2000 Dodge Caravan 3.3L V6 spark plug wire diagram from engine to coil pack

If one of your ignition coils on the coil pack has gone out, that would affect two cylinders, and you would only have 4 cylinders still functioning. Those two cylinders would not have spark, well, actually a jolt of high voltage current, on the wires going to the spark plugs.

Make sure the mechanic replaced your head bolts. Do not re use old head bolts. Then verify your compression at each cylinder, then you can move on to other possibilities. If you have good pressure and the torque sequence was followed, then check the basics; spark plugs, wires, and your coil pack. (I think you have a coil pack, not a cap) My money is on your coil pack. There is many things it could be, but this gives you a starting point.

the dark green with orange wire is the only one that should have power. The other three are grounded by the PCM.

Check your coil/coil packs if equipped, also make sure plug wires aren't damaged i.e. perform a resistance test.

the coil pack should b labled if not then plug is at bottom and the top wire port to the back of engine compartment is #3 then 1-5 these plugs are located on firewall side of engine (thing to remeber the clyinder heads are off set from oneanother the one that sit to the front of engine is odd side 1,3,5,7 other 2,4,6,8)the lower ports are 2-4-6 and go in front of radiator.

here you go.

Hi, Replace the coil and wires. This should fix it. Replace all the wires too. Good luck.

This is a quick explanation:

1996 Dodge Caravan
3.3 liter




The big rectangles are referencing the engine, the cylinder associated to it's "firing" are the colored circles, and the are also the location of the spark plugs....the smaller lego-looking block is your coil pack. The spark plug wires run from the coil pack to the spark plug on the engine. The wires match 1 to1 or black to black...and so on....

When these are matched to each cylinder/spark plug and it's wire leading to the matching coil pack position, this is it's "firing order". If one of the wires is "crossed" meaning, not 1 going to 1, then the engine will "miss-fire".

It means that the number 2 cylinder (passenger front of the engine) is not working. Whether its spark, fuel, or mechanical. The first thing you can check is if there is spark to the cylinder. With the engine running remove the spark plug wire from the number 2 spark plug. Listen or look for spark out of the plug wire. If there isn't than you can check for spark out of the coil pack. Do this with a test light or spark tester. With the engine off remove the number 2 spark plug wire from the coil pack. With the spark tester installed or the test light hooked to ground and placed on the #2 coil post have some body crank the engine over. If ther4e is no spark that you might have a bad coil pack. If there is spark than possibly the plug wire is bad.

You should not drive it with a misfire as you could ruin the catalytic converter which is very expensive to replace.

maybe it is the spark plugs or spark plug wires. or it is the distributor cap and rotor. the coil just provides the spark. but you can have it tested at a part store.
