What the hell are you asking??? Seems you don't know what you're talking about at all or have had WAY too much coffee and can't explain it well... or both... or it's just me (I'm no good with wiring, as anyone here... last person who should be giving any advice on it.
).
A problem with the wiring up to the switch is going screw with a LOT more things than just the igniter... and much more directly. Have you checked for diagnostic codes? What other problems are you having? Have you tested the power at the ECU to make sure all the right terminals have the right amount of power at the right time?
