I shut off the engine and the ignition is still in the on position
What kind of double-talk is this - you're trying to trick old Gryphon? Heheh...
But I had to read your question twice because, as you know, if you turn your ignition to the off position the motor will stop.
Only use the 'kill' switch as intended, in an emergency.
(And have your battery load-tested ASAP, it's possibly dead.)
You can't just hit the kill switch, then un-kill the switch, then try to start back up.
You've gotta cycle the whole system if it's a new model - the FI, the ECU, countless servos and solenoids...
So shutdown and startup have become very deliberate these days, not unlike rebooting a computer.
Re: Batteries
Not to hijack your thread or anything, but the boys and I are all going with these gel-batteries they've got these days.
They are great and they're inexpensive. I'm talking about just the no-name ones they can get at any shop (GS or whatever the brand is, they're made in China).
Get you one.
Anyway there's my opinion, and good luck to you friend.
