Do you have battery voltage to the key switch from the main fuse holder? Do you hear the fuel solenoid click if you flip key on and off?
Swap the two relays, one is for start, the other is for pto. Appears to be he same number.
Check the one that relays to the start circuit. Does it click when key is turned on? If in doubt as to which one, flip on the pto switch with key on, NOT running. Pto relay should click when switch is pulled. Then check the start relay for input voltage and output when it is on. Likely you will want to replace it. Napa usually will have the relay.
If it is not closing, the starter solenoid does not get voltage.
The relay has a schematic on it. You can check it with an ohm meter.
Relay has to have input voltage to send to the starter solenoid. Do it have voltage to the input terminal? It sounds like the signal voltage is there, which closes the relay, but it has no output.
