What is the firing order.Need to replace coil on plug number 7?

1 - 3 - 7 - 2 - 6 - 5 - 4 - 8

It has the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils

The engine cylinder locations are numbered :

firewall

4 - 8

3 - 7

2 - 6

1 - 5

front of Ford F-150 ( V8 )

the order shown is the order they fire in ..1 -8-4-3-6-5-7-2..bring number one to top dead center timing mark and make sure the rotor is pointed to number one plug lead..unless it has multiple coils as some models do..good luck repost findings

a haynes manual from a parts place will show you--or chec the condition of each plug wire-if one looks bad or falls apart--probly need to get all new wires /plugs

Okay, on the photos I am posting, pick the size of motor that you have....since you didn't post it. When you find the right photo of your motor, the numbers on the engine correspond to the number of the spark plug that goes to the coil...1 to 1, 2 to 2 and so on. This is your firing order and will ensure you have the proper spark plug firing from the correct point:



1FZ-FE engine Firing order: 1–5–3–6–2–4Distributor rotation: counterclockwise



5VZ-FE engine Firing order: 1–2–3–4–5–6Distributorless ignition system



2RZ-FE and 3RZ-FE engines Firing order: 1–3–4–2Distributor rotation: clockwise



2RZ-FE and 3RZ-FE engines Firing orders: 1–3–4–2Distributorless ignition system



2UZ-FE engines Firing order: 1–8–4–3–6–5–7–2Distributorless ignition system

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.
If a coil is replaced on any of the 3.1L, 3.4L or 3.8L engines, it may not be numbered, as is the factory coil. 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 in your guide to reflect how your engine is wired.

The firing order for the 3.1L VIN M, 3.4L VIN E, 3.4L VIN X and 3.5L VIN H engines is 1-2-3-4-5-6. The right bank cylinders are on the cowl side (rear) of the engine compartment and are numbered 1,3,5, left bank cylinders on the front side of the vehicle, are numbered 2,4,6.
The firing order for the 3.8L VIN K and 3.8L VIN 1 engines is 1-6-5-4-3-2. Starting at the front of the engine, cylinders in the left bank are numbered 1,3,5 and cylinders in the right bank are numbered 2,4,6

If this is a truck with The coil on Plug setup, I would suggest replacing the #7 ignition coil and the plug.
