Default Help, x728 died

OK, so I went out to clear the snow and everything was fine. Tractor started fine, had about 1/3 tank of gas, etc. Cleared the driveway and went out to the street to clean up and tractor started to sputter, almost like it was starving for gas. Finished up in the street and was finishing up our little turn-around and the sputtering got worse and then the tractor died. I thought maybe the gauge was wrong for some reason and added about 5 gallons for gas. Tractor doesn't fire. When I turn on the key, I can hear the fuel pump and the light goes out in the dash indicating fuel pressure, but tractor just turns over with no fire. Any ideas?

Sounds like you ran it out of gas. There's a purge procedure that you need to do. If one of the Kawasaki guys doesn't come along soon, I'll look it up or you can search the site to find it.

Someone just showed that on here how to prime it, there is a screw on top , you loosen it and then turn the key until the gas comes out and then screw the screw back in.

I have run it out of gas before, but never in the winter and never had to do the purge. I will look it up and try that in the morning when I can see. Thanks!

You might have some issues with the fuel pump or fuel pickup inside the tank. Try the easy cheap stuff first.

Yeah there's a short piece of fuel line inside the tank on the fuel pump that likes to loosen up or rupture. If you have gas in the tank that would be my next check. You'll have to remove the fender pan to get at the top of the gas tank and the fuel pump.

Another thing to check is the fuel filter, maybe you got gas with water or crud in it. Obviously also get your electrical connections (I.e. plug wires, coil wires, etc), and check to see if your air filter is wet or dirty. Took alot of ASE courses on auto repair over the years, I always start with the three basics, when engine wont start. Spark, fuel, Air.......is what an egine needs to run.

Unfortunately, I got called into work early this morning so I didn't have a chance to check anything this morning but will this afternoon. One simple question, like I said when I turn on the key I can hear the fuel pump run and then the indicator light on the dash goes out which I was always told indicated that the system had fuel pressure. Where is this pressure measured? Is there a separate pressure switch or is it back pressure on the pump itself? I think I will stop and pickup a fuel filter on the way home. I usually change it in the spring so it's due.

since you are going to change the filter,hold the line from the tank in a can and turn the key.if you don't get fuel flowing out the line it is going to be the rubber hose that is in the tank for the pump.

You should loosen that bleeding screw and take the pressure off the system before removing the filter.

I've shared this sequence before, but here are a couple color photos from my Spring maintenance last year:

Bleed off pressure:


Capture the remaining gas in a small cup (the one I chose was much larger than I needed):


After draining line and filter you can see more than a little dirt in my drain cup:



And for academic exercise, I cut open my filter to see what it was straining out of injectors:



New filter on,


Bleed air as described in scan of Owners Manual. Hopefully start her up.

Jere, thanks for those photos! I did get it started, but it is still stumbling/sputtering under load. I did not get to the dealership for a filter as of yet, so that is my first thing to change. One question about that bleed screw, how far do you back it out? I turned it out about 2-3 turns and cycled the ignition switch several times and then tightened it back down and tried to start it and it still turn over a good 5-10 seconds before it started. Will that screw actually come all the way out (as in fall out) or will it stop before it falls out? I didn't want to take a chance to lose the screw in the snow, so I only turned it about 2-3 turns like I said. About this hose that several have spoken about, how long is it and what size? Is this something I have to get from JD or can I just go to the local auto parts store?

Has anyone ever had to mess with the filter that is in the tank? I'm beginning to think that I may have gotten some bad gas that has caused all of this.

The hose is just a couple of inches long if that...1/8" fuel line.
