It's possible the wiring harness is compromised. I'd want to see voltage at the coils when the ignition is on so you know they are able to provide spark. The chain required to allow the ignition to see power is the one I'd want to verify. The master relay is typically the one that is powered by the kill switch.... same way an emergency off switch works. If you lose power to the coil of the master relay, you can't close the contacts and get power to the coils. I'd expect the same circuit would power the fuel pump, but the instruments would be on a different circuit.
What becomes energized, when you turn the key to the 'on' position? What do you think SHOULD become energized at that time?
This is exactly what I don't know and am hoping someone can help me figure out. I am terrible with electronics and am not sure what SHOULD be getting power or the best way to test what is IS getting power. I know that when the ignition is on, the fuel pump doesn't run, but when the kill switch is on, it does. So that, to me, says that the ignition and the kill switch are both working.
I think that I can also safely say that the starter switch, relay, and Motor are all working as well since the switch fires the relay which sends power to the motor which turns over the engine.
That's about as far as I know what to do. I already did all the troubleshooting and diagnostic stuff I could find in the manual, but it certainly doesn't have everything nor does it provide any big picture understanding to someone like myself who is somewhat lacking.
So, any tips on what I should test and how I should test it?
I'll be pulling plugs to see if they spark in just a moment, but then, if they don't, how do I test if the coils are good?
