I am looking for a picture or diagram that shows the proper position of the distributor on an 81 datsun 280 zx straight 6 engine. that shows the #1 plug wire position with respect to the engine.

145

I assume its a V8 and probably a 5.0L

5.0= 1-5-4-2-6-3-7-8 firing order

5.0 HO and 351 Windsor share 1-3-7-2-6-5-4-8 firing order

Cylinder numbering:

When looking into the engine bay the number one cylinder should be on your left hand side (left bank) at the front of the engine. The number eight cylinder is on the rear right (right bank) up against the firewall.

distributer turns counter clockwize (#1 should be labelled on cap)

Datsun 240Z 260Z 280Z 280ZX Wiring Diagrams

Firing order is 1 3 4 2. Distributor rotor turns counter-clockwise.

Standing in front of car looking at engine, number one cylinder tower is in the 4 o'clock position, number 3 cylinder tower is at the two o'clock position, number 4 cylinder is at 10 o'clock, and number two cylinder tower is at the 8 o'clock position.

1-5-3-6-2-4 is the spark plug firing order for the 4.9 L ( 300 cubic inch ) straight 6

The distributor rotor turns CLOCKWISE

The marked # 1 position on the distributor cap is installed facing away from the engine

Hope this helps

Hello kat801931,

The firing order is:

1 5 3 6 2 4

Below is a picture of the cylinder order and the distributor. Number 1 cylinder is at the "white" location on the distributor. Good luck.

OKAY STANDING IN FRONT OF ENGINE ON LEFT SIDE CYLINDERS FACING YOU IS 1 3 5 ON RIGHT SIDE DRIVER SIDE CYLINDERS FACING YOU IS 2 4 6 LOOKING AT DISTRIBUTOR CAP NUMBER 1 SPARK PLUG ON CAP IN THE 9 OCLOCK POSITION YOUR NUMBER 5 SPARK PLUG ON DISTRIBUTOR CAP IN 6 OCLOCK POSITION .STARTING AT NUMBER 1 SPARK PLUG ON CAP COUNTING CLOCKWISE COUNTING 1 2 3 4 5 6 THATS YOUR SPARK PLUGS WIRES ON CAP TO ENGINE PLUGS. 6 PLUG WIRE ON CAP IS AT 7 OCLOCK POSITION.

Hi: To Install the Distributor Correctly, 1st thing to do is Remove your #1 Spark Plug assuming it will turn over have someone Turn the Key Off and On in Short Intervals.Either put a Compression Gauge in the #1 Spark Plug HoleOr the Old Fashion Way Works as well just put your Finger in the #1 Plug Hole.As your Helper Cranks the Engine On -Off On -Off.Not A Continuous Crank.When You Feel Air Pressure or See gauge Come up.TYhats when your Engine is a The compression Stroke.Now you Can Drop the New Distributor in its Hole.NOTE: You'll need a Spark Plug and Timing Diagram to See the Position your Distributor ROTOR Line it up to where the Diagram Shows your #1 Spark Plug Wire Will go in the Distributor Cap.If the Distributor Rotor is Not n That Position Your goning to Get Either Back Firing engine May Not Even Stsrt, To This Is Crucial. After The Know that you have The Distributor Droppped The Right position you'll need to Put Gap your Plugs at the Correct Specs, With All Plugs in Now You'll need to Put New Plug Wires on .And They MUST be in the correct order.Sitting inside your Vehicle #1 Plug is the Front Plug on the Drivers Side Next is #3 plug Next is #5 and Your Back Plug is Number 7,On the other side Passenger Front Plug is #2 next #4 Next is #6 and the Back is #8 Assuming you know have your Distributor Dropped in The Proper Position, Put the #1 Spark Plug Wire on the Front Spark Plug (Drivers Side) The Spark Plug Firing Order in Your Engine is 1-8-4-3-6-5-7-2 Clockwise So the Next hole after you have #1 Plug and Wire on And Distributor In Correct Position on COMPRESSION STOKE, Going Clockwise you next wire will be your #8 Position in The Cap And it wil go to the Back Spark Plug on The Rear Spark Plug on Passenger Side. NOTE: Drivers Side Spark Plugs on the Drivers Side Front to Back are Your Odd Numbers 1-3-5-7 Pasenger Side is Your Even Numbers From The Front is #2-4-6-8 Is The Rear PLug .

Remove the rocker cover.
Turn the engine until it's at TDC on No.1
Both No.1 rockers should be loose.
Remove distributor cap and look where rotor is pointing, this is No.1 plug lead.

Turn your crank pulley and line the timing marks to top dead center,pull the distribuor cap and see where the rotor points to, thats where the #1 position is located.
