Thanks, that's the one I was looking for.

If you put your test meter on ac and put the leads in the crank sensor plug it should read 1 volt or more while cranking the engine. No voltage. Bad crank sensor!!!
1 to 5 VAC while cranking.

This will check your coil.
- Locate the ignition coil positive (+) terminal. Turn the ignition switch to the "run" position. Set the multimeter to the "volts" function. Place the red lead of the multimeter on the positive (+) terminal of the ignition coil. Place the black lead of the multimeter to an engine ground or battery negative (-) terminal. The multimeter should read either six or 12 volts depending on your vehicle specifications. If no voltage at all is present, then there is a problem with the primary ignition circuit to the vehicle that must be corrected.
- Disconnect the positive (+) and negative (-) lead wires from the ignition coil using a combination wrench. Turn the multimeter to the "ohms" function. Place the red lead of the multimeter on the positive (+) terminal of the coil. Place the black lead of the multimeter on the negative (-) terminal of the coil. The multimeter should display a resistance of about 0.4 to 0.6 ohms.
- Move the red lead of the multimeter to the coil output terminal while keeping the black lead on the coil negative (-) terminal. The multimeter should show a resistance of about 5000 to 7200 ohms. If the readings from the primary or secondary windings show a zero "0" or infinity "1" then the coil is bad and must be replaced.
