Question type: Maintenance & Repair

I have a Chevy S10 1993 V6 4.3 liter codes read 12
+ 43 I'm changing the distributor today because
when I looked at the old one wires were fried I'm
also changing knock sensor on left side of the
engine it's loose do you think this will change the
problem of it not starting. Fuel pump is good I
changed the coil already too

Did you ever figure this out? I replaced my distributor bc my engine was misfiring and it still wont start but it did help the sputtering and misfiring when attempting to crank

Hello out there I need some information. I've got a 1993 S10 Blazer with a 4.3 v6 CPI and I need and I found a 4.3 v6 engine not sure what year it is or what it came out of. It's a long block. So what do I need to do and look for to see if I am able to use this engine in my 1993 S10


Your not sure what year the engine is that you have thats not in the blazer currently?

The engine that's in my blazer is the original engine that's in there right now. And I found an engine 4.3 v6 it's a long block. But I'm not sure if I could use the engine there not like the small blocks that you could pull out of a car or truck and put it in a different car if that makes sense


Oh so your wanting to engine swap it with the engine but your not sure if it'll work? Alot of people end up putting 350's in their s10 blazers, i have a 94 cpi 4.3 and if i happened up on a good 350 for cheap id have a good pulling truck indeed and those are v8 and will fit in place of the current v6.
