Dont know the firing order to place wires on distributor of 94 blazer

The firing order is printed around the top of the motor beside the valve cover. Did you put a new distributor, rotor cap, or button In it.

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1991-94 2.9L and 3.0L Engines Firing order: 1-4-2-5-3-6 Distributor rotation: Clockwise

991 Chevy S10 firing order
The firing order for a Chevy s10 depends on which engine you have.
1.9L engine the firing order is: 1-3-4-2 . Distributor rotates counterclockwise.
2.0L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise.
2.5L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise.
2.8L engine the firing order is: 1-2-3-4-5-6 . Distributor rotates clockwise.
4.3L engine the firing order is: 1-6-5-4-3-2 . Distributor rotates clockwise.

Recheck the firing order; 1-6-5-4-3-2

Good luck and also check the distributor cap again for proper seating.

If when you changed the distributor cap you misplaced the wires in the incorrect order you could have caused a misfire. When looking at the cap the correct firing order for a 4.3 liter is 165432 going clockwise. Also if you loosened the distributor hold down bolt and turned the distributor even slightly you could cause a misfire.

A few things could cause this: one-if you replaced wires then make sure wires are in right order and if in right order then make sure gap is right on new plugs and/or they are on the right places on distributor cap, two- your right at timing being important but timing would be all the way through, three- the most probable cause is your fuel injection depending on cpi or TPI, I would run a fuel injection cleaner through it for about three tanks or run premium gas for about 5 tanks and that should clear up your problem. Hope this helps....
