Seems like you replaced everything on the ignition but the cap. Sounds like a good place to look to me.
Look for burn marks around contacts.

Running on two cylinders


The removal of # 3 & # 4 tells you those cylinders are
contributing the most ,as removing the wire causes the motor
to stop
My guess is that the other cyl #1 & #2 are not firing at all, if there
is no change

If you had a V6 or V8 it would continue to run,not so with only
4 cylinder

Learn or study the ignition system & replace any ignition control
module that fires the first two cylinders

Get an HEI Test Spark Plug & put the plug wire to that & ground it
& see if you get spark,check all the plug wires one at a time.

Don't forget timing belts that are worn & slip,battery voltage,alternator output & A/C Ripple coming out of it

I would check compression or better yet, do a cylinder leak down test.
Could be you have worn valves in #1 & #2 thus little spark
Check fuel pressure at motor with a gauge

What is the firing order of a 1993 s10 2.8L V6 and how are the cylinders numbered


In your truck the firing order is 1-2-3-4-5-6. Number 1 cylinder is on the pass side front. So it is numbered on the pass side from front to rear 1-3-5 and on the drivers side front to rear 2-4-6. The distributer rotor will turn clockwise looking at it from the grill of the truck. Number one plug wire in the cap should be at the 7 o'clock location. going around the cap clockwise starting in the 7 o'clock position, the wires should run 1-2-3-4-5-6.. Note: The 2.8L v6 #1 cylinder location is opposite of the 4.3L v6 or any of the v8's. Hope this helps.
