Abstract: Implementations of a system for interrupting ignition may include a first spark plug terminal coupled with a first internal contact, the first internal contact extending into a housing; a second spark plug terminal coupled with a second internal contact, the second internal contact extending into the housing; a contactor biased against the first internal contact and the second internal contact; a plunger coupled with a solenoid coupled within the housing; a battery coupled with the solenoid; and a temperature sensor coupled with the battery and the solenoid.

Abstract: A system for interrupting ignition is disclosed. Specific implementations of ignition interrupters may include a first conductive tab configured to couple to a spark plug; a second conductive tab configured to couple to a spark plug wire; a first tab holder coupled with the first conductive tab; a second tab holder coupled with the second conductive tab, where the second conductive tab overlaps with the first conductive tab; a sled positioned perpendicularly to a plane of the first conductive tab and the second conductive tab, the sled coupled between the first conductive tab and the second conductive tab; a first spring coupled to the sled; and a second spring coupled to the sled; where the sled may be configured to move to an open position in the gap between the first conductive tab and the second conductive tab, decompressing the first spring and the second spring.
