It,s not getting spark - Craftsman 22" Gas Hedge Trimmer

plug fouled with oil ? try a new plug , b sure to set correct plug gap as well on new one

Either has a bad injector or the wiring to that particular injector has been pinched or skinned and grounded somewhere.

Check battery voltage, remove spark plug suppressor cap from HT lead and see if spark is good by holding lead in a gloved hand and placing the lead end near the engine. If spark good get a new suppressor cap. Check the plug shows a good spark in the new cap by holding the screw thread to the engine. Poor spark change spark plug. If you get a poor spark from the HT lead then get the ignition coil checked.

Your question needs some additional details. Are you sure that it is not getting fire to the cylinders or are you just using the term "not getting fire" because you are not getting any response from the engine when trying to start the car? Does the engine turn over? I would assume that it probably does based on your question. If your engine turns over then the first diagnostic step to see if you are getting "fire" (spark) to the cylinders is:
- Remove a spark plug wire and remove the corresponding spark plug.
- Put the spark plug wire back on the spark plug.
- Now hold the spark plug thread against a metal part of the engine
- You may want to use rubber gripped pliers to hold the spark plug
- Have someone turn over the engine.
- Watch the end of the plug to see if you are getting a spark jumping the gap to the ground electrode (little metal arm suspended in the air at the end of the spark plug).
- If you are getting spark then you are getting fire and your issue is most likely fuel related or timing (spark synchronization to the cylinder cycle).
- If you are not getting spark, then you have electronic/electrical issues

Let me know what you find out...

The issue is spark yes/no. The color is not really relevant. Any spark will usually fire the mixture.

if you get a shock holding it put no spark at the plug the coil might be week

(Make sure you have a working spark plug.)

Take the spark plug out. Hold the plug, or have a friend hold the plug, to the engine. Pull the rope and see if you get spark to the plug. You may need to get in a dark area so the spark can be seen. If you get a blue spark, that is good. If you get a white spark, that means the module is weak. And if you get no spark, that means it is bad.

Good Luck!

First get the spark plugs, then get the right swivel socket for the spark plugs and a gapper for the gap of the spark plugs.

Remove the boot, from the first spark plug, and..

Unscrew each spark plug one at a time (making sure not to mix up the spark plug wires) using a ratchet and extension, and the swivel spark plug socket by turning counter clockwise.

Carefully gap each spark plug, if needed, and insert by hand and slowly screw in each spark plug, making sure not to cross thread.

Put the boot back on to each spark plug, making sure that you squeeze down the connector a little bit to ensure a good tight connection.

Remember, replace one spark plug at a time and replace the boot in order to not get the firing order mixed up.

First, you must find out if your getting spark or not. Remove plug, and ground it to the motor and pull cord, see if your getting spark. If you are, then your problem is your not getting fuel. If your not getting spark there are a couple of things that can cause this. !st, defective spark plug, Second, cable from control handle to engine may have stretched and is not releasing the kill switch. Disconnect the kill switch wire and check to see if you have spark, if you have spark, replace engine control cable. If with kill switch wire disconnected you still have no spark, you would have a defective magnito coil, which is rare, but does happen. This engine control cable kills the spark when you release the handle and also is the engine brake, It serves two functions.

May have no spark due to a bad crank sensor, which is responsible for spark when it gets a pulse through the cars' computer.
