MX6-LS firing order

3-6-03, 21:17

What is the firing order for the six cylinder hemi head engine? Have looked & checked the forums, no answer. Used to be inside the hood, but not replaced with the hood.

From what I have read and heard it is 1-2-3-4-5-6

you're right. Is it 1 from left or right, facing the engine?. even are to the front of engine well, odd to the back.

1) It's not a hemi head, it's a pent-roof chamber design.

2) Firing order is 1-2-3-4-5-6, where the cylinder numbering is:

firewall
1 3 5
2 4 6
radiator

3) Use care when tracing wires back to the disty cap. The order of the towers does not match the firing order. IIRC, towers 4 and 5 are swapped. The firing order is still 1-2-3-4-5-6 but the wires on the cap appear to be 1-2-3-5-4-6

4) The lounge is not the correct forum for this topic. We have forums for the 1st and 2nd-gen cars, both for issues like this and for performance modifications. Moving...

so the dist cap is labeled wrong? I noticed this when i was diagnosing a prob. i couldnt tell if the manual labeled the firing order wrong or the distributer labels were wrong.

No, the cap is correct. The external wire connection to the towers is indeed 1-2-3-5-4-6. You'll notice that the cap towers are not evenly spaced around the periphery of the cap as you might expect for an even-firing V6. Instead, there's a row of connections on the top and a row on the bottom. If you remove the cap and look inside, you'll see that the contacts inside are spaced at 60-degree intervals and that there are raised "runners" within the plastic that cover conductors that run to each of the plug towers. If you follow the contacts to the towers, you'll see that 4 and 5 cross: even though the towers are ordered ...5-4... the rotors passes the contacts in the order 1-2-3-4-5-6.

Mike, I noticed in a previous reply you said this was not the right forum for these questions? Please tell me where the right forum is located...
I have a 93 MX6, GS, and my distributor cap is numbered top 453, bottom 612, with the 6 being the offset connection. I have a Chilton's that says the firing order is 123456, the drawing shows that the distributor is top 546, bottom 123, and the wells are shown as firewall 135, 246 radiator.
From what you are saying, what the distributor cap says is what well that wire belongs to? I labeled my wires but got confused by the manual... Now I'm not sure what goes where...

What's a 2002 MGT?
