Mazda Protege, 1999, 1.8L 125,000 miles. Car is cranking and cranking but not firing up. I noticed the ignition coils were not producing sparks at all while trying to start, and have also had random misfires in the past. Is there a sensor to tell the coil packs to fire, or just replace them? Help!

The crank angle sensor triggers the coils and cause them to fire. However this isn't the only part that is involved with the ignition system. Using a voltmeter verify that you have power to the coils. If you have power to the coils test them with an ohmmeter and see if the resistance is within specs. If there is no power to the coils then check wiring to the coils. You can also check the crank sensor with the ohmmeter to see if it is within specs.
