12V IGNition is all the FSS needs to let the IP run. Can't be much simpler than that.

Don't need no stinkin' HPOP or FICM!

Exactly why I choose this truck and engine. Basic and simple to fix while out in the bush. I’m wiring the fss to a backup toggle in case there is ever a wiring issue I can hit the toggle and jump the starter solenoid/or push start the truck. I’m trying to think up an emergency bypass to the fss. FYI I have a emergency fuel shutoff in a ball valve on the main fuel line in case of run away issues
