You can bypass a capacitor-discharge ignition (CDI) box temporarily for troubleshooting purposes. Since a CDI box transmits voltage from the pick-up coil in the stator to the ignition coil and does not generate continuous sparks, it cannot store enough voltage to keep the engine running.
Msmoke: Thank you so much for the information you have provided regarding bypassing the coil and ignition module on a 22R. I assume that what you are calling the "spark plug wire" is a black heavily insulated wire identical in appearance to the wires running from the distributor to the 4 spark plugs that connects from the distributor cap to the coil, and that what you are calling the ...
Ignition coils are an electronic engine management component that are a part of the vehicle’s ignition system. The ignition coil functions as an induction coil that converts the vehicle’s 12 volts into the several thousand that are required to jump the spark plug gap and ignite the engine’s air-fuel mixture. Some ignition systems will use ...
Here is a photo of the ignition coil. It is in the engine compartment against the fire wall. if you find the distributor with 4 wires going to the spark plugs, follow the distributor center wire ...

The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit. The key concept of the ignition coil is that it is a step up transformer. It actually has two coils inside.
Hot-wiring is the process of bypassing an automobile's ignition interlock and thus starting it without the key. It is often utilized during a vehicle theft. However, a legitimate vehicle owner who has lost their vehicle key may also implement this process.
Diagram of a simple circuit with an inductance L and a flyback diode D. The resistor R represents the resistance of the inductor's windings A flyback diode is a diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters. This diode is known by many other names, such as kickback diode, snubber diode, commutating diode, freewheeling diode, suppression diode, clamp diode, or catch diode.
High energy ignition, also known as H.E.I., is an electronic ignition system designed by the Delco-Remy Division of General Motors, and introduced on some GM vehicles in 1974, including the Camaro Z28 Special High Performance (with 3123 units factory installed) and 1974 Buick Century Gran Sport Stage 1 (distributor code 1112521). It was used on all engines from 1975 through the mid-1980s. There were many design variations over the years, and provisions for computer controls were added for some applications starting in the late 1970s. A predecessor system was optional on Pontiacs as "code 704 UPC K65 unitized ignition system" for the 1972 and 1973 model years. HEI is characterized by the incorporation of the ignition coil into the distributor cap for most applications. The system consists of a control module and a magnetic pickup mounted in the distributor. This eliminates ignition points and the coil wire. The control module performs the same function as the breaker points in a points and condenser system.
