Firing order is 1-8-4-3-6-5-7-2. Move #1 cylinder to where piston is up, and on the compression stroke (TDC). Easiest way to do this is with a compression tester on the #1 cylinder - rotor cap OFF. When you see the pressure build...you're on the compression stroke.
The rotor cap should be at the #1 cylinder firing position...simply re-install the rotor cap at this time - noting which button is #1.
Starting at #1 install the wire for the #1 cylinder onto the rotor cap...the next button (clockwise) on the cap should correlate to #8; the third button on the rotor cap is, cylinder #4..and so on.
work your way around the rotor cap until you have all 8 cylinder wires in place...ignition coil wire in the middle button.

Engine should start and run.

Hope this helps.

Distributor wiring diagram for a 455 Buick hei to engine block



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.

I have an Opel Kadett 200ie, 1996 model. I replaced the plug wires but neglected to mark the proper positions on the distributor cap.

well that firing order is wrong!
an Opel Kadett 200ie, 1996
no country told and 15 engines used world wide this car.
last one in UK is 1995
so I guess it is not UK?
sold under 11 names world wide.
IN UK it is really a Vauxhall Astra Mk II. badged as Opel. now that is confusing.
not diesel, but petrol AND ALL ARE INLINE 4 BANGER'S.
every car made ,every manual for for them in print tells you 2 answers ( distributors)
1: lost all distrib setting
2: or not lost SETTINGS, Crank not turned.

so read that book it tells you to do this.

SPIN ENGINE TO SEE DISTRIB ROTOR ROTATION CCW OR CW/? (HOLD THAT THOUGHT)
by hand
set crank pulley TO TDC ,-0 DEGREE'S AND BOTH VALVES CLOSED #1 CYLINDER. (CALLED FIRING)#1
CAP OFF. MARK ROTOR #1 TO DISTRIB BODY
THEN CAP ON AND MARK #1 ON CAP.
PUT #1 WIRE TO #1 CAP
AND 1,3,4,2, IN CW OR CCW DIRECTION SEEn ABOVE. at FIRST STEP.

DONE car runs.
if distributor was pulled there are 15 engine answers.

next time on all cars made on earth with HV spark wires
do them 1 at a time. and win.
distribs or any car with HV spark wires seen (sets)

Why is my 1992 ford festiva firing in the order 1-2-3-4 and not 1-3-4-2?

Your order is wrong, and you need to switch the wires around on the top of the distributor. First pull the distributor cap off to find direction of rotation (some distributors turn clockwise, and some turn counterclockwise). Watch the rotor, the black bar on top of distributor shaft, and note it's direction of travel while someone bumps the starter over with the ignition switch. Now you can put the dist. cap back on, and arrange the spark plug wires in order 1-3-4-2. Leave number 1 in place, if it is marked as 1 on the cap. The plug wires can be pulled out of the raised terminals in the distributor cap for setting them in order. Just be careful of pulling too ******* the wires, you can cause them to break internally. Twist them back and forth first to loosen them, and gently pull them out, using the plug wire's rubber boot if possible to pull on them.
If it is easier to pull the sparkplug wires off the spark plug, rather than the distributor cap, you could set the order that way. Just need to know the direction of rotor travel. Number1 will go to cylinder 1, and next in order will be number 3, following direction of rotation, so that wire goes to cylinder 3, and on to 4, then 2.
Post back if you need more help. Good luck.

Firing order for a 1986 gmc s15

FIRING ORDERS

To avoid confusion, ALWAYS replace spark plug wires one at a time.

The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.

1984 pontiac bonnerville plug firing order photo

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.

In what order do yu arrange the plug wires on the distributor cap or a 1990 gmc 350

1-8-4-3-6-5-7-2 Distributor turns clockwise Number one should be in the 5 oclock position. You should be able to draw an imaginary straight line between the coil tower and number one tower on the cap and the number one spark plug.
