Vehicle cranks over fine but will not start. How do you test ignition coil?

Unplug all of the plug wires from the coils, then crank the engine. You should have spark across all of the coil towers. If one doesn't spark, then replace it. If no spark on all of them, remove the ignition control module and take it to your local auto zone to have it tested. If it's ok, replace your crank sensor.
