Have searched, found multiple results - alot conflicting.

Have tried:

4...........8
3...........7
2...........6
1...........5



7/8.....1/3
4/2.....6/5


also have tried it like this:

6/3.....7/2
1/5.....4/8


It will not fire up, turns over fine, starts to catch (but won't) - something is still wrong. Have plenty of fuel pressure.

This is a car I bought that originally ran, but now bucks/farts/knocks/stalls/you-name-it.

Just want to verify it runs properly before I carve it up like Christmas turkey :skull:.

If you're looking for which wires from the coil go where, it should have worked based on your second diagram. Mine is arranged the same way -
Looking at the coils from the front of the car:

Pass. / Driver
6 - 3 / 7 - 2
1 - 5 / 4 - 8

A 96 4.6L is 1-3-7-2-6-5-4-8

Coils Right 6-3
1-5

left 7-2
4-8
The first part, 1-3-7-2-6-5-4-8, what's this regarding, cylinder layout? I thought ALL 4.6's were 1-4 passenger side, 5-8 driver side?

Am going to try the coil pack layout your way, haven't seen that one before.

OK, just went out and switched the wires around again, no difference.

There's got to be something else wrong with this POS.

Thanks anyways guys, it can't be the wiring if 3 different ways won't let it fire - but I'm going to leave it your way Brandon.

heres a big ass picture of my 4.6, currently running.

I believe the above posted order was correct. you can't see the right coil too much, but you can easily make out the left coil pack, and it matches what's posted above.
the cylinder numbering is correct also, passenger side, from front to back is 1234, and driver side front to back is 5678

I believe Darren was referencing firing order with his post. His coil layouts are correct as well.

I'd check to see if all your plugs are firing. If you'd rather not take each one out, remove one and use it to test each of the wires.

I don't mean to sound like I'm giving you a lazy answer, but I would go invest in a Chiltons or a Haynes. It gives you diagrams of how the wires are ran and plus I'm sure it would come in handy with other stuff also.

But my book does show one of the options you have tried....

6/3.....7/2
1/5.....4/8
(front of engine)

Nope, that's usually what I would think - consult the manual. But it's not accurate! Pretty sad that there's 3 different options out there for this.

It's got to be something else, the plugs are new, it used to fire up no problem, just not run worth a crap. Hence my finding out the proper wiring sequence, as I had tried what was in the manual and what was online.

I will continue to mess with it, and probably give up - then carve it up with my saw-zall.

Big Johnny - thanks for the mega-pic, will use that as reference to make sure mine is right.

Is Casper running?

I feel like you got good information, just what did you find out to be the problem? Want to know, because you have great car there, ( if you can live with the fact you stole the car for that money you paid.) Good luck, with finding Casper in the snow.

I just realized, the coil packs themselves have the numbers on each tower...you should be able to look at your coil packs and go from there.

maybe you have the packs on the wrong sides?

Yes, the packs have numbers on them - for either side. It doesn't matter what side the packs are on, just what side they're plugged into in relation to what plug wires are hooked up.

well, if you have the left pack on the right side, andhave the wires connected as per the numbers on the packs, wouldn't the computer be commanding the wrong cylinders to fire?

so, If I have the pack with cylinder 6/3/1/5 on the right side, when the engine commands cylinder 7 to fire, it will be firing the wrong cylinder since #6 would be connected to the right spot as far as wiring, but the computer would actually be sending the signal to fire #7 but #6 is actually what's there.
does that make sense???

If anyone wants to PM me with their e-mail address, I have a diagram from the factory service manual that shows how the plug wires should be routed. I can send it to you.

I'll eventually figure-out how to post pics on this forum! :confused:

you need to upload the pics somewhere like photobucket, or your own host, then you link to it using the IMG tags.

Are you sure?

While under the hood, I checked my coil towers. Both were numbered the same. 1-5, 6,3 . I bought the car used, and have never change plugs, or wires. The Ford wires are unmarked except for their name and 8mm, with some goofy looking symbol, no cyl numbers on them.

The cylinders on the passenger-side of a 4.6 liter V-8 are numbered 1, 2, 3 and 4, starting at the front and going back to the firewall. The cylinders on the driver's-side are numbered 5, 6, 7 and 8, again starting at the front and going back to the firewall.

If you were above the coil packs and were to look directly down on them, the coil pack on the passenger-side fires cylinders 1, 6, 3 and 5, starting at the lower left and going clockwise. This means that two of the plug wires, for cylinders 5 and 6, go over (or under) the alternator to the driver's-side of the engine.

The coil pack on the driver's-side fires cylinders 4, 7, 2 and 8, starting at the lower-left plug terminal (again, when looking directly down onto the coil pack from above it) and going clockwise. This means that the plug wires for cylinders 2 and 4 cross over (or under, whatever your preference is) the alternator and go to the passenger-side of the motor.

Does this help? I hope I haven't confused you even further!

One other thing - there are no "left" or "right" coil packs. They are all the same; the computer determines when and where to send the ignition pulses.

Nope, not more confused... I'm just letting the folks know about the coil towers on mine. Both are the same, looking down at the numbers from above. So the passenger side is the same the drivers side. Got zippo for the 4, 7, 2, and 8. Which tells me both towers are the same. Car runs great, and when I do change the plug wires, it will be one wire at a time.
