Herm.... That's very interesting. Here's what the coil packs on my 1994 looked like:

(clickable version) ---> 1994 Coil Packs - Firing Order

From left to right, mine are hooked up 2-3-1-4.

That's odd that an all electric S10 (VIN H) has a spark plug firing order

Re: Firing Order for 1994-2003

hmm, interesting. 1+4 are always going to be paired together, allong with 2+3. how you put the wires on shouldn't make a difference as long as you pair the cylinders to the right coil pack.

Firing order will be 1 - 3 - 4 - 2, with wires on the coil pack being 1,4,2,3. You can switch 1/4, or 2/3 on the coils.
