What is the firing order on a Chevy S-10 2.2 no distr?

Answer

It is a four banger, all four bangers have the same firing order. 1-3-4-2.

The placement of the plug wires on the coils depends on the year. My 1996 S10 from bottom to top on coil is 4-1-3-2. On motor, 1 is by front, 4 is by the fire wall front to back 1-2-3-4.
