1. A coil-on-plug (COP) exciter, comprising:
a COP;
a housing configured to be coupled to and positioned at least partially between the COP and an engine;
an electrode core positioned at least partially within the housing, wherein the electrode core has a first end and a second end, and wherein the first end is configured to be coupled to the COP;
an insulator positioned at least partially within the housing, wherein the insulator comprises a non-conductive polymer, and wherein the insulator is configured to provide electrical insulation between the housing and the electrode core;
a seal positioned at least partially within the housing, wherein the seal is configured to isolate pressure between the electrode core and the insulator; and
an electrode tip configured to be coupled to the second end of the electrode core, wherein a voltage is conducted from the COP, through the electrode core, and to the electrode tip, which generates a spark that is configured to energize a first propellant to start the engine.
