Re: rc car will not start
There are two main factors in making an engine start. First, the glow
plug must be working. This means that when 1.5 volt is applied, the
filament will burn a bright orange. A bad glow plug will not generate
enough heat to burn the fuel/air mixture in the cylinder. Second, the
engine cylinder must have the correct fuel/air mixture when cranking
the engine (via pull-start or bump start). If there is no fuel in the
cylinder, the glow plug has nothing to ignite. And if there is too much
fuel in the cylinder (i.e. flooding), even a new glow plug will not
have the energy to burn the excess fuel.

I have similar problem different vehicle, my ignition was not connecting well and the glow plugs were not initially getting properly hot, not sure how to fix it/ I disconnected the battery entirely and unplugged what I could and switched # 1 for #3 plug and waited overnight and charged the battery out of the truck, next day put all back and attached battery and started right up right since , so try take out battery and charge better first.
you need to pull the glow plug out and see if its good visually; look at the coil in the hole in the bottom it should look like a spring unbroken. If you have a glow stick put it on the plug and see if it glows. If you can just replace the glow plug they go bad and it may still look fine.
you need to set your main carb needle to 3 turns out from closed.
Now with the glow plug out place a clean rag over the cylinder head where the plug came out of and use you starting wand to turn the motor over........the rag is there to keep fuel from spraying in your eyes. turn the motor for 5 seconds.
Next put the plug back in and gently tighten it down with an 8mm socket. Put your plug wire back on and try to start the engine for 3 seconds. If it starts up reves high then dies try this.
Put your finger over the exhaust and turn the motor over until you see gas go into the carb the remove your finger from the exhaust and continue to crank the motor for no more than 10 seconds.....she should start now. Adjust the carb according to the manual. Have fun.
check to see if the engine has
compression by taking glow plug out and putting finger over the hole and pull the pull start it should pull your finger you will be able to tell if it is without compression it wont be able to pull fuel in there for it wont run
Hi You've checked the glow plug externally to see the wire get red? If so, as long as you've got fuel and fire then it has to start. My guess here is that you have either a bad glow plug, low batteries, fuel air leak or clogged pressure line. Put a charged battery into the starter. Remove the glow plug and try to start - fuel should spurt up through the glow plug opening. Now connect the glow plug and touch it to the engine. Try to start and you should see the glow plug wire glow red. (do this only for a second. Now disconnect the pressure tap from the muffler and try to start. All else fails, replace the fuel line to the carb and the pressure tap. Your carburetor can leak air through the rubber gasket . Also, Traxxas fuel tanks have a cracking problem. Good luck
Motor could be damaged from getting too hot. I would try to reset carb settings back to neutral from the factory. The manual that came with the car should tell you how many turns out they should be. Also check the fuel lines to make sure they did not get damaged. Nitro motors normally run best at 210 - 240 degrees. Much more than 240 degrees can damage the motor. It is always better to run a little rich than lean.
Hello. The interesting thing about these small motor cycles is that their charging system is not adequate to keep the battery fully charged. I recommend that you charge the battery fully and then start it. When the battery is totally dead, even a kick start will not start it. The charging process may also indicate that your battery needs to be replaced. If you are still using the original battery on a 2005 I would begin by having that battery tested at any auto parts store.
Have you charged the battery in the EZ Start wand? If you have is the motor turning over at all? If the motor is turning over but not firing it could be the glow plug. If the motor trying to turn over but won't, the engine might be flooded. If it is flooded remove the glow plug and turn the truck upside down. Fuel will run out of the engine. If fuel runs out of the engine, put the truck back down on its wheels. Cover the engine head with a rag and turn the engine over with the EZ Start wand with the glow plug still out. This will remove all excess fuel from the engine. Reinstall glow plug and try to start again.
