What is the firing order for a gsx400 for the plug leads to the plugs thankyou

Could I have more information please. What year is this MX6? What size engine is it? Are the plug leads still in place on the vehicle?
There were 2 different V6 engines Mazda used and the firing orders were not always the same so engine size will help.
The plug leads are deliberately different lengths for a few reasons. When connected to the coil in the correct firing order the length will only allow the lead to go to certain spark plugs to help get the correct firing order, shorter leads look tidy on the engine and shorter leads cost less money to make for the manufacturer.

Which engine do you have in the vehicle? They fitted them with an in-line four cylinder and a V6. The firing orders are different for each version. I'm assuming the distributor has NOT been removed and is set correctly!
**Note, Take your time to make sure you get this right!**
The Four cylinder is the standard 1,3,4,2, firing order with number One being the nearest cylinder, (spark plug), to the belts and pulleys on the engine. Use the plug leads as a guide as they should be four different lengths. The longest plug lead to the spark plug furthest away, shortest to the nearest spark plug.
With the distributor cap removed make sure the engine is at Top Dead Centre for cylinder One. Check where the metal tip on the rotor arm is pointing as this is where the plug lead for Number One should go.
Refit the the distributor cap and insert the lead for the Number One spark plug into the hole nearest where the rotor arm tip was pointing. Now refit the remaining 3 plug leads in the Correct Order, (1,3,4,2,) into the remaining 3 outside holes in a CLOCKWISE direction. The centre hole should connect to the coil pack lead.
A V6 engine uses the same setup BUT a different firing order. (See photo). 1,4,2,5,3,6. In the photo numbers 1 and 4 are nearest the belts and pulleys.
Set your distributor as you would for the four cylinder engine, fit plug lead one and going CLOCKWISE fit them as the 1,4,2,5,3,6 sequence.

there is no set order in replacing spark plugs
however if you are asking the firing order for the plugs leads to fit to the spark plugs, simply remove one lead at a time , one plug at a time and replace that lead then move onto the next plug

need to know what year, make, model and engine is in your car to help.

not necessarily-- it complies with the position of the rotor button and the lead it points to in the firing order
so start with the rotor button facing no one piston lead with the piston on tdc compression
put the lead to no one plug
move the crank in the direction of rotation and when the rotor button points to another lead that is the next plug to connect to
so with a firing order of 153624 (example) the lead wil be on the point when no one piston is on tdc compression
the next point will be no 5 piston ,the next point will be no 3 plug and so on
work shop manuals are a good source of accurate information

on the left ,i thought the firing was 1342

possibly all you got wrong is the firing order for the plug wires. Put the engine on no 1 firing as per the timing mark and see which plug lead that rotor button is pointing to. Use that as no 1 lead and adjust the rest of the leads to suit the firing order. IF by chance that the rotor button points between the contacts in the cap the pull the distributor and turn the rotor button until when you have the distributor back in ,the button is pointing to a plug lead contact and adjust the firing order from that.

You need to start by turning the crankshaft pulley to TDC (top Dead Centre) There should be an alignment mark on there for reference. Once you have this, then remove the distributor cap and refer to the position of the rotor arm. It is pointing to number 1 plug lead (number 1 cylinder). You can start from that reference and hook up No.1 plug lead. Then, as your rotor arm turns clockwise, it should hit the following cylinders in this sequence: 1,8,4,3,6,5,7,2.


1,3,5,7 refers to the left bank and 2,4,6,8 refers to the right bank.

Will this work?

most bikes fire in the order of 1,3,4,2 so with 1 coil it should split to 2 plugs. check the lead length to which plug it should go to ie 1-3 & 2-4. hope this helps
