Ignition System Do’s and Don’ts

Your first tool for diagnosing an ignition issue is your eyes. Spend some time inspecting the coil’s connector, boot and the spark plug. Often the cause of an ignition system problem will present itself.

Causes of No-Spark Conditions

A no-spark condition could be the result of communication errors or missing data from a dead module.

Ignition Coil Failures

There are many ways an ignition coil can fail. Here’s what you need to know.

Secondary Ignition Diagnostics

There’s more to ignition science than looking for the classic quarter-inch long “hot blue spark” jumping from coil secondary to ground.

Diagnosing Crankshaft and Camshaft Signals

It’s more important than ever to understand how the crankshaft and camshaft sensors function in both the ignition control and fuel injection systems.

Scoping and Interpreting Secondary Ignition Waveforms

The secret to being able to capture and analyze secondary ignition waveforms is understanding what is happening in the coil and at the spark plug, and how the scope measures and graphs the voltages and ignition event.
