battery in. kinda crazy eh!!!!!

Hi, Anonymous the following is a systematic procedure for diagnosing fuel pump issues designed to keep "DRACHMA" to a minimum. If you need parts check with Amazon and eBay first to keep costs down.
1. If your pump does not turn on check the pump fuse and relay and all wiring including connectors for corroded, broken, or loose pins/sockets.
1. Normal fuel pump pressure is 3-5 PSI.
2. Check any rubber or plastic tubing for age-related pinholes by removing and plugging the ends that connect to the fuel valve and then turn on the ignition switch and watch for fuel streams exiting the pinholes, if any exist, replace tubing as necessary.
3. Check for a clogged a primary fuel filter that comes off the bottom of the pump to screen out big rocks and clean as necessary.
4. Check for a clogged secondary fuel filter that's outside if applicable by removing it from the system and replace it with a short splicing tube turn on the ignition switch and recheck fuel pressure if pressure increases to normal pressure you need a new secondary filter.
5. If all the above check out OK and the pump is not functioning properly then you need a new fuel pump.

I don't think you have a short. It sounds like the earth cable is broken somewhere and is arcing when you start drawing a bit of current.

SOURCE: honda motorcycle fuel pump not working

check your key it has a chip in side it and it may be faulty try your spear and i know it sounds silly but just make sure your kill switch is set to run check the hiss fuse under the seat also swap your fuel pump relay with the fan one the fuel pump relay has brown wires going to it and the fan has black and blue if you have an alarm on it it will be worth checking that make sure that the fuel pump is pluged in under the tank take a look at the hiss light does it go out wen the bike is switched on if it stays on you have a HISS problem any problems let me know and i will do my best to help

SOURCE: honda cbr954rr electrical problem

see if you can find the fuel cutoff relay and jumper the connector with 12volts, you should be able to jumper across two wires, using a paper clip or something like that. Make sure key is off first ...now turn on the key and you should here it. The tail light could just be a separate issue, did you check your fuses.. maybe the bulb is burnt out. See if the bike will push start..if it does, then drive it and get up to speed if the fuel pump is not doing its job you wont be able to hold that speed for long..it might even start bogging down.

I turn my key to my 98 gsxr 750 fuel injected bike and the only thing that comes on are the lights and horn. no noise what so ever. Bike wont crank unless a charger is put directly up to the starter and...


Is your "kill switch" on or off?

1998, is your battery new and up to snuff? Do a hydro test on it ... 1200 is a good reading, A volt test should show at least 11 Volts DC. If this is all ok ... You might want to check the start relay. Check these things, if they are ok, send me a 'comment' to this question and we will go int the testing for the start relay.

Deal?

Motorbike yamaha will not start


Didn't say much about what it does or doesn't do as trying to start. The batrtey all the way up? if not it can refuse to start even if cranking 2002 and newer may push start but only if the battery is near good 04 and newer are fuel injection and a low or bad battery is a no start on it's own the modern glass mat batteries don't take a jump very well as they resist being pushed back to full voltage even with a car battery. Cranks good with a good battery. Got gas and the valve on? Carb bikes may have to have the fuel pet on prime to start a (dry) motor. The fuel injection bikes have to have the good battery or the fuel pump can be below theasehold and the relay won't turn the pump on. All the lights and others horn ect working? No crank can be clutch switch kickstand switch if the locic box is burnt out or low voltage, Neutral light working? if not the kickstand has to be up for crank. Burn the strarter out cranking with low battery? Strong click when pushing the start button says the safty switches are working. and the starter could be bad or lost it's ground. Will the engin turn? put the bike in higher gear and push it with the clutch out to see if it will turn good compression may be hard to push but not impossible as the starter and you have about the same power, remember they used to have kickers and this one had one it'd work to start it. Carb bikes have drain bolts on the float bowels and little hses hooked to them if their still there open the screws to see that theres gas or something else in the corbs. and will more come from the tank? Spark the plug wires snap to the plugs and are hard to remove if good put a plug ( any good plug will do) and crank the engine to see the spark at the wire. if not kill switches crash swiches may have to be reset then the key on and off too. lfter that its lookto see whats missing as compression spark and fuel are all it needs to run. If it jumped time the compression won't be good or out rajous. Exhaust stopped up? I've seena mouse store corn in the exhaust and forget wher he packed it. seen a R6 completly full! no start air cleaner housings get filled the same way. these don't apply if the bike had been running recently. Bad or poor battery most likly cause of no start then cable connections

Yamaha trx850 bike stopped then restarted no problem following week stopped again this time would not restart--no spark at all been in bike shop for 2 weeks they cant find anything wrong


If they find nothing wrong then the problem is obviously intermittent and can be very hard to find. 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 wire connection.

The usual source of intermittent loss of spark is the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode controller integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.The dealer would / should have load tested the various ignition components. I will assume the ignition system is okay. Check the battery and fuses. Install a new set of stock spark plugs.

No spark 110cc engine wont start


Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? If needed, add water to the battery cells enough to cover the top of the cell plates.Try a jump start from your car battery. Is the kill switch on? Check the operation of the ignition switch with a volt ohmmeter. You should be getting power into and out of the ignition switch.

If the bike doesn't start and run properly check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Broken or out of adjustment, it would kill the spark. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.

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.

Bike in neutral will not start


could be kickstand switch or neutral switch. also check kill switch. starter relay should be under seat by main electrical harness with rest of bike relays.

Won't start


If the engine will not even crank have the battery load tested, if the battery is fine it could be the ignition switch or the starter button. Also make sure all of your grounds are tight and clean.

Starting my bike


Hi,

On most bikes including Kawasakis, the starter button would be on the right side of the handle bar on the throttle grip assembly. It would be right below the headlight switch. Above the headlight switch would be a switch that must be set to RUN, this is the engine kill switch.

If the above still fails to crank/start the bike, then the following would have to be checked:
  • battery and battery cables;
  • starting relay;
  • starter motor.
If the engine will crank but will not engage/run, then you need to check for:
  • spark at the plugs;
  • fuel as supplied by the carbs.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Hi,

Appreciate the vote of confidence but there are a few others who are likewise knowledgeable if not more..

On to your concern, it would seem you have two (2) issue, 1st if wont crank and the second will crank but not start.

No Crank: Due to the massive current required by the starter a component is installed between the starter button and the starter. This component then switches the battery to the starter motor. In cars this is the starting solenoid, in most bikes, this is the starter relay. Normally in the starter relay there would be 2 big terminals for the battery and the starter motor cables with 2 smaller wires for the starter switch and ground. Try this - try pushing the start button with the headlights on, if the headlight dims considerably, then the starting relay is good and the motor is bad; on the other hand if the headlight dims just slightly or not at all, it is the starting relay (the one with the clicking sound).

Most starter motor problems could be:
1. the bearings/bushings at the ends of the armature;
2. carbon brushes;
3. commutator segments (the multiple small copper plates that the brush contacts with).

However, it may be to your advantage to simply replace the motor should it be deemed defective, difficult to secure parts or not economically reasonable to go down component level repair.

Will Crank but not fire: There are 2 major requirement for a gasoline engine to fire, fuel and ignition. No fuel could be verified by removing the air cleaner and pouring a small amount of fuel down the throat, start the bike, if it start and runs (even for just a moment), you have verified the fuel problem. No ignition could be verified by removing one of the plugs, reinsert the high tension wire plug to the sparkplug and place the sparkplug atop any metal part, crank the engine, there should be a spark at the plugs.

Pls post back results whether fuel or ignition and we can go further from there.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
