Spark plug wire sequence foor a 3.1

1. Connect the distributor's B+ (battery) terminal to a switched 12-volt source, such as the ignition switch.

2. Connect the distributor's tach terminal to the tachometer signal wire, if you have a tachometer.

3. Connect the distributor's ground wire to a good engine ground.

4. Connect the distributor's #1 spark plug wire to the #1 spark plug on the engine. The #1 spark plug is usually located on the driver's side front cylinder.

5. Connect the remaining spark plug wires in firing order sequence to the distributor cap terminals. The firing order for a Buick 455 engine is 1-8-4-3-6-5-7-2.

6. Install the distributor cap and rotor.

On your smart phones browser put in Make, model, 3.2 engine firing order. It will bring back the firing order sequence and from that you should be able to figure out the wiring sequence and which wire goes to which plug. All you need to know is where the number one plug is on the coil pack.

Engine knocking usually cause by wrong connection of Spark plug wire sometimes called High Tension Wire. Check the manual and make sure the firing sequence of wire connection is properly connected to the distributor cap according to the manual. Ex is: 1-4-3-2 for 4 cyl engine.
For 6 cyl engine, 1-6-5-4-3-2 or 1-6-2-5-3-4. when in doubt, ask mechanic help. If wires firing sequence are correct, then you have to check the camshaft bearing or camshaft itself. Hope this help.

Firing order for a 305 is 1-8-4-3-6-5-7-2. The distributor turns counter clockwise and #1 should be the 5 o'clock position looking down at the top of the distributor.

You may have got the spark plug wires out of sequence.
Reseat the coil wire going to the center of the distributor cap Check the spark plug wires at the distributor against the firing order as follows:
The spark plug firing order is 1 - 4 - 2 - 5 - 3 - 6 The distributor rotor turns CLOCKWISE The engine cylinders / spark plugs are numbered :
firewall 3 - 6 2 - 5 1 - 4 front

Yes do put it on in numbered sequence,but check on the cylinder head where piston 1 is.usually it`s by the timing belt side.

Changing the spark plugs is a pretty easy task. The spark plugs run along both sides of the engine (if its a V block) , 1 per cylinder. You can easily identify them by the plug wires running to them from the distributor. Pop off each plug wire, (1 at a time) and replace the spark plug. Once you have replaced the plug, replace the plug wire. This ensures that you dont mess up the sequence of the wires which determines which cylinder fires at what time in the cycle. VERY important not to mess up the sequence. If you should happen to get the wires mixed up, look online for the firing sequence for your vehicle and engine.

Hi,
I don't know your engine size, but the link below is a picture of the GM small block firing order with distributor.
The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
