What is the Wire Order with distributor? - 1987 Buick Regal

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.

#1 plug is closest to the front. Take off distributor cap. Remove #1 plug. You want to crank engine until #1 cylinder is on compression stroke. Watch to see direction the distributor rotor is turning. As the compression stroke starts then bring the engine to top dead center by aligning timing mark on crak shaft pulley with pointer. The #1 plug wire goes in the distributor cap hole the rotor is pointing. The #2 wire in the next hole following the direction the rotor turned. Then the #4 wire and finally #3. Firing order 1-2-4-3.

It sounds like the spark plug wires are not plugged into the correct place on the distrubutor. take the distributor cap off and crank the engine over. Make a note of which direction the rotor spins. (Clockwise, or Counterclockwise) then find the firing order for that engine. Sometimes the firing order is on the intake manifold. (if you tell me which engine it has, the 4 cylinder 2.0, or the 6 cylinder 2.5; I could post you the firing order). Now on the distributor cap there is one wire post that has the #1 on it, that would be where you put the spark plug wire from cylinder 1. Following the rotation of the distributor rotor, you would put the spark plug wire for the next cylinder in the firing order after the #1 wire, and so on.

Back trace what you did. You may have unplugged something and forget to re-connect it. You mean the distributor cap,,,,, or the ENTIRE distributor???? If the later, then you must be 180 degrees off.

350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.

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.

Hope this helps...

firing order 1342, distributor, clockwise rotation.

If you have the 3 cylinder engine, the firing order is 1/3/2. The distributor rotation is counter-clockwise looking at it from above, and the #1 spark plug wire goes on the distributor pin closest to the driver side fender.
If you have the 4 cylinder engine, the firing order is 1/3/4/2. The distributor rotation is also counter-clockwise, and the #1 wire goes on the distributor pin closest to the front passenger headlight.
Hope this helps!
