the rotor should be pointing towards the number one plug position on the distributor cap, and the engine should be on compression stroke. If its not the motor will be 180 degrees out

once the number 1 piston is on tdc which ever point the rotor is facing becomes the number one position. if you conect the wires from there and follow your firing order you should have no problems.(i have done it)

Bring #1 piston to its uppermost point and observe position of distributor--it should be firing on no. 1

THERE SHOULD BE FIRING ORDER ON THE INTAKE MANAFOLD LOOK FOR NUMBER 1 AND YOU SHOULD BE HOME FREE GOOD LUCK John Note that on nearly every engine in the world the number 1 piston is going to be the one farthest forward on the block (IE closest to the radiator). On the Mitsubishi 3.0 v6 the firing order is 1,2,3,4,5,6. You will start with number one. It should be at about the 9 O'clock position. The problem is that the distributor cap is internally wired and the cap is marked for the correct plug wire. The engine will fire correctly if you wire the cap as marked. The cylinders are 1,3,5, ont he passeger side front bumper to windshield and 2,4,6 on the drivers side.

Not Sure What You Are Asking. The Number One Plug Is The First Cylinder On Your Right From Front Of Engine. But Are You Wanting To Know Where Number One Is In The Cap ? The Firing Order Should Be 1-2-3-4-5-6 if you have a 2.8 I`m Pretty Sure Of This. To Actually Find The Position Of The Number One In The Cap You Will Need To Get The Engine On #1 Firing Stroke or TDC. Then Look At Position Of Rotor It Will Be Pointing Toward Position Of Number One. Hope This Helps

On every car (I guess) you can try to push it with your hand and it should take its original position. If that does not work, take a C-Clamp and protect the piston with a piece of carton and it should take its original position.

If you mean which point on the distributor cap, the easiest way to find it is to set number one piston at top dead center and see where the rotor is pointing in relation to the distributor cap - the rotor should be pointing to the location of number one park plug wire firing point - this is where the number one spark plug wire should be connected. The rest of the wires are connected according to their firing order.

Firing order is: 142536 and number 1 post should be marked on cap.

For a v6 it is 123456 and for a 4 cylinder it is 1342. The distributor caps should also have the piston numbers marked on top.

if the number one piston is at top dead center the rotor should point at number one spark plug wire and rotate toward the next spark plug wire in the firing order.

#1 piston should be at TDC and both valves closed (compression stroke)

If this is a 305/350/400 small block Take the lead from the coil to the distributor "OFF" to prevent the engine from firing. This will take two people or a remote starter. Turn the engine over until the mark on the tortional damper lines up with the center or O mark on the timing tab on the front of the engine fastened to the crankcase front cover and the engine is in the number one firing position. This may be determined by placing fingers on the nuber one valve as the mark on the damper comes near the O mark on the crankshaft front cover.If the valves are not moving the engine is in the number one firing position.If the valves move as the mark comes up to the timing tab the engine is in number 6 position and should be rotated one more complete turn to bring it to the number one firing position. Also take the cover off of the distributor to determine that the rotor is positioned properly pointing to the number one spark plug then follow the firing order for that engine should be 1,8,4,3,6,5,7,2 Wayne

firing order should be 1 3 4 2 number one being next to cambelt pulley

The gap should be closed on piston rings because of if there will gap on piston rigs it cause leakage of gasses which are produced by the ignition of air-fule mixture to provide force on piston by which piston reciprocate in piston chamber, it provide power stroke. If there will be gap on piston rings power stroke will not be provide...... AMIT DAGAR

Front of Truck 1 5 2 6 3 7 4 8 drivers side/pass side should be able to look on top of manifold by heads and see cyl #s it should also show the firing order.

Easiest way to find it is to set #1 piston at TDC and remove the distributor cap to see where the rotor is pointing. It should be pointing to #1 cylinder position in relation to the distributor cap.

should be passengerside front,(right behind alt.

What should Firing pin protrusion measure?

The distributor position will have to be set by turning the engine to TDC and then make sure that the rotor button is pointed to #1 on the distributor cap. This should be indicated by a 1 stamped on top of the cap. As for the firing order, it should be 1-3-4-2 but it will be stamped on the intake manifold for verification.

you probably have a coil pack assy. that is breaking down.have a place scan the computer, you should have a p0301-p0308.the last number is the cylinder that is missing.a coil pack and spark plug should fix it.

take number 1 spark plug out and bring that piston to top dead center. Then take distributor cap off. Locate which tower the rotor is pointing to on the cap. That will be the number 1 plug wire. Then just follow the firing order. The rotor should turn clockwise.

Easiest way to find it is to set #1 piston at TDC, remove the distributor cap and see where the rotor is pointing. It should be pointing to position #1 in relation to the distributor cap.

piston should have an arrow on the top .It should be pointing toward the exhaust pipe or the front of machine.

Yes the rotor should be pointing to the #1 cylinder when you are installing the distributor.

the firing order should be 1,3,4,2.
