stupid van!!!

[jpb53]

Did you ck the wire for continuity?

[STEVE952]

could it be that the dk bule w/ tan stripe wire has been spliced prior to my problems. When I first got this van it wouldn't start at all... and a mechanic told me to splice that bl/tan wire at the connector to the coil pack and run a hot wire from it to the pos. battery...it fired right up... but now I have a misfire on 2 & 5. And when I move that wire around the car will die.

Sure could. I would find the splice, remove it, then solder the wires back together.

One driver for each coil in the pack. You test them at the coil pack harness connector using a test light connected to the + battery connection. The connector has 4 contacts on it. 3 are the driver circuit outputs from the PCM. DON'T TEST THAT 4th CONTACT. It has a dark green/orange wire attached. You can fry the PCM. As you crank the engine to test the drivers the test light should blink on and off. If one or more won't blink, the PCM is bad. If none of the 3 blink, the problem is likely in the cam/crank ASD circuit. You should only see that if the van won't start. Not your headache.

You should see 4 wires at the back of the coil pack connector:

dark blue with tan stripe wire - driver for coil firing cylinders 2 and 5 (if your PCM is bad you won't get a blink here)
gray with red stripe wire - driver for coil firing cylinders 1 and 4
red with yellow stripe wire - driver for coil firing cylinders 3 and 6
dark green with orange stripe wire from ASD relay - DON"T TOUCH

Great test! With the "new/used" pcm, test light flashed on all 3 drivers. In typical Mopar fashion, it still has a miss but hasn't thrown any codes yet. I'll drive it some more tomorrow and see.
