New Holland WorkMaster 55 loss of power to fuel solenoid

Have a workmaster 55 that I have lost the power to the fuel shut off solenoid causing the tractor to not start. I have checked the fuses under the hood just above the fuel filter, any other ideas?

Hello,
Not certain of similarities, I have a 2017 WM60.

Left front of tractor under hood are relays (which tend to be.an issue). Later on I will look, but I believe there is one labeled "Engine Shut-off" as well as ignition relays.

My tractor has fuses in that location (left front) as well as 8-10 other fuses under the key ignition switch (in a small fuse box).

Here is link to my 'no start' and the fix:

Any other ideas? Here's one. Does your fuel shut off solenoid have a single pink wire? If so then pull the instrument cluster out and look for some relays stuck down in that area. It's tight but you can determine which one has some pink wires in the harness connector. Pull that relay out of the socket and check the wires. One will be hot with key on and one will be the pink wire that goes to the solenoid. I make a jumper wire to connect those terminals together and toss the relay. Problem solved.

Yes sir mine has the single pink wire.

So what's the hold up?

So you are leaving the relay out? The other wires don’t connect to anything just the one ignition hot and the pink?

The other wires. One is a ground wire (the relay coil needs a ground) and the other one (I assume) goes to an operator aggravation module/circuit. The type of thing that monitors seat switch, park brake, PTO, neutral switch type of thing. I'm not totally sure on all of that. I only know I've done this a number of times over the years, and so far not once have I been harassed, sued, shot at, or had any other repercussions sent my way. Tractors are still out there running and people are getting their work done.
