SOURCE: Electronic Fuel Pump

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.

It seems likely that your fuel pump is not operating, you should hear the fuel pump priming when you turn on the ignition, if not the fuel pump is at fault, this is not uncommon and a replacement is the answer.

SOURCE: Press starter button then a crackling, clicking sound in Relays

You might first try and (jump) the starter at the starters bendex. To do this you could use a jumper wire or a screwdriver if you know what you are doing... (jump or connect together) the one (thin) red wire leading to the back of the starters bendex and the one (thick) cable also leading to the back of the starters bendex...being careful not to "ground" your jump wire or screwdriver to the bikes frame!!!... "Make sure you are in neutral"!!! ...Turn the ignition to the on position. You may have to engauge the start button at the same time you jump these leads. If your bike still clicks instead of turns over/starts.. Either the battery is not up to snuff...try boost starting from off you car or truck to determine this if you do not have the proper battery test equipment: (or) there is a loose or corroded connection. It is possible the connection at the starter button also is crusty. To clean your connections well, "You must first disconnect the negative terminal at the battery"!!!... Clean all the contacts/connections the same way using an electric contact cleaning spray (that evaporates) and a med-soft bristle brass wire brush. You really should start from the battery to the starter and also the starter button if accessible. A light wipe over from a clean cloth sprayed sparingly w/a light oil or silicon afterwards on all cleaned areas should keep them being that way again till next year if your bike is ridden in fowl weather often and/or left out in the elements. I find it hard to believe that all the relays went out simultaniously!!!...It is almost impossible. Guzzi-Guy

Cranks doesnt catch, no fuel pump prime

Hi, Newbeemech are you a parts replacer or a wanna be professional? Check for continuity at the fuel pump fuse and the system relay switch otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Bike has problem starting think its fuel

Basic riding procedures can be overlooked even with experience riders. Adv to check petcock , should be on ON position, not on reserve or closed. Check Fuel pump (check fuse /relay location on manual replace as needed) ? hopefully you don't need a fuel pump , Fuel Filter ( replace ) .
If bike was not running for a period of time, decomposing gasoline can cause injection to gum up preventing gasoline to flow properly and thus no gas no combustion.

Adding high grade gasoline along with injector cleaner may due the trick.In addition heads may loose compression if bike was sitting for a long period of time. Make sure no debris is blocking air intake or heads vents( refer to manual)check oil level and then ride the bike until head fully compress ( about 2-5 miles) .
If problem persist provide more information along with any changes you have done to bike and more details about issue.
Good Luck

Injector not working why put new injector new computer new fuel pump does it have injector relay 1987 celebrity

Check fuel pressure. Have you replaced the fuel filter on schedule? Verify that the fuel pump is getting power. Power goes through an in-line fuse, then the fuel pump relay or the oil pressure sensor. (The relay bypasses the oil pressure sensor while the engine starts, but fuel pump power goes through the sensor during normal run operation. If you lose oil pressure, the fuel pump is shut off to protect the engine.) On four-cylinder models, the fuse is in the fuse block (E PUMP 10)
The fuel injectors are connected to the ECM fuse on one side and straight to the engine computer on the other side. Check the connectors and wiring, especially at the injector.

2007 buel lightning 12Ss How do I unclog the fuel injectors I have replace the fuel It could be the fuel filter. I been over sea's for three year.

Drop the fuel pump out of the bike and drain it. You might have to buy new injectors and a fuel pump. The fuel pump has a trap door to get to it - Google and download the buell factory service manual for your bike.

No fuel from my injectors, my fuel pump is not engaging.

Fuel pump power comes from a relay which is usually under the hood but not always, it can also be behind one of the kick panels next to the drivers left foot or passengers right foot. Are you getting power to the injectors as injector power usually comes from a different relay or direct from the ignition switch. The injectors are grounded by the control module so they should have power all the time or when the ignition is turned on. Check out the relays and also check the wiring harness connectors both under the hood and through the firewall. Next, check for the various engine signals to the control unit. If a cranking or cam angle signal is missing, the control unit will disable the injectors and fuel pump.. buy or borrow a copy of the workshop manual (try the local library for this) as most have the procedures and test methods to check for issues..

No power to fuel injectors

Determin if the injector operating:
  1. disconnect the injector electrical connector and measure the resistance of each injector with an ohmmeter. Compare the measurement with the resistance value Specifications are 11 to 18 ohms.
  2. Replace any injector whose resistance value does not fall within the specifications.
If the injector was not operating but the resistance reading was within specifications, the PCM Powertrain Control Module (PCM) or the circuit to the injector may be faulty.

Check the ignition fuse located in the engine compartment fuse center. Also. check the fuel pump relay.
Note: The fuel pump relay is located behind the radio in the center of the instrument panel.

If the relays are good and the fuel pump does not operate. check the fuel pump circuit. If the wiring and the connectors are
good, replace the fuel pump.

Its your fuel pump if you can't hear it. And its inside your tank. Not a hard fix if you have a book that tells you how to remove it. Alot of procedures to follow to get it right. And yes it does work off a relay.

200 sx not getting fuel to injectors

It could be a bad fuel pump or wiring to the fuel pump, but it could also be a clogged fuel filter. If the fuel is getting to the injectors but not into the engine, the injectors may be clogged and in need of replacement. There are repair manuals that can help you find and replace your fuel filter, which should be replaced at regular intervals (depending on your service schedule), and these manuals can be found at the library or auto parts store. The most common manuals I know of are Chilton and Haynes. Both are made for your exact vehicle and have the steps to fix any problem, down to a complete tear-down and re-build of your car (including injectors).
