Hi springstchick

A no spark problem has many possibilities, the key is to narrow it down to which particular circuit is at fault. This requires testing of engine components using a DVOM in conjunction with using wiring diagrams to test for example cam sensors ( if any), coils, wire connections, ignition module, pickup coil (on some models), PCM's, ignition switch, fuses, spark plug wires, spark plugs, battery, cap & rotor ( if applicable). All these work in tandem to provide the necessary high voltage for the engine to work.
