1987 Mazda P/U 2-2 cu in engine distributaor & plug firing orde

Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. 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 book to reflect how your engine is wired. Fig. 1: 2.3L and 2.5L Engines Firing order: 1-3-4-2 Distributorless Ignition System

take the spark plug out of the hole on the engine. the very front plug.
have someone bump the engine for you. take the cap off of the distributor, and when your friend bumps the engine watch the way the rotor is turning. i think its counterclock wise. but anyway, hold your finger over the spark plug hole and have the friend bump -bump- bump the key until the air pressure "Pssst" blows your finger out of the hole. thats the compression stroke of your engine. and right now its set to send a spark to that #1 piston.
SO look at the rotor, and pay attention to what direction the rotor is pointed. and when you put your distributor cap back on, your wire for #1 spark plug has to be pointed at the rotors tip, to get spark. so put cap back on, and then put #1 at the rotor tip, and remember what direction the rotor spins ? now put your spark plug wires on the cap to match the "firing order" The firing order is 1-3-4-2 with the cylinder closest to the front of the vehicle being #1 so if the rotor spins backwards . wherever the rotor tip is now ( since you bumped it to the compresson stroke ) on the #1 cylinder, you know where 1 is. now put #3 piston wire on the next plug, on the distributor then 4 , then 2. tighten everything, put the spark plug back in. and start your truck bro.

Several engine sizes there, if you have exactly the sizes, send us; check this sample...

Hope helps.

Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. 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 book to reflect how your engine is wired.

You didn't put your engine size so choose the one that is applicable:

1987 Mazda B Series Truck
2.0 liter L4


1987 Mazda B Series Truck 2WD
2.6 liter SOHC L4


1987 Mazda B Series Truck 4WD
2.6 liter SOHC L4

you didn't say if you have the straight 6 or v 6.But i'll give the order for both.
The 4.9L straight 6 is 1-5-3-6-2-4----------- distributor rotor turning clockwise, and #1 plug is the first plug.
On the 3.0 and 4.2 V6 engines is 1-4-2-5-3-6-------#1 plug is the first plug on driver side---- facing engine.
