2002 Chevy Blazer LS will not fire. Engine Cranks, well, but will not fire. Was left to sit unstarted two foggy days, then temperature fell to 16 degrees. Now it cranks but will not start

First I would like you to check for bright blue well defined sparks at the #1 cylinder, if that is good try some starting fluid, does it start right up?

Post back your results.

2002 Chevy Blazer LS will not fire. Engine Cranks, well, but will not fire. Was left to sit unstarted two foggy days, then temperature fell to 16 degrees. Now it cranks but will not start.

I used some fluid and, with some coaxing, it started. It ran a few minutes, then ran rough and died. Was not able to restart. When it died, though, there was a strong sulfurous odor and when I tried to start it again, there was a knocking sound wherein the starter stopped turning: Rr-Rr-Rr-clunk. Rr-Rr-Rr-clunk. Preignition?

Is it a slow crank?

Or is it a normal crank.

When it clunks does the starter stop turning untill the key is let off?

And is the clunking coming from the starter or engine.

I believe the starter may have become hot and began to drag. Anyway, I got it started and ran it at high and low RPM. The main concern now is that there doesn't seem to be enough air for the mixture, as it lags and idles poorly for a bit after giving it gas. I also had to leave the cover off the throttle housing so it wouldn't die. Perhaps it was badly flooded. Anyway, the "Service Engine light stays on and the oil pressure fluctuates with the idle speed. Perhaps this is caused by gas in the oil, but I am unsure.

Can you get it scanned for trouble codes?

The reason the oil pressure is fluctuating is probably the fact the engine is idling and running rough.

Started right up this morning, drove it some, turned it off and restarted. It apparently runs well, but Service Engine light remains on.

You might want to get that checked, funny how things act up for a day or two and they are good.

It will come back more then likely.
