You have a bad battery..... check all out at AutoZone or other auto stores that offer free testing. there are many.
Simple... if it starts with a jump... you have a lack of battery power... bottom line.
you should also check your charging system at same auto center.
good luck

SOURCE: 1999 Yamaha Vstar 650 Custom ...makes clicking noise when trned

i use a jump box on mine most weekends when i wanna take it out, i hook the red to battery and black onto my exhaust and it fires right up no problem. is the clicking noise coming from the fuel pump behind the ignition? it should click for a few seconds then stop. if it stays on then you are not getting enough fuel outta the tank, change the fuel filter and if bike had been stored for winter get a good fuel system cleaner, additive type. if in USA get Berrymans B12, double dose get bike to run hopefully let it stand overnight and all should be fine. fingers crossed. if is is clicking from somewhere else like starter or a relay by the battery, check all the ground terminals you can find

SOURCE: I have a 1999 Yamaha Wolverine. When start button

it sounds to me like you have a faulty terminal, check voltage reading to the relay from battery pos terminal, now push and hold button and recheck on same terminal, if it stays at around 12volts check terminal on other side of relay it this is lower significantly than first side replace again with new relay. of both terminals voltage drops you have faulty battery.

SOURCE: 2008 yamaha r1 keeps shutting off on me. i

First of all you need to make a self diagnose to the ECU in case there is a faul code stored inside.If there is one it will help you to narrow down the problem.
You could also check the right hand switch (kill switch) for normal operation.
A probable cause also could be the fuel pump.When you turn the key on and the kill switch in in "run" position, do you hear the pump working for a few seconds?After you start the engine does it stil work?

Pontiac grand prix 2007 car shutting off, with Start disabled throttle control module.


It doesn't say module , Starting Disabled Due To Electronic Throttle Control !
The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
• Accelerator pedal position (APP) sensing
• Throttle positioning to meet driver and engine demands
• Throttle position sensing
• Internal diagnostics
• Cruise control functions
• Manage TAC electrical power consumption
The TAC system includes the following components:
• The APP sensors
• The throttle body assembly
• The powertrain control module (PCM)
Normal Mode
During the operation of the throttle actuator control (TAC) system, several modes or functions are considered normal. The following modes may be entered during normal operation:
• Minimum pedal value--At key-up, the powertrain control module (PCM) updates the learned minimum pedal value.
• Minimum throttle position (TP) values--At key-up, the PCM updates the learned minimum throttle position value. In order to learn the minimum throttle position value, the throttle blade is moved to the closed position.
• Ice break mode--If the throttle is not able to reach a predetermined minimum throttle position, the ice break mode is entered. During the ice break mode, the PCM commands the maximum pulse width several times to the throttle actuator motor in the closing direction.
• Battery saver mode--After a predetermined time without engine RPM, the PCM commands the battery saver mode. During the battery saver mode, the TAC module removes the voltage from the motor control circuits, which removes the current draw used to maintain the idle position and allows the throttle to return to the spring loaded default position.
Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control however the maximum throttle opening is limited.
• Throttle default mode--The PCM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The PCM will perform the following actions:
- Limit engine speed to idle by positioning the throttle, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

MY SON HAS A TTR 125. IT WONT START. HAS NEW PLUG, NEW GAS, I JUST FINISHED REBUILD KIT ON CARB. ITS GETTING SPARK, ITS GETTING GAS IN SEDIMENT BOWL. IT WILL ACT LIKE IT WANTS TO START AFTER ABOUT 10...


A rebuild kit on a 2004? Why was that needed?
I would do a compression test to verify that the ring, and valves are working for you. Should be above 100 psi. (Throttle open while kicking it over) This may help get you started toward a fix.
