Chrysler 300M Special: My spark plugs arent getting a spark.

This answer was rated:

My spark plugs aren't getting a spark. I took out a coil pack I attached the wire to the inside and held it close to the engine ground point and car turned over no spark did this to two others and no spark. My car turns over fine my fuel pressure is fine my cam crank and throttle sensor is fine changed pcm and replaced the battery but car won't. Start I have a 2002 chrysr 300m special

What engine? Is this coil on plug? Is the check engine light remaining on?

I have a 3.5 and my engine light pops on then goes off
Do you have a scan tool or a way to retrieve that code or codes?
Is this coil on plug?
Customer: replied 4 years ago.
I don't have a way to get the codes right now. The coils are on the plug
Ok, with the key on run, do you have voltage going to all of the coils? The dark green/light green wires.
If nothing check Fuse S, fuse N and fuse W in the pdc.

I just checked my codes none appeared and my engine light is on and it blinked 10 times. We are having a pretty bad storm I will check fuses tomorrow.

Ok I was able to test my coils with a voltmeter they were fine and the fuses and relays.

Do you have a code reader or a scan tool?

Customer: replied 4 years ago.
I have a code reader but no codes came up

Refer to this test procedure, click here and perform these tests. Hold on one moment while I find a wiring diagram.

Ok here are 2 wiring diagrams, click here.


The 2nd is 3 combinned and the other shows the ign coil drivers. They call ign #1 driver pin K19 in the test, but I believe it is actually K91 in the diagram.
