Title: Coils, spark wires correct seqence :)
Post by: 92BMW318is on December 20, 2009, 04:39:21 PM
sorry guys to repost this, the other thread was getting messy as hell well i found the cylinder firing sequence and this is that fixed my problem with crossing spark wires

      here is a illistarted diagram by me, haha it does its purpose

Right!! :)

OK, so did this fix your problem?

And FYI, the cylinders are number 1 through 4 from front to rear, so the coils would have the non-sequential numbering, not the cylinders.

+1 on that.

I have much shorter Volvo wires which you can actually follow from coil to plug.

Broheim, this is the same thing as in the picture. I assure you it's not wrong. Just rotated 45 degrees.

Wonder if someone installed the coil packs in his car in a different order and just moved the coil input wires back at some point? LOL That would be evil....

this is what my coils look like, along with spark plugs, i dont understand why mine is diffrent

Yup, they are different.  You'll have to chase those wires back to the DME.  Won't take you long.

Just get the pinout numbers and check resistance from the DME harness to the coil harness. For example when you plug into pin #25 and you find the resistance on the other end, that will be cyl #1. Then move that to position number one as I showed in the diagram. You will also need to go to the boneyard and get the bracket to mount the coils correctly.

Or convert to coil on plug.

Why are there zip ties on your spark plug wires?

they are for number coordination.... well they were until i fixed the problem by switching switching 2 of them around

but whats funny is that those coils come with a cover that fits over them perfectly, its like a hard plastic shell, in the shell there is a bmw logo?

i dont know why they would make my coil pack rearanged diffrently, maybe they did this on 92, or just on 318is's, ha or maybe its from a diff bmw,

ill post back with pics on the coil cover

whats this noise sounds like to me that one of the barrings on the water pump or somthing else is going out. you tell me

also once i rev the engine up above 2.5 rpms it goes away

They didn't make yours different. One of the previous owners did that. And the parts you are looking at are correct. The have just been remounted to a different spot and the plastic cover has been removed. The reason for that is the plastic cover is molded to fit the coils when they are mounted correctly in the shape of a square as shown in my diagram. It will not work when they are inline and out of place as yours are.

The OP has an E36, which has the coils arranged differently than the E30 in this photo.

As pictured in the OP's photo, the coils are correct, but the wires, if stock, could be arranged in a much tidier manner.

From '94 on, BMW refined the coil setup even further, with a single input wire from the engine harness, and a smaller, integrated coil pack containing all four coils.
