XT2 SLX50 will not start
 

Have a 2019 XT2 SLX50 with the 679CC EFI engine. Model # is 13AZA2CZ010

Serviced it a month ago and mowed afterward. Everything was fine. Ran like it always has. As I was having a hip replacement, I had everything ready for the Wife to mow while I recuperated. She goes out a week later and it will not start. Turns over as always. Finally got it into my shop and it has no spark. Checked all the switches and they seem fine.
Cannot find anything that may be obviously wrong.

Any help would be appreciated, as I cannot even load it to take it to be repaired. I can hobble around in the shop and check things on it.

Thanks,
DH

I looked online but can't find a schematic for your machine, sorry.

is this the push button start ? if so they don't like dampness , had 1 that i took the switch out and into my house to dry it out then it worked fine

Thanks. I will try that.

Hows the hip , My wife had hers done 4 months ago , slowly improving

p.s. know nothing about your mower (lol)

not to be smart, hope a mouse didn,t do a little nibbleling. just because you said just recently serviced. when your good test light and multimeter.

I have the same problem with my EFI MTD Cub in name only. I purchased a used Husqvarna 52 in garden tractor with a locking rear axle. Paid $200 for it, replaced the carb because the fuel had set in the mower for 3 years, changed the plugs, all the filters and replaced the blade clutch. I adjusted the valves and the choke cable. I started using the Husqvarna so that freed the Cub up for me to tare into. Today I removed a lot of stuff, fuel tank, dash, wiring harness engine cover, etc. what I found is on the throttle body is a device that looks like a throttle position sensor, which it is, but it is also an engine control computer
What I discovered was the plug of wires on the engine computer did not appear to be fully seated. I removed the plug and i looked at the connector and it appeared fine so I plugged it back in and made sure it was fully seated. I assembled everything else except the engine cover and I pushed the start button and it roared to life. Drove it around the field and it never quit . Stopped and started the engine a dozen times or more and it started every time. This engine does not have a magneto ignition, it uses battery voltage to create spark. There is a position sensor off of the flywheel and there are a bunch of teeth that this sensor counts. All of the wires from both coils the sensor, the O2 sensor and the engine temperature as well as the injector go to this engine computer/ TPS. It is a crying shame that MTD / Cub will not provide shop manuals for service on these things. The Husqvarna I bought for $200 is a 2015 model and I love it. Much better design than this overpriced MTD. I hope this helps and you can get yours running.
