How do you find the firing order for a 351 v8?

Answer 1

On ALL 351 Ford V8s, regardless of year and engine family, the firing order is 1-3-7-2-6-5-4-8. The distributor spins counter-clockwise and from above the engine, the cylinders are numbered 1, 2, 3, 4 on the passenger side from front to back and 5, 6, 7, 8 on the driver side from front to back.

I will try to explain in the simplest way. a) You need to know the cylinder nos first. Then Follow the spark plug lead from plug towards the distributor cap, mark that # on the distributor cap. b) next take off the distributor cap. c) rotate the engine slowly in correct direction (in which your engine rotates when it is running). d) now the rotar in your distributor with rotate too. Observe the order in which it passes by the spark plug lead. This is your firing order.

Sometimes it is cast right in the block of the engine in letters. Sometimes it is in the owners manual. It is usually in a shop mechanic book. You can also find your particular order online by make and model and year.

If you don't want to buy a manual for your vehicle which you can get at most auto parts stores now for around $9-$15, Most public libraries carry these books on the shelf or for those without home internet service, you can use theirs either free or very cheap.

This shows the engine firing order for each spark plug. The newer Distributor Caps have the spark plug number, so if you know which is number one on the distributor cap and on the engine, and so on, you are good as gold.

Also, when removing the existing wiring, you should also replace the distributor cap and rotor. It is usually a good idea every 50,000 miles.

The firing order of a 1992 Ford 351 V8 is as follows: Firing order is 1-3-7-2-6-5-4-8. On the distributor,it goes counterclockwise (CCW). Passenger side is cylinders 1-2-3-4 (front to back). Driver side is 5-6-7-8 (front to back).

If you live in an area that has a local autozone you can call them up and they can give it to you. If you do not leave me your vehicles make model year and engine size and i will get it to you as fast as i can.

It is almost always stamped on the top of the intake manifold or on the engine block itself.

The quickest way to find the correct firing order without looking around the engine (especially dirty and oily engines) is to call your local auto parts dealer (Autozone, NAPA, etc.) and ask them. All you need is the general engine and car specs.

I have a 1993 Saturn SC2 Coupe, and got my wires mixed up when I was replacing them. I called AutoZone and the guy told me that the firing order is 4-1-3-2. I installed the wires in this order, started up the car, and it idled VERY roughly. I immediately shut it off and called a local Saturn dealership. The guy in the service department told me that the correct firing order is 4-1-2-3. I reconnected my wires and it started right up and idled perfectly. A word of caution: many times "the guys" at your local auto parts stores can point you in the right direction, but they are not necessarily the experts. If you ever have questions like the firing order, go straight to the source. Call the experts at the dealership for your car's make.
