What happens if you don't put firing Order cables right.? spark plugs cables order .

theres no distributor and the firing order for your 3.8 is 1-6-5-4-3-2-the following link shows the coil pack

Check for spark at the plug ( may have coil problem).
If spark is good then do a compression check. Pressure shouldn't be less than 75% of known good cylinders.

Firing order is 1-3-4-2

Are you saying the engine will not crank, or not start ?
If you think two of the cylinders are not getting spark, something may have happened to the coil pack or the crank-cam sensors.
If all 4 plug wires are getting spark, two of them may be on the wrong cylinders. The firing order is not always the same as the plug wire layout.

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,

First,look at the coils see if the towers are numbered.Each coil fires 2 cylinders!
look on intake manifold for fireing order display! The v6 engine fires from one bank across to the other in a straight line example,cylinders 1&2 3&4 and 5&6 at the rear of the engine or farthest right side. 1&2 left side faceing engine 3&4 in the middle. All you need to do is find cylinder # 1 hook up the # 1 wire to the # 1 coil tower to the # 1 plug or cylinder,follow the fireing order 123456,its simple if you cant see coil tower numbers look at another car with same engine that has distributor less ignition.The coil pack for the 4 cylinder gm has plug wire terminals or towers numbered as well.Only in a harder place to see like behind and underneath!

Spark Plug Wires - Removal & Installation

3.5L Engine

1. Before servicing the vehicle, refer to the Precautions Section.
   NOTE Twist the spark plug boot one-half turn in order to release the boot. Pull on the spark plug boot only. Do not pull on the spark plug wire or the wire could be damaged.
2. Remove the intake manifold cover, if required.
3. Disconnect the left side spark plug wires from the spark plugs.
4. Disconnect the left side spark plug wires from the ignition coil.
5. Remove the spark plug wire clips from the Manifold Absolute Pressure (MAP) sensor bracket and the heater inlet and outlet pipe tab.
6. Remove the spark plug wire assembly.
7. If replacing only one plug wire, open the retaining clips and remove the appropriate spark plug wire.
8. Disconnect the right side spark plug wires from the spark plugs.
9. Disconnect the right side spark plugs from the ignition coils.
10. Remove the spark plug wire assembly.
11. If replacing only one plug wire, open the retaining clip and remove the appropriate spark plug wire.

To install:

1. Install the spark plug wire assembly.
2. Connect the right side spark plugs to the ignition coils.
3. Connect the right side spark plug wires to the spark plugs.
4. If replacing only one plug wire, open the retaining clip and install the appropriate spark plug wire.
5. Install the spark plug wire assembly.
6. Connect the left side spark plug wires to the spark plugs.
7. Connect the left side spark plug wires to the ignition coil.
8. Install the spark plug wire clips to the MAP sensor bracket and the heater inlet and outlet pipe tab.
9. If replacing only one plug wire, open the retaining clips and install the appropriate spark plug wire.
10. Install the intake manifold cover, if required.

I really hope help you with this (remember rated this help) Good luck.

Ok here is the meaning of firing order The numbers 1-5-4-2-6-3-7-8 represent the order of wish cylinder the distributor send a spark as it rotates Starting whit cylinder number 1 The distributor will have to rotor on the number 1 cylinder spark plug and the piston on the number 1 cylinder will be at the top So the fuel and air will be compressed and ignited by the spark plug. The next one will be the cylinder number 5 to do the same as the crankshaft and distributor rotate Next will be number 4 then 2 then 6 ? 7 ? 8. You get the idea "10 Degrees" The degrees represent of spark advance You may think gas explode instantly but it actually take a little time So for the explosion has maximum power when the piston reaches the top of the cylinder the distributor send the spark a little ahead of time 10 degrees of revolution is the recommended by the manufacture but that can be adjust buy losing up the distributor clap bolt and manually turn it. In order to adjust that you need a timing gun Than will flash light on the crankshaft pulley (harmonic balancer) and you will see a notch and a series of numbers than represents the timing advance Note If you have not turn the distributor by loosing to button clap bolt I recommend to live it alone and go to you local part store and get the repair manual find the firing order to see wish wire go to wish cylinder Rotate the crack shaft pulley on till the notch is on 0 and see if the distributor rotor is tours cylinder number one. Cars than don?t used distributor do that automatically and constantly adjust the ignition timing by the computer.

3.9L V6 Engine. Engine Firing Order: 1-6-5-4-3-2. Distributor Rotation: Clockwise.............did i guess the right motor? let me know/rate me

your firing order is out you have one lead out
