Question about Estes Toys

2 Answers

I can't seem to get the engine to ignite. I have gone through all of the coils. I have pushed them all the way in with no luck. Is there another way to ignite the engine. I cant tell you what a disappointment it has been to do the work assembling it to not get it to launch.

    Thanks Mike,
    I will look for a new power source. when i tested the ignition coil, without it being in the engine, the tip got hot enough to wrinkle plastic but i could hold it in my hand.
    with the right amount of power will it get bright like a bulb filament?

Hi again Jer,

If the igniters are not firing, it's a power problem.

If the igniters are firing and the engines are not igniting, there are a few things to check a well as minor alterations in procedure to try.

Remember: Safety first. Allow cool of time between tests.

  • Double check power from what ever your source is
  • Be sure the igniter is fully inserted into the nozzle.
  • Tape the igniter to the engine to ensure the flash is directed toward the propellant.
  • Switch engines - use a different one
  • Make sure the igniters work on their own without the engin - saves time between tests
  • Try a different style igniter. Century's version is very reliable and is available at Toy and hobby shops.
Good luck

    Absolutely. The filament analogy is perfect. A filament without the vacuum afforded by the bulb would flash brightly and incinerate itself. Not good for a bulb, nut perfect as an ignition source. The nichrome wire they use has a very high resistance, so it gets very hot like a filament.

    For it to work, it should be getting White Hot so fast it practically bursts into sparks of molten metal.

    If you can hold it in your hand........well

    After my first power related embarrassment at a launching, I upgraded to motorcycle batteries, they're easy to carry and talk about response time, press the button, gone. Instantaneous gratification. Just a thought.

    Have fun

Sometimes this problem is because the igniter is not actually touching the propellent. If taping the igniter does not solve the problem you can add a minute amount of flammable liquid to the propellent hole where the igiter is inserted. For example, take 6 inches of kite string and dip the first inch into some gasoline. Hold the string over the propellent hole and squeeze the string from top to bottom using your other index finger and thumb. Once 2 or 3 drops of gasoline have fallen into the hole insert the igniter & plug.

9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.

1996 Audi A4 2.6E - Not idling properly.

The ignition coils on your Audi A4 are what provide the spark to the spark plugs, which sit underneath each coil. Every cylinder in your A4's engine has a spark plug and an ignition coil assigned to it. Sometimes, the ignition coils can fail and require replacement. Typical symptoms of a failed ignition coil include a flashing "Check engine" light, a rough idle or hesitant acceleration. Replacing the ignition coils on your A4 is a quick procedure that takes just a few minutes.

    • 1

      Park your Audi A4 on a level surface and open the hood.

      Remove the plastic rivets that secure the plastic engine cover to your engine with the flathead screwdriver. Depending on your engine, there may be either three or four plastic rivets, which are all very obviously placed. Set the engine cover aside.

      • 3

        Firmly pull the ignition coil you need to replace up from the engine. Since it does attach to the spark plug, you will need to apply a little force. Be sure to pull directly up so that you do not bend the metal rods at the bottom of the ignition coil.

      • 4

        Unplug the ignition coil from its wiring harness. Depending on your engine, you may need to use a flathead screwdriver to pry up the loosening latch on the wiring harness.

      • 5

        Insert the replacement ignition coil into the spark plug cylinder and push directly down until you hear a slight popping noise, which will indicate that it has been installed correctly.

      • 6

        Replace the plastic engine cover and secure it with the flathead screwdriver and the plastic rivets to complete the procedure.

    My 2005 Dodge stratus will not crank. It was sputtering this morning when cranked, and the engine liht was on. I took to advance auto to put on tester. They told me the heating coil or the plugs. I buy...

    Well, let see, see if you hear fuel pump hissing or a click once you turn your key to the "on" postion. If so, then fuel pump is building pressure and is working, if not then fuel pump is the promblem and please check your fuel pump relay before actually considering fuel pump failure, secondly could be your ignition coil that's gone bad, I don't really know how to test this, but heard you can pull the spark plug out while still instact with the spark plug wire, position it about 1" away from a ground unit, such as your engine valve cover which is the metal part, or ground to see if there is a spark.... this is only on older model when the ignition coil is relayed within the distruburator. However seems by what advance auto diagnostic, seems like it the ignition coil that gone bad and needs to be replaces.

    Engine won't crank or seem to get power on key turn.

    More than likely, your starter has gone out. If the battery is fully charged and its not even turning over, that is what i would start with.
