Cub RZT SX Cranks but won't start, no power to fuel solenoid.

[TJL001]

I have a cub cadet RZT SX 46

It's pretty much a 0 turn with a steering wheel. 23 hp carbureted kohler. The machine has that computer push button start.
I have no power to the fuel solenoid when cranking the engine over. I don't pretend to understand these computer push button switched but I have to wonder if that $200 switch is my problem. Any help is much appeciated.

Welcome. Could post the product number from below the seat? I've not had that issue. The only issue that I've had with those switches were on the tractors and were for a no crank.
Prior to this, if you set the brake- would it crank w/o being on the seat?

Here is the product model number 17RRCBYN010, Serial number 1J048H10074.
It doesn't crank with the park brake on. I don't know about prior, this is a customer of mine who had it worked somewhere else.

Hmm, I don't have a manual. There were bulletins regarding some switch changes that don't apply to RCC's though.

What is known: Both seat switch functions are shown as NC. The brake switch is the usual NO/NC. It didn't show a PTO relay in the schematic, but it won't be the first time that it is missed. It's that typical little skinny one in console I'd think if it has one.

Off the top of my head, if it fires w/ a burst of carb spray when cranked- we know the ignition isn't also killed. This to me would more likely indicate a module more so that if it thought the operator came off the seat. As always I'd cover grounds and connectors. I'll be interested in what you find, so keep us posted.

To add: This very likely has a brake style interlock switch for reverse sensing also.
