Check the fuel filter, you are not getting fuel so therefore the spark is not getting anything. You can also take some carb cleaner and clean your carb. This is a common carb issue and it needs either a new filter(recommend) and also some carb cleaner shot through the system

The problem would be that little module you are down to It is rarely the coil A lot of the time you can replace it with a module from an earlier victa 2 stroke, Or if you want to go genuine you can download a parts list from shindaiwa.com. Thats where i got mine from .

Check the wire that goes to the "OFF" button. See if it is by chance loose or cracked allowing a short. Beyond that, it would probably be the coil, but I would lean towards some type of a short, especially if you know the plug is OK.

Got 86 Toyota pickup 22r getn no spark changed igniter,coil, plugs, and wires and did inline spark test still no spark need help!!!!


Sounds like you have concentrated on the HT items.
Time to go back and check out the LT circuit from the ignition switch through to the points in the distributor.
disconnect the feed going to the coil from the ignition switch. Switch on the ignition and 'flash' the lead to earth (ground)
You should get a healthy spark you would expect from the battery. If all is OK switch off the ignition and reconnect the lead. Remove the distributor cap. Worth checking the spring loaded carbon brush in the top of the distributor cap at this stage
Rotate the engine until the points are closed. Switch on the ignition and with a small insulated screwdriver open and close the points, a healthy spark should be seen every time you open the points. Check the condition of the points while here to make sure there has not been an excessive build up due to arcing, Clean or renew if necessary, Some distributors are fitted with a capacitor near the points - these can break down in time and always suspect.
If the spark across the points is good get a friend to turn the engine over while you watch the points. A good spark should be seen every time the cam opens the points. Clean the corrosion from the rotor and the segments on the distributor cap.
Sometimes the points are badly adjusted and prevent a good spark or the heel that runs on the cam gets badly worn.

Husqvarna 235r brush cutter starts fine when cold but won't start when hot


If it has spark and fuel then it may be worn, causing low compression and too weak to start. .

How do you check the spark on a Husqvarna 240 chainsaw?


Buy yourself a spark tester from the local chainsaw dealer, these will clip to the cylinder to create an earth, the plug cap fits to the end, it will have a large gap to load the ignition unit, if there is a spark when the engine is cranked the unit is ok.

Changed fuel pump. getting fuel to engine. but will not start.


Check for spark. Maybe a crankshaft position sensor is bad or a module.

Secondary Spark Test This spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

Ignition Coil Testing
  1. Remove suspect coil.
  2. Disable fuel pump by disconnecting inertia switch electrical connector.
  3. Reconnect the ignition coil electrical connector to the coil.
  4. Install spark tester 303-D307 (D81P-6666-A) or the equivalent.
  5. Crank engine while observing the tester.
  6. If a blue-white spark is not observed replace coil.

Removal & Installation To Remove:
  1. Remove the air cleaner outlet pipe if interfering.
  2. Disconnect the connector from the ignition coil. coilconn.gif

  3. Remove the bolt from the ignition coil. coilbolt.gif

  4. Remove the ignition coil on plug.
To Install:
  1. Install ignition coil on spark plug.
  2. Install ignition coil bolt. Tighten to 10 Nm (89 in. lbs.). coilbolt.gif

  3. Reconnect the ignition coil electrical connector. coilbolt.gif

  4. Install the air cleaner outlet pipe if removed earlier.

My saw won't start. how can i check the ignition?


pull the kill wire off at the ignition coil - retest for spark , if now spark faultry kill wire or switch indicated
but if no spark fit spark tester in line with h t lead and spark plug

gap tester is basically a piece of wood with 20 mm hole in middle and a hole drilled through to centre from opposing sides
the a nail that fits firmly is pushed through 1 on each side
and meet in the middle of the hole , but the points of ecah nail must align together and be exactly no less than 6.00 mm apart from each other ( place the tester inline between h t lead and plug ) use whater adaption you may need to connect to the saw
and pull the engine over as you would

if all is well the spark should jump across this gap and the gap at the plug while under compression pressure

you will see it in the the tster window

if no spark coil is problem
replace coil and set air gap to 0.010" and refit wires ands covers

cheers hope it helps

Cap on gas tank leaks. leaf blower stops after using for 5 minutes and then it doesn't start until it cools off


sounds like the breather on cap is faulty , replace cap

the stopping is most likly a coil going open circuit when hot
and is not producing spark

best way to test is to place a home made tester in line with the h t cap and the spark plug and re run and see if spark fails when hot - then retry cold if spark returned - faulty coil is confirmed

to make a tester

cut a hole of 20 - 30 mm in diameter in a 2 " square piece of wood - drill a hole ( using 3.5 mm drill bit ) in opposite sides all the way through to the centre - then fit a nail that has been sharpened to a point into each hole you drilled
now push the nail points together in the centre of the large hole you cut so that the pointed ends are no closer than 5.00 mm
apart ( you may need to cut the nail heads off )

fit this in between the ht lead and the plug tip
and you might need to tape the unit up so that it stays in place
while you test

try making tester because you can use it on other things as well

cheers

No spark to the plugs or the coil


Troubleshooting No Spark Your new engine won't start or your old engine suddenly quit and won't run. You're pretty sure there is no spark but how do you determine what the exact cause is? Definitely do a test for spark at the plugs. Remove one of the plug wires from a plug and hold it near grounded metal. (If the plug end has a long insulated shroud, you may have to improvise to get ground close enough to the end of the wire.) Have someone crank the engine while you watch for spark. If you get an 1/8" or so of spark, that should be enough to fire. If you don't have a helper, you can do it this way: Pull the hi-tension lead out of the distributor cap and hold near ground.
With ignition On, turn the engine pulley CW past the TDC mark. You should get some kind of spark, although if you turn slowly the spark may be weak.Check the distributor cap inside for signs of cracks or carbon arc tracks.
Also, check to see that the little carbon contact for the center terminal is in place; without that you can have spark but it won't get to any plug wires!It's rare, but a rotor with an internal short or carbon tracks on the surface can kill the spark before it even gets to the cap.

Quick review: The coil is a big transformer with a magnetic core. Current from the battery goes into the primary winding on Terminal #15. That same current goes out Terminal #1 and through the point contacts. This current creates a magnetic field in the core of the coil.When the points open, the magnetic field in the coil core collapses, creating a high voltage in the seconday winding, which is fed to the center Hi-tension terminal. The condensor across the points helps to control arcing at the points, which would soon destroy them, and also makes the spark a higher voltage by creating a resonant (ringing) circuit with the coil winding. All we really need to know is that without the condensor, the spark would be pretty weak.
Troubleshooting: You can find out quite a lot about the coil circuit with very basic tools. A voltmeter is helpful (I prefer the older analog meter with a needle over the digital ones because changes in readings are more easily seen.)If you don't have a meter handy, a simple test lamp will do just as well. If your car is 12 volt, use a 12 volt bulb; if 6 volt, use a 6 volt bulb. Put some wires on the bulb, maybe with alligator clips, and you're in business.Connect the tester (meter or bulb) from ground (engine case) to Terminal #15 on the coil. Never mind what the actual markings on the coil say; connect to the terminal which has the thick Black wire from the main harness on it. I say never mind the markings on the coil because someone may have swapped wires around which could lead you astray.The tester should show 12 volts (or 6v). If it doesn't, there is no power from the Ignition Switch. Track that down (bad switch?).Double check that there is power at Terminal #15 while cranking the engine with the key. This is important because sometimes power will be lost while cranking due to a contact failure inside the ignition switch.OK, you have power going to the coil. Now, hook the tester from ground to Terminal #1 on the coil (where the Green wire from the points connects).Leave the Hi-tension lead out of the cap. With ignition On, turn the pulley by hand (or have someone crank the engine). The tester should go On and Off twice each revolution. If it does that, you should get spark.If the tester stays ON while cranking, the points are not closing. Watch them while turning the pulley to see if they appear to close. If they do, there may be a surface film on the points or the points are eroded and pitted. Replace the points. I strongly recommend using Bosch points as many of the off-brand points give very poor life. In a pinch, you might lightly file the points. When replacing points, be sure to put a tiny amount of grease on the cam lobes or else the fiber rubbing block will rapidly wear and change the point gap. One other rare cause of an "open points" condition is failure of the tiny braided pigtail lead which grounds the advance plate. If the pigtail is broken, the advance plate may only be intermittently grounded. This will cause loss of spark as the advance plate moves or maybe no spark at any time. (There is no pigtail on distributors which have no vacuum advance.)If the tester stays OFF while cranking, there are 3 possibilities:
Points shorted (stuck closed).
Condenser shorted.
Coil open.Take the Green points wire off the coil terminal. If the tester now goes ON , either the points or the condenser is shorted. Replace both.If removing the Green wire still did not turn the tester ON , the coil may be open.
Double check that there is still power to Terminal #1 on the coil. Also look to make sure that there are not any other wires connected to Terminal #1.
(Sometimes, someone will mistakenly connect the Backup light wire to Terminal #1; this will cause no spark when in Reverse!)
Replace the coil if the above test shows the coil open.

Car just stopped running. Lost power suddenly.


Find an inductive pickup indicator for spark. Place on distributor cap to see if spark is at coil internal tower. If no spark at internal tower, look at ignition module or pickup coil. Ignition modules are prone to failure on 626's. But if you have spark at tower but not at the wire end, then your rotor is gone.
