I just had a bad crank sensor on a '00 Durango. Crank/no fire, and no
codes. The coil was only firing once per revolution of the engine - turns

it lit right up.
Check for spark at the #1 plug. If no spark there, check for spark at the
coil (remove coil wire from distributor, put it on a plug, and ground plug
to engine). If the crank sensor is good, you should see multiple sparks per

unfortunately there to much background noise and I'm to deaf to hear it, but
I do believe its working. I pulled the wires coming into the coil off and
there's no power to the coil should this be hot only when running or all the
There's power to pin #1 of the coil connector only when the ASD relay is
engaged - which means only when the ignition switch is on, and the PCM sees
input from the crank and/or cam sensors.
Now - check for spark from the coil like I suggested.
Checked the coil there is no spark at either #1 plug or at the coil itself.
I checked the wires leading to the coil and the connection the seem good
even though I have not tested them with a multi meter to be sure.
