Troubleshooting Cat 3126 MUI no hot start issue Challenger 55 Tractor. Maybe I can save you some trouble when you're trying to figure out why your Cat 3126 MUI engine doesn't want to start when its hot but will run fine after you use starting fluid to get it started. Troubleshooting is the most frustrating part of the repair and finding any help on the issue was very difficult for me.
