The failure to start is almost certainly caused by bad or old gasoline, or a bad safety switch. For guidance, see https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Lawn-Mower/79-311--WVRIMjFLNDYg/Husqvarna-Lawn-mower-won-t-start. For a wiring diagram, you'd have to ask Husqvarna. (Use the contact information here--https://www.contacthelp.com/huaqvarna/customer-service.)
