Need to know the firing order to the coilpac how the plug wires go in

When you replace plug wires, you need to know the firing order or be careful not to mix the wires up... If you get the firing order wrong, the engine may not start or if it does start, will run very badly.

FIRING ORDERS

Print
See Figures 1 and 2
To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.

If your trying to change spark plugs remove one wire from a plug, replace that plug, reinstall the wire onto that plug and move on to the next plug. You don;t need to worry about firing order unless you plan on changing the wires or the cap and rotor. Even if you where to change the wires if you did them one at a time than the new ones would be in the exact same place as the old ones and there is nothing to worry about,

You need to determin which direction the rotor button turns when the engine is running. Take the cap off and get someone to bump the starter . Watch the rotor. If it turns counter clockwise the fireing order will follow its order counter clockwise on the distributer .In other words # 1 wire on the distributer goes to # 1 spark plug. Then the next wire counting counterclockwise goes to # 3 plug . Follow the firing around the distributer for all the wires. counter clockwise is the oppisit to the rotation of the hands on a clock .

Misfire could be caused from bad plugs, plug wires, coils, injectors or fuel pressure. How many miles on the plugs and wires? Were the plugs gapped correctly? Time for a tune-up? You can get the parts you need as well as firing order and diagragm to show which cylinder is 1, 2, 3, 4,5 and 6 at Auto Zone.

Several engines here:
* 1.8L (B18B1 and B18C1) Engines Firing order: 1-3-4-2 Distributor rotation: Clockwise



* 2.2L (F22B1) and 2.3L (F23A1) Engines Firing order: 1-3-4-2 Distributor rotation: Clockwise



* 2.5L (G25A4) Engine Firing order: 1-2-4-5-3 Distributorless ignition system



* 3.0L (C30A1) Engine Firing order: 1-4-2-5-3-6 Distributorless ignition system (one coil per cylinder)



* 3.0L (J30A1) Engine Firing order: 1-4-2-5-3-6 Distributor rotation: Counterclockwise



* 3.2L and 3.5L Engines Firing order: 1-2-3-4-5-6 Distributorless Ignition System




Hope helped with this (remember rated this help) Good luck.

go for the cheaper option replace the crankshaft sensor firstly.good luck.

One wire should be power with the key on and the other 3 should be pulsing ground from the computer. Check the crank sensor. Next to the crank pulley.
