2004 JD X485
JD X485. Power to fuel pump and instrument cluster. No power to starter.

I don’t think the safety switches cut power to fuel pump or instrument cluster but they do affect the start circuit and ignition circuits. I would start by verifying operation of seat switch, neutral switch and PTO switch. I believe they all tie into the start and or ignition circuits.
If memory is correct Deere also had some circuit boards in the start circuit on that model.

I’ve checked seat switch, but have only found 1 switch that controls rto. I replaced the pro switch. I checked and cleaned relays. I guess it’s in the circuit board. Looks difficult to test. Thanks for your help

Also, can’t find a switch for brake.

Welcome to TBN
What is rto? What is pro switch ? Maybe typo's, but maybe something else.

Sorry, for typos, RTO switch is reverse pto, also , checked the neutral switch under pedals. I accustomed to seeing a brake switch, but can’t seem to find it.

I believe TM2023 is the Deere technical service manual for the X485. Deere typically have very detailed wiring diagram and diagnostic instructions. My suggestion is to invest in the manual.
