I would replace the ignition control module, this year has a very simple CDI electronic ignition system, that is about all that i have heard goes wrong, the module should be under the seat, just follow the crank pickup wiring to the module, remember most of the experts on fixya most likely weren't born yet when this bike was built.

Lights come on strong, bike won't start. when i push the starter button and hold it down and then pull in the clutch a large banging sound comes from inside the right side of the gas tank.


Hi Noah, It's either fuel OR electrical, First check both spark plug and coil.. Pull spark plug out and visually inspect for any dirt touching both electrodes... Next, Plug the spark plug back into the spark plug lead and earth it to the motor(make sure the spark plug is touching metal)then try turning the motor to see if the spark plug is sparking...
Also the link below is a short YouTube video showing the right colour spark and it should spark over the top of the centre electrode,
How to check for Spark Plug Fire in any engine
If it does spark then it's a fuel problem. You need to pull your carby off and unscrew the bottom half from the top, 1st sign of a needle stuck inside the seat is a dry carby There you'll find the float, push the float up and down and see if the needle above the float slides up and down from the seat, If the needle stays up then it's stuck and NOT letting the fuel into the carby, Just pull it down with your fingers to loosen it up..I hope this helps.... CHEERS..

Kohler courage 6.5hp wont start?


Could be a short in the coil for the sparkplug. Check the magneto- pull the plug wire off the spark plug and hold it close to the frame of the while someone tries to start it. Keep all parts of your body clear of the mower- only hold the sparkplug wire. When the motor turns over, verify spark from the wire to the frame. If no spark, you likely have a bad magneto coil. If you have a good spark, try taking the air filter off and use some engine starter fluid (not much) and then try and start again. If it starts and runs for a second with the starter fluid, you probably have a problem with your fuel not getting in, which leads to troubleshooting the carb and intake.

Suzuki wagon r+gl check engine light keeps flashing and wont start after battery change


the engine (there are more than one engine)
has a distributor.
"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

I Got an speedlink SL-4451-SBK for ps3 and it wont connect


This works: Turn ps3 on. Plug the controller into the usb cable and into ps3. Then plug the dongle into other usb port. After a short time the dongle will flash quickly (this means it's in pairing mode - when the dongle flashes slowly it's too late). Press the PS/Home button as soon as you see the dongle fast flashing. All the LED's on the controller will begin to flash and after a short time one (or two) will remain solid. Immediately disconnect the charging usb lead from the controller and again the LED's will flash, push the PS/Home button again and after a short time one or two will remain solid. The controller should now be working. If the controller fails to respond repeat this process but make sure that you disconnect the dongle and reinsert (so you can see the fast flashing lights and try again).

Cbx 550 fires on 3 cyclinders for about 2 seconds the dies, wont run for a period of time, i cleaned the carbs, also the bike had been sitting for about 4 years, any help would be great.


Clean fresh gas? Checked the spark? The spark plug wire ends should be replaceable. They usually just twist, or unscrew, from the wires. They can get corroded or just plain wear out just like a cars spark plug wires do.

I have two yamaha tw200, the problem are, when i push the start button the start engine running but it wont kick in and turn the main engine. what can be the problem? the wierd part is when i have an...


I ha d a similar problem, so try the following. Screw out the spark plug and check its function. If it gives spark only BEFORE and AFTER eletrical starter works (when you push+relase the starter button) it means you have a weak battery. It doesn`t have enough energy to rotate the starter and give spark at the same time.

1995 kaw jet ski 750st push start button and it just clicks it was running great new battery and new plugs


Open the electronics box and jump the solenoid . If the starter works you have a bad solenoid. If you hold the starter button and tap on the starter, and the starter works , you need starter brushes. If the starter has burnt coils, has a shorted armature , or is wet inside, you need a new starter.

1999 Subaru legacy will not start


Check your terminal connections, if they are loose they will need to be inspected for breaks. If they are broken you will need to replace the connection. Make sure they are clean and free of corrosion.

Other possible Problems
If the car wont turn over your starter could be bad.
If it turns over but wont start it could be any number of these problems.
Coil Pack
Plug Wires
Spark Plugs
EBX (Engine Brain Box)
CBX (Chassis Brain Box)
Crank Sensor
Fuel Pump
Fuel Rail
Fuel Injector

Good luck
