You dont say what engine you have but this is the most commmon. The cylinders are numbered 1-2-3-4 front to back on the pass. side and 5-6-7-8 on the drivers. Pull the #1 plug and bump the starter and when you feel the piston come up on compression, turn the engine slowly intil the timing mark is on top deae center. Pull the cap and where the rotor is pointing is where #1 wire goes. Then contimue with the wires. 1-5-4-2-6-3-7-8 in a counterclockwise direction. #1 wire should be just to the right of center in the back when viewed from the front of the engine unless it has been changed.

Check firing order
The most common reason for a vehicle to run rough when it is cold is bad spark plugs or bad spark plug wires. Change the spark plugs and spark plug wires.
Few things. Check first of all the spark plugs make sure they don't need to be changed. Then it if they are in good condition that is not burnt or covered in oil/grease (if so that might be the problem change them) check the spark plug wires and make sure the spark gets to the end. But if the spark does show but it still doesn't ignite its most likely the timing. If no spark go to the rotor and make sure that's its in a good condition. Most likely its the sparkplugs or the wires less likely the distributor. Check them in any order you preffer. But my guess it would be the spark plugs
The ignition (spark plugs, wires, cap and rotor) may have been wet or the firing order is mixed up.

Get a tune up. Replace cap and rotor, spark plugs, spark plug wires, and make sure the wires are in the correct firing order.
The main reason a car misfires is because the spark plug wires are not installed correctly. Check the car's firing order to ensure the spark plug wires running from the distributor cap to the spark plugs (in the cylinders) are in the right order. One or more spark plugs could be damaged or worn so the firing order is correct, but the spark plugs are not sparking into the spark plug wires to ignite the engine.

The spark plug wires in the cap should go clockwise in the firing order. The firing order is: 1-2-3-4-5-6.
There are couple reasons. First, the gap wasn't preinstalled properly you have to change it according requirements. Second, you installed the spark plug wires in not correct order which is bad you have to in the correct order. Third, the spark plug wires are damaged you have to replace it. Forth, check fuses.
what is the correct fireing order for each indiviual coil pack to each spark-plug, i need to know if i have the spark-plug wires connected to the coils in the right spot, and to the right coil
check haynes manual "firing sequence" or "firing order"
Spark plug wires are made in the way when it's really hard to connect wires in a wrong order, they have certain length and a special holder which prevents mistakes during repair process.
If it is backfiring the timing is set incorrectly or the spark plug wires are not connected in the correct order.
Open the hood and chase out the spark plug wires.
