3rd cylinder spark plug wire bad, but i dont know witch one is the third cylinder and was hoping to get firing order so i replace the right one.Hope you can help. Thanks 07 v6 jeep wrangler 4 w

the firing order is 1-3-4-2. number one cylinder is to the left. hope this helps

Dont tell me you removed all the wires at once without marking them? :O
The best advise for that is, to remove one wire and plug at a time then replace the plug, and connect the wire back in place to avoid mix ups...
I have spec tables for that car, but you need to help me with the model, whats the year model, 92 or 97?

Firing order 1-3-7-2-6-5-4-8 --------- front ' 1 2 3 4 ' of ' 'distributorless ignition vehicle ' 5 6 7 8

what size engine.. do you have new wires... you need the number off the wires so you can put them in properly... because each wire will go to specific cylinder and place on the distributor

GET A PIECE PAPER DRAW A LARGE CIRCLE TOP UPPER HALF CIRCLE LEFT TO RIGHT WRITE NUMBERS 1 AND 3 BOTTOM HALF CIRCLE LEFT TO RIGHT RIGHT NUMBERS 2 AND 4 THAT YOUR DISTRIBUTOR SPARK PLUGS WIRES LOCATION.STANDING ON SIDE OF ENGINE WHERE DISTRIBUTOR IS LOOKING DOWN AT DISTRIBUTOR 1 AND 3 FIRST TWO SPARK PLUGS TERMINALS NEXT TO ENGINE. AND 2 AND 4 SPARK PLUGS TERMINAL ON CAP FACING YOU. THIS IS CYLINDERS LOCATIONS STANDING IN FRONT OF ENGINE.RUN WIRES FROM DISTRIBUTOR CAP TO PLUGS TO THE ENGINE SPARK PLUGS.

Looking at the engine, right side,last injector closest to the fire wall. This is number 7 cylinder/injector. The same side runs as follows; 1,3,5,7 and are the odd cylinders located on this side, and 2,4,6,8 are on the left side, #8 is closest to the firewall. In case you need to know, the firing order is ; 1,8,4,3,6,5,7,2. Hope this helps you.

Hope this helps. The ignition coil:

• changes low-voltage pulses from the PCM to high-voltage pulses.
• fires 2 spark plugs simultaneously.
• has 3 transformers.
  • One transformer fires the spark plugs for cylinders 1 and 5
  • One transformer fires the spark plugs for cylinders 2 and 6
  • One transformer fires the spark plugs for cylinders 3 and 4

Spark plug wires:

• carry high-voltage pulses from the ignition coil to the spark plugs.

The spark plugs:

• change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.

The firing order is 1-4-2-5-3-6.

The cylinder order is 1,2,3 (rear row, left-to-right) and then 4,5,6 (front row, left-to-right).
When replacing spark plug wires or plugs, it's very helpful to do one at a time to avoid connecting them incorrectly.
Hope this helps, Sherwin

The third cylinder is the third spark plug wire from the passenger side of the car. An easy way to tell if this is the cylinder that is misfiring is to pull up the spark plug wire using insulated pliers with the car running. If there is no change in idle speed then that's the dead cylinder. If when you pull out the spark plug wire you see sparks shooting all over from it (a very common problem) then you need a tune-up.

put the cylinder one on TDC
pull the cap off and look at witch one the rotor is on..
then going clock wise here are the firing orders depending on which engine you have...
4 cylinder 1-3-4-2/ 6 cylinder 1-6-5-4-3-2/
8 cylinder 1-8-4-3-6-5-7-2
