LS XU 6168 No Start

[BulFrog]

Having some issues with forward and reverse Lever. Yesterday it started in reverse, had code F04 106 flashing and was low on power.
Parked and let set overnight. Then today No start in any position of lever.
Can anyone HELP.

Neutral safety switch? Or its equivalent sensor in the drive circuit?

 

[BulFrog]

Thanks for you help.
I will see what I can find.

Is your warning light on? Solid Red? On my xr4150 that code/light combo indicates either P0106 - intake manifold absolute pressure sensor signal drift fault, or P0107 - intake manifold absolute pressure sensor signal low fault.

warning light was on when tractor was running.
but not with just switch turning today. Undone battery to set over night.

Ordered Service Manual today, maybe this will help.

Is the battery fully charged? ECMs can get really wonky when voltage drops or fluctuates.

Sorry for delay. LS is back running. Bad neutral switch, with a blown horn relay fuse that was messing with voltage.
