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.

my coil packs are set up the same way, but my wires dont run the same as yours there

gwad v2, it still runs of 3,1,4, but start with 2, but thanks for putting up for future reference though for other 1994s

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

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.
