What would cause no fire on two ports on coil pack

#2 cylinder misfire. Plug, wire, or coil pack. One of them is bad. My guess is the coil pack. Pull the wire off the coil, lay it on top the coil close to the #2 port. Start the van. You should see the coil throwing an arc to the plug wire. No arc replace the coil. If you have arc, then replace the plug and wire. I would do all of them.

If it has `coil on plug' ignition,it's probably a coil.If it has coil packs, it's probably a coil pack. don-ohio (:^)

The coils these days are operated by the ecu's and faulty coils can cause damage to the ecu if not replaced asap, the coils in the coil pack are charged by a current and then the voltage increases from 12volts to the amount needed to jump across the spark plug gap(alot) not dangerous unless you have a heart condition.

not likely, since the engine module also fire the plug across from the #2 cylinder on the coil pack. check for spark directly at the coil, if none is found ,then most likely a bad coil pack.

The spark issue is caused by the coil packs, this will cause the bogging down, the smoke could be from several issues beside the spark, can't tell till you repair the coil packs

I would suspect a head gasket or head problem.. the catalytic converter being plugged causes heat build up in the engine and overheating in the engine can cause failure of the head hasket or head itself. The reason your cylinders are misfiring could be water leaking from a water port in the head and into the cylinder which would cause the cylinder not to fire..there might be some steamy vapor coming coming out of the exhaust if that is happening

Need to replace the coil pack. If there is a problem with the ignition module, then other coil pack would not work.

Have you replaced the plug wires? If they have too much resistance they can cause the coil to fail.

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

Attach the spark plug wires in the firing order. The firing order should be in your owner's manual. It also might have a diagram next to your ignition coil pack. The ports on the coil pack are shown by the diagram.
