What does it mean when your ignition coil is not working?
CASE 1: You got spark on all of the spark plug wires. This is the correct test result and it tells you that the spark plug wires, distributor cap and rotor, ignition module, and ignition coil are working. These components are NOT the cause of your no start condition.
When does an ignition module need to be replaced?
If the light blinks, the module is good. If the light is blank or constant, the module is bad. Before you attempt to replace the control module, you must rule out other ignition system components. The module is expensive and replacing it is a laborious process. Check the ignition coil for a spark.
Where is the ignition module in a car?
The module receives a signal from a sensor inside the distributor. The signal is then used to fire the ignition coil creating the energy for the spark plugs. The ignition module may be located inside the distributor, on the distributor housing, or mounted to the side of the engine compartment.
How to test the GM distributor mounted ignition module?
By testing for spark directly on the distributor cap towers that feed those spark plug wires. OK, this is what you need to do: Remove the spark plug wire that did not spark from its tower on the distributor cap and place the spark tester directly on the tower.
When did Pontiac stop using transistorized ignition system?
Many electronic conversion kits are available. Since the 1960s, Pontiac has used various ignition systems that were electronically triggered. Its Transistorized Ignition was eventually replaced by the Unitized Ignition System in the early 1970s.
When did Pontiac start using high energy ignition?
Don’t let that appearance mislead you, however. This unit functioned perfectly after a thorough cleanup and proper lubrication. General Motors introduced its high energy ignition (HEI) system in 1974 and Pontiac used it on a number of its V-8s beginning in the middle of the model year.

Do you need an ignition box for a Pontiac V-8?
MSD offers a second Pro-Billet distributor for the Pontiac V-8 in its Ready-To-Run line. It includes an internal electronic control module and doesn’t require a separate ignition control box for normal operation, but it’s certainly compatible with it. A vacuum advance canister makes it an excellent choice for street applications.
What makes a Nissan 3.0L engine not start?
Without spark, the engine will crank but no start. The ignition system of the Nissan vehicles covered by this article use either distributor type system or a COP (Coil-On-Plug) ignition coil system. In a COP ignition coil system, each cylinder has its own ignition coil; thus eliminating the distributor entirely.
Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.
What kind of ignition system does a Nissan use?
The ignition system of the Nissan vehicles covered by this article use either distributor type system or a COP (Coil-On-Plug) ignition coil system. In a COP ignition coil system, each cylinder has its own ignition coil; thus eliminating the distributor entirely.
What to do if there is no spark at the ignition coil?
Check for voltage output at the ignition coil. Disconnect the ignition coil wire from the distributor and install the spark tester to the wire and ground the tester to the engine. Crank the engine for a few seconds. If there’s spark, the problem is with the distributor cap or rotor.

Why is there no spark at the coil axle?
If there’s no voltage, check the wire between the ignition switch and the coil and, if necessary, the switch itself. If there’s voltage, the problem may be with the pickup unit. If the pickup is good, then the problem may be with the ignition control module.
