Engine Mechanical problem





Two Wheel Drive


110, 000 miles

Just redeployed back to the states a few weeks ago. 1992 Chevy S-10. Ran great, didnt do a darn thing to the truck even though it sat for a whole year, except for a new battery.

But on this day, drove it to work in the AM, perfect.

Evening time, jumped in, cranked it over, and it continued cranking. After several cranks and rest time in-between cranks it started trying to turn over, sputtering and spitting heavy white exhaust.

Anytime I would not pump the gas, it would immediatly stop sputtering and stall.

This will be the first true mechanical-engine problem and hasn't given me any noticible signs leading to this grand event.

Now, after several attempts with duplicate results, I have given up for the night.

After reading the forum I see a lot of people tackling; fuel pump, distributor cap, sending unit, ECM switch-fuse, EGR Valve, Plugs-Wires.

Let me know what you guys think.

1992 Chevy S10 4.3 6cyl Two Wheel Drive

Woke up first thing this AM and heading right over to a chained part store and picked up the following;

Distributor Cap - $10.00
Ignition Control Module - $42.00
Ignition Coil - $22.00
Ignition Rotor - $6.00
Fuel Filter - $10.00
Spark Plugs (6) - $13.00
Wires - $17.00
EGR Valve - $50.00
PVC Valve $2.00
Starting fluid (to clean certain components),

And of course a manual in case I ran into any unfamiliar specifications. Didn't even pull the plastic off, as everything was visual and took more patience then effort.

After about 4.5 hours of locating, pulling all this off, cleaning surfaces, applying anti-seize and all the right lubes for electrical surfaces, and of course putting it back together. Not to mention some of the replacements were different then the original so it took extra time figuring how the changes applied with installation (such as brackets, bolts, clips, mounting).

Now all installed ---- Started right the heck up, and it sputtered for about 4 - 6 seconds and then it cleared right up and has been starting up and running like a TOP all day.

Not exactly sure which specific component failed, as all of these parts could have been the culprit. Everything listed here really, for my knowledge produce similar-same problems. But everything I pulled off, in reality really really needed to be replaced. Blackened, oily electrical components, plugs and wires were corroded.

Hopefully this topic, answers, and updates will help someone in the future.

Thanks 2carpros.
