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
out it was firing off of the cam sensor. Threw in a new crank sensor, and
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
revolution.

I' can't at the moment here the fuel pump but I can here the relay
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
time?

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.

Change the crank sensor
