The starter solenoid is most likely faulty and not carrying enough amperage to the starter motor. Regards Phil
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The clicking noise comes from a part called the starter solenoid. The solenoid connects the battery to the starter motor when the solenoid is energized. The key switch and the safety switches in the starter circuit combine to energize the solenoid. If the solenoid is clicking, the circuit that triggers it is working.
The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power. Only when it transmits enough current to the starter, the relay starts to work.
Usually a rapid clicking noise is a good indication that your starter motor isn`t getting enough electrical current to engage – basically your solenoid is trying to engage but can`t make the connection.
If you only hear a single click as you try to start the car, it could be an electrical problem with the starter solenoid or starter relay. A faulty or corroded starter solenoid tends to absorb the electrical current meant for the starter motor.
One possibility is the solenoid. A single “click” sound comes from the engine compartment or from under the car. This could mean that the solenoid is trying to engage but that the internal components are stuck and unable to work properly. Repeated “clicking” sounds usually indicate a dead battery.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
A single loud click could mean that there are troubles with the starter motor or the starter solenoid—which together act like a crank to help get your car`s engine going—or more specifically from a failing or bad starter relay that`s not sending enough electric current from the battery to the starter motor.
Common Signs of a Bad Starter
The engine won`t turn over. The most common signal that your starter has a problem is if nothing happens when you turn the key or push to start. Unusual noises, such as clinking, grinding and whirring. If you ignore these sounds, it can eventually lead to damage to the engine flywheel.

Wont start no ignition put new plug in and fuel filter
Flush gas tank, fill with fresh gas and Stabil. Replace air filter. Remove bowl from carb clean bowl and holes in bowl screw.
Cranks up and runs fine ,then starts cutting out then runs fine and starts cutting out again
I am no pro but my suggestion to you is if you have changed your spark plug recently check the gap on it and make sure it is right and make sure is the right spark plug for it. Also check the oil if it is low the motor as it gets hot will start to sputter or if it has to much oil it will have an air lock and blow you Lhead gasket after a while. Another thing to check is the air filter to make sure it is clean and check the timing with this if you don’t trust your self ask an repair expert for your brand of mower.
I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.
Brand new electric power Weed Eater lawn Mower, started up like a champ, started vibrating and was loud, shut it down, now it won’t start. Checked the extension the outlet all seems fine. Didn’t even use it yet. Why will it not start?
Battery no good from factory bad battery connection maybe put together on a Monday or maybe battery internal charger no good
Craftmans 3000dlt ride on mower can’t start it up all it does is click click changed the selenoid and starter still click click Ammeter runs to negitive when i try to start it and it’s a brand new battery driving me batty someone said it could be the electric something on the carburetor .but wouldn’t the starter a least still turn
The starter itself may be bad. Take the starter off, connect it to the battery on the mower with jumping cables + to + and – to battery and ground other to starter. It should spin as if it was going to start the mower. You may have to try different places on the starter for a good ground. If the starter spins, then it’s not the starter, but binding. If it was electrical such as seat switch or blade switch it would still turn over but not start. With the starter clicking, it sounds to me that the solenoid is fine.
My battery is only 1 year old, i cant get it to hold a charge
My battery had the same issue. I opened the WA3218 battery box and found one of the two 12V 10AH batteries had overheated due to an internal hot spot. You can either buy a new WA3218 battery from Sears for about $82 or if you are a handyman save a few bucks and change the two Model 6 DZM -10 batteries for new ones at about $25 each. Need to change both at the same time. The battery wires are soldered. Either cut them off and crimp on new HD yellow terminals or un-solder & re-solder them. I found a 12V 15AH replacement (50 % more capacity) model UBS12150 which will fit inside the battery box for about $37.50 ea. Peter
I have trouble starting a toro walk behind mower
All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!
My toro 6.5 hp push mower (2010), has no fire to the plug. I have not abused it. i have a small yard and it just gets normal use. Now it won’t fire. I first changed the fuel and cleaned the carb thinking it was that crappy ethanol again. but i grounded out the spark plug and cranked it…no spark. I think it has to do with the lever you pull back to start it . they have some stupid complicated safety contraption that rides along the fly wheel when you pull back on the handle for starting and shutting off the engine. …it looks worn out already…like a mini brake pad. any ideas?…do i really have to replace this garbage every year or am i on the wrong path here?
Unhook your wire from the coil that goes to shut off mechanism, and see if you have spark then. the wire may be grounded out, or your coil might have took a ****
