firing order and coil pack assignment

My info shows coil on plug ignition, no coil pack. Each spark plug has it's own coil. Your engine has odd and even numbered banks. driver side bank, from front to back, 1 3 5. Passenger side bank, front to back, 2 4 6. In the diagram, the wire colors for ignition coils, 1 2 3. Number 1 ignition coil goes on spark plug for number 1 cylinder and so on.

Thank you Jeff. Clarified my problem. Oilyspill, my engine does NOT have a coil per cylinder

My bad, that is what my database showed. I even looked up ignition coil, online parts book. Showed coil on plug type coil. Napa showed the same type coil. I usually trust Napa. My bad.

For Chrysler 3.7L V6 engines: (mine just happens to be in a 2011 Jeep Liberty) CYLINDER NUMBERS standing at the front and facing the motor... right side front to back 1,3,5 (note they are all odd numbers in order) left side front to back 2,4,6 (note they are all even numbers in order) There is no need for spark plug wires on the right side of the engine. This motor has 3 coils and they snap directly on top of the spark plugs 1,3,5 on the right side. The left side does not have their own coils. Three spark plug wires run from the left and snap on to the side of one of the three coils that are on the right side. TO MAKE IT EASY, DO THESE TWO THINGS BEFORE YOU START WORKING OR BEFORE YOU READ ANY FURTHER... (I wish I would have done this before I accidentally mixed up my spark plug wires) ON THE RIGHT SIDE DO THIS: - THE FRONT COIL, WRITE A (1) ON TOP OF IT & WRITE A (4) ON THE SIDE OF IT AND A (4) ON THE END OF THAT PLUG WIRE. - THE MIDDLE COIL, WRITE A (3) ON TOP OF IT & WRITE A (6) ON THE SIDE OF IT AND A (6) ON THE END OF THAT PLUG WIRE. - THE BACK COIL, WRITE A (5) ON TOP OF IT & WRITE A (2) ON THE SIDE OF IT AND A (2) ON THE END OF THAT PLUG WIRE. ON THE LEFT SIDE DO THIS: - AT THE FRONT SPARK PLUG, WRITE A (2) ON THE MOTOR NEXT TO IT AND A (2) ON THE END OF THAT PLUG WIRE. - AT THE MIDDLE SPARK PLUG, WRITE A (4) ON THE MOTOR NEXT TO IT AND A (4) ON THE END OF THAT PLUG WIRE. - AT THE BACK SPARK PLUG, WRITE A (6) ON THE MOTOR NEXT TO IT AND A (6) ON THE END OF THAT PLUG WIRE. SPARK PLUG WIRES, which wire goes where? It's easy once you know the firing order of this 3.7L engine. FIRING ORDER 1,6,5,4,3,2 First take the firing order and split it down the middle, making two halves (165) and (432) Second stack the numbers. In other words pair up the first number of each half, then the second numbers to each other, then the third ones. So you wind up with these three pairs: 1-4, 6-3, 5-2. These pairs show which spark plug wire goes to which coil.

Less technical and less detailed instructions listed below: (front spark plug wire goes to back coil) or wire from cylinder 2-to-5 cylinder coil pack (as listed in pairs above) (middle spark plug wire goes to front coil) or wire from cylinder 4-to-1 cylinder coil pack (as listed in pairs above) (back spark plug wire goes to middle coil) or wire from cylinder 6-to-3 cylinder coil pack (as listed in pairs above)
