when jump to starter direct but not firing.?
Garden

Experienced gardeners share their insights in answering this question :
From your description, I’d still predict that it’s a battery problem… Jumping juice directly to the starter bypasses the ignition circuit. The engine will turn over but unless the ignition is on it won’t start…
Give the battery a good 24 hr charge and see what happens.. In future take the key out of the ignition when you’ve finished with it.. (I’m always leaving my lights on)!

Check/clean/tighten all connections on battery/solenoid/starter/Ignition switch and neg(-) cable to frame or motor. Check to ensure all safety features are working properly and not engaged. Check for an inline fuse, bypass solenoid to see if engine cranks if it does replace solenoid, if no crank replace starter.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
The most common cause of your mower engine not starting after a long period of storage is stale fuel, but there are many other possible reasons there could be a fault. Our advice is to contact your local lawn mower servicing provider for a professional inspection.
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.
If it is difficult to start the ride-on mower, the most common reasons include: Old fuel; make sure to use fresh fuel, especially after winter storage. Spark plugs might be dirty or damaged. How to examine and replace a spark plug on your ride-on mower.
Higher temperatures create higher resistance to the flow of voltage; that`s why coils usually fail when the mowers are hot and start working again when the engine cools.
A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.

Riding Mower Clicks but Doesn`t Crank

When you hear a click as you turn the key, a weak battery, bad starter solenoid, faulty wiring, failed starter motor or a seized engine could be the cause. This DIY troubleshooting will help you figure out what to fix.

Bad starter motor: If you hear a single click when you turn the key, but the engine won`t start, that could mean there`s a problem with the electrical system. The starter motor is responsible for physically turning the engine over and getting the engine to fire. If this is the issue, you`ll need a new one installed.
If the engine will not crank, you likely have a problem with… Discharged / defective battery or faulty electrical connections. To address these issues, check the battery and charging system for problems. Faulty parts: potentially the safety interlocks, starter motor switch (open circuit) or solenoid.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

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?
ANSWER : 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 ****

Battery goes dead over night – Toro 42'' Zero Turn Lawn Mower Trailer Package Deal ()
ANSWER : First thing to do is find out if it’s the battery or the mower. Disconnect the battery and leave it overnight. If it’s dead in the morning, you need a new battery. If not, you either have a charging problem (not likely if the battery isn’t dead after using the mower) or you have a current drain.
