- In this video I demo how to quickly check if you have fuel issue and how to check the fuel pump and fuel shut solenoid.
If your mower engine does not turn over at all check this in this order:
Battery conditon
Battery connections tight
Main fuse
Check is starter is getting power:
Yes- Replace / rebuild starter (bench test to verify)
No- Check ignition switch and relay
If you mower turns over but not starting? check this:
Battery Condtion
Battery Connections
Check fuel level & quality
Check fuel delivery:
Fuel pump working?
Yes- Check fuel shut off solenoid
Shut off solenoid working?
Yes- Check Carburetor
No- Replace solenoid
Fuel pump NOT working: Check vaccum hose is not damaged if vaccum hose is good check fuel lines and clear any line restrictions or cloggs before replacing pump.
If your getting fuel properly and engine is still turing over but not starting, check ignition system:
*Spark plug condtion
*Ignition coil (use coil tester)
* Ignition Switch / starter switch
*Check all safety switch connections
* Pto swtich (may be sending false signal that blades are engaged.
* Relays
*Flywheel key way could be sheared causing timing to be incorrect.

I tried everything
New plugs
Fuel filter
Changed lines
Air filters
Then your selenioid problem solving popped up
I didn’t remove it but tapped it with a wrench a couple times.
Vrrrroooom! Fired right up the pin was stuck tapping released it.
Thanks!
Mahalo for the video. You helped me fix my mower. You are a lifesaver. Instant subscriber.
What an excellent tutorial. Well done - thank you!
Thanks for the ideas. My zero turn wasn't getting any fuel through the lines. I blew in the lines and opened the choke on the carb a few times. It fired right up!
Thanks so much!! Test light routine helped. No definite fuel delivery. No "click" to solenoid. Blew air back through the line before the filter, then tapped hammer on solenoid, and ALL is good now! Feeling the solenoid "click" is a good hack. Not sure which problem I had, but my E130 JD is now running fine. Thanks so much!
Good deal Douglas! Sounds like the fuel shut off solenoid was stuck. Its a common issue especially if it has not run for a while. They get gummed up over time and will not let gas get through the carb. Many times just removing the valve, freeing it up and cleaning the valve with a wire brush and WD-40 will do the trick. Thanks for watching. Dont forget to subscribe.
That was my problem.. Wow! Thanks for the information.
Thank you for this video! Saved me a headache and money!
Great video , thank you .
Answered all my questions perfectly.
Great to hear!
my z355r john deere was shutting down after 20 mins. i had changed fuel filter, air filter, no help. I blew out lines i could, no help. I took off solenoid and checked it was working so i cycled it a few times out it back on and problem fixed. thansk
Thanks for the video !
Thanks. GURU . FOR THE INFO .I HAVE ALL YOUR VIDS . ILEANT A LOT . I AM SEMI BLIND
That you for your response. I will try some carburetor cleaner first.
Think you just saved me a lot of money. Mower kept stalling time running kept getting shorter. Just went out gas filter full ran for about 5 min it stalls and gas filter is half empty. Has to be a clogged line.
Make sure the tank ventilation line isnt clogger also.
@Mechanical_Mind took the fuel line off hardly any fuel coming out. Blew a little air in it started pouring out. Just cut for a little over an hour after that. I'm going to change them all next chance I get. Thanks buddy.
You just saved my day! Awesome job
I have the same mower and it just cut off when mowing today and I checked for fuel and I’m getting fuel to the carb so I’m guessing the solenoid is my problem.
Thanks very good video- well done!
Remember the fuel line. Ethanol eats the lines.
First off I really appreciate your videos. You have some great indepth content on Deere mowers. Would there be any chance that a failing fuel shut off solenoid would cause a near stall of the engine? I have a 2014 Z920m and it will bog down and nearly stall when I reach top speeds. This occurs regardless of the blades being engaged or disengaged. I have a new fuel filter, fresh non ethanol blend fuel, new spark plugs, and the battery is holding a charge. Engine seems to start and idle fine.
Thanks Kevin and for watching the videos. When the fuel shut solenoid fails it will not let get through the carb. It sounds like you might have either a vacuum leak around the carb, intake gaskets. Or a fuel tank ventilation issue.
In this video I show how to find vaccum leaks czcams.com/video/NGAQDAx6oVA/video.html.
If its a tank ventilation issue run the engine unitl is starts to stall then remove the fuel cap and see if it clears up. Your mower has a ventilation hose running next to the fuel line. When they get clogged it doesnt let air to enter the fuel tank and the fuel pump is then fighting the vacuum in the fuel tank and cannot provide enough fuel needed for the engine at higher rpms.
@Mechanical_Mind I have been wondering about a vaccum issue. Have you ever dealt with the Z920m that has a Carb Cannister? According to Deere parts website I have the California model fuel system with the big charcoal cannister. I wonder if that may be part of my issues.
Excellent video. I have a Z930 that shuts off after running for about an hour. It sputters down to a stop. I noticed that even though the solenoid was tight on the carb the body of it turned when I was unplugging the connector to test it. Could that cause the turning off?
The body of the solenoid being able to turn is normal.
It sounds like your tank has a vetnaltiion issue or a partially clogged fuel line. Remove the fuel line and vent line and blow them out with compressed air.
Will do. Thank you so much for your time to help those of us in need.
OK I will do that
Question: You checked that you have power at the white wire, but not watch it off and on with the key. Also, did you verify that you have a continuous ground?
Is the ground to engine ground or separate wire?
The black wire for the solenoid is grounded to the engine. The white wire should get power when the key is in the "on" position.
Great video! The white wire connector (containing the hot and ground wires) that plugs into the shutoff cylinder on my s100 has melted. I’ve searched allover for a new connector, would you have any insight on where I might be able to find one? Thanks!
If you can wait until Thursday I can get you that part number for just the wiring harness section you need. It will not show up on deere.com
That would be great!! Thank you, Sir!
The part you need is AM133284
THANK YOU!!!!
Ok i have a question. My john deere has a fuel shut off valve like the very last one you showed with the mushroomed styled sharp poonted tip.. my question is, all of the other fuel shut off solenoids you tested would pop in and out when turning the key. But the last one u were handling u dljudt pressed it by hand up and down a bunch... i assum though that it, lile the others should be clicking in and out when i turn the key.... it wont do anything.... ive been trying to fix this mower for a konth straight on my weekends. Changed: battery, starter solenoid, spark plug(though all checked out, theyre fairly cheap and times to change regardless.... nxt checked fuel. Changed pump and filter. Been fighting with it all day again, and found your video..... im getting fire and ground to the plug for the fuel shut off solenoid. Solenoids needle is super loose and free moving. Not durty or restricted but it doesnt go in or out when i turn the key.
Yes, the needle should go down when the key is turned to "on"
Check to see if you are getting power to the white wire that plugs into the shut-off solenoid.
Many times its just a connection issue at the plug on the end of the wiring harness is not making contact with the male progs on the shut-off solenoid.
I also like to bench test the solenoid by 12v power to one prong and ground the other prong.
@Mechanical_Mind yes sir I sure did! It is getting power and ground. It was definitely the fuel cut off solenoid. I ground the tip off and it started right up. New solenoid be here in a day or 2
Thanks so much, u saved me!!!!!!
@zard2damoon30 Nice! Just so you know, if your mowers fuel level is higher than that fuel shut off solenoid, its possible, and likely, when you park the mower fuel could leak past the needle valve in the carb and leak into your cylinder and crankcase.
I'd add a manual fuel shut off valve to the fuel line to prevent that.
@@Mechanical_Mind ahhhh, ok thank u so much for the advice.
Mine was. Gas line. Old. Gas line. Blocked fuel
From. Tank. Cut to clean. It had. Shredded. Inside
After years of running gas with ethanol in it the fuel lines could be deteriorating from the inside out. I often need to replace all the fuel line hoses on machines over 6 yrs old or more.
Can't get your test probe far enough into the plug; open a small paper clip and use that to penetrate the plug.
Ok. I have a JD D130. It will start on choke but if I take to choke off it stops. I have replace the fuel pump with after market fuel Solenoid twice. I actually cut the plunger off the solenoid and it worked for a few weeks but now it will not run except on choke and you can not run the mower deck when it choke mode. They are about 15-20 bucks and the John Deere solenoid are $143.00. Any suggestions?
I think your carburetor is bad (dirty, worn, or maybe broken)
Usually that is the issue when it will only run on choke.
@@Mechanical_Mind A guy I know that had not thought of just left my house. The idle jet was clogged so it is all repaired. He mentioned the gaskets in the carburetor are getting worn so I will get a set and he will replace them. Thank you again.
Everything is good but still just cranks any clues or recommendations?
Will it run if you spray some carb cleaner or starter fluid into the airfilter or intake?
@@Mechanical_Mind it does not sadly
@David Willison Ok. I'll help you figure it out. Have you checked to make sure you are getting spark?
If you are getting spark next thing to check would be pull the valve cover off to see if a push rod and rocker arm has gotten loose.
Also, when was the last time it was running? What model mower and engine is it? How many hours are on it?
Hi how are you I'm working on a horn deere 115 it's not a la115 new battery, new after market carb, all I know is there's no fuel coming up to the fuel filter from the tank under the back seat also new fuel pump, and fuel filter can you please help me
If you have no fuel coming from the tank to the filter then you might have a clogged or kinked fuel line.
How do you unclog the line?
I am not getting fuel past the fuel pump. New filter and fuel pump. What else is there to check?
Check to make sure your pick up tube in the fuel tank and the fuel hose from the pick up tube to the fuel pump is not clogged.
Also check to make sure the hose that goes from the fuel pump to the engine (either the top of the valve cover or the engines crank case depending on what engine you have) does not have a crack or cut and is attached firmly.
My zero turn mower is not getting any gas from tank to fuel lines , filter or pump. We ,(Did put new fuel line and pump on it still o pump
Sounds like the pick up tube in the fuel tank is clogged.
It turns over but no start even after starting fluid in carb. Any idea?
Is this a 1 cylinder engine? Make sure you are getting spark.
If you are getting spark and still no start with carb spray, I'd pull the valve cover off to make sure the rocker has not come loose from one of the valves.
Or it could have a stuck valve.
@@Mechanical_Mind it’s a x 585 2 cylinder Kawasaki. Has spark put new plugs in anyway. Checked hose on sending unit it was good. When it was running, I would stop shut it off get a drink or whatever and then it wouldn’t start. It would have to cool down somewhat then it would start this last time. I thought I ran out of gas, but after the fill up, it still wouldn’t start. It started one time with the starting fluid, but that was it that was just cranks over. Thanks for the reply
@@Mechanical_Mind I’ll try that
What about testing a two wire solenoid with 2 same colored wires
What model mower do you have. I'll do my best to help
@@Mechanical_Mind I'm working on a predator 9500 generator. It runs for a couple seconds and shuts off. I don’t think it's the fuel shut solenoid but I want to rule it out. There are two orange wires that go to it. It's getting spark but not as clean as I would like to see and it doesn't run with carb cleaner
Hey man. Sorry for the delayed response. One of the wires has to be the hot wire and one has to be ground. So just test both ways with your multi meter.
Check to make sure your getting good continuous flow of gas to the carb through the fuel line. You may just have a clogged or kinked fuel line.
I'm not to familiar with the fuel line set up on those generators but a kinked fuel line was very common thing I'd see on brand new John Deere mowers.
Had the generator been sitting for a long time without running?
@@Mechanical_Mind thanks for getting back. The 2 wires are orange and connect to 2 red wires. There is also continuity between the 2 orange wires. Neither are grounds. My guess is they are both hot wires but supplying 12 volts to either one doesn't make the fuel solenoid move, I removed it and watched. Plenty of fuel to the carb. Generator runs for a couple of seconds then shuts off. Doesn't keep running with carb cleaner. It doesn't seem like a fuel problem but I would like to just rule out the fuel solenoid
What if your not getting fuel
No fuel going to carb = Clogged or restricted furk line or bad fuel pump or loose or cracked hose going from crank case to fuel pump.
If you are getting fuel to the carb but not into combustion chamber : stuck or faulty fuel shut off valve on the carb or clogged or faulty carb or restriction in the carb.
@@Mechanical_Mind not seeing any go to the fuel filter tried blowing thru gas tank and barley any gas came thru
Mine works because I used a wire to jump it and the plunger moves but it's not getting power from the wire. I think it's my relay
Have you used a test light or multimeter to see if the harness is getting power at the connector end that goes to the fuel shut off switch.
It should have constant power when the key is turn to the "on" position.
(What happens to me frequently is that the harness connection end will be burned or messed up not letting good contact to the fuel shut off switch even though the harness does have power)
@@Mechanical_Mind my brother is coming to check. I don't have a multi meter. It wasn't the relay.
@@Mechanical_MindI’m not getting any power to my plug. Not even to the harness on the other side by the starter. It switches to a yellow wire on the male end of the plug and it just goes up to the relay. So now I’m kinda stumped. Ignition switch possibly?
@ChevyKing311 It could be the ignition switch or relay or solenoid. First make sure the battery is good with a battery tester. Then confirm with a multi meter that you have continuity through the battery connections. And work your way to the ignition switch, relay and solenoid.
If you're not familiar with checking for continuity I did a video on that awhile back. czcams.com/video/lEM7mEWTC18/video.html
So many times it's just something as simple as a slightly loose battery connection or ground wire or bad battery. But all that needs to be confirmed good first. Also confirm the fuse is good. If the fuse is bad and it pops a new fuse instantly then there is a short in the system.
You need to show zoom in I can't see what you are doing!
Hi Charles, here is a better video I did more recently going over the fuel systems and up close footage.
