Hey all, I am replacing my coil pack for cylinders 1 and 4(same pack). But I am having difficulty matching the right wires with the right cylinders. Can anyone show me how the wires are supposed to connect. I know the firing, got it off of another question, but i have no idea how this engine is layed out.

From the front of the car, 1 is first, and 4 is second on the coilpack. The rear bank of the car has cylinders 2-4-6 from the front of the engine, from pass side to drivers side.
The front bank, is 1-3-5.

BTW, welcome to Chevytalk. I love the 3800, its a great reliable engine, I have one in my LeSabre.

Thanks Tim, I will give it a try. And yes, I do love the 3800 (Except for the placement of those back plugs, I'm going to kill whoever designed it that way).

95 buick regal limited. Still having problems getting it to start. I followed the labels that was on the coil packs originally and matched them up with the cylinder numbers that you've listed. Right now, this is how my coils packs are set up: top coil pack- 6 and 3, middle coil pack- 1 and 4, and bottom coil pack- 5 and 2.

Aha! Thats where your problem is!

I'll give you the proper layout.

Top coil pack, from top to bottom. 6-3 Second pack, 2-5 Third, and bottom, 4-1
Top bank of cylinders, from front of the engine(Not front of car) 2,4,6. Bottom bank, from front, 1,3,5.

Now is it correct?

Don't know why, but it's still missing whenever I step on it. Could it be the fuel filter? or maybe another bad coil?
