Question i just can't figure it out....

to start i have a '97 tj 4.0L with 237000 miles. in mid December the jeep seemed to have blown the engine. the amount of smoke coming out of the exhaust was embarrassing. as it turned out my 9th grade teacher is a jeeper so he came to look at it. he turned the key and it cranked but did not start. he popped the hood and did something under the hood then told me to start it.i had my doubts but when i turned the key it fired up and started (faster than it ever had before) and i can't figure out what he did. (he said it was a trade secret) any ideas?

He may have hit the starter to align the coils. People do it sometimes with a screw driver handle.

It's a temporary fix though. Won't hold your starter forever.

The white smoke isn't good. Sounds like too much oil it's burning. Check your level

Did he say smoke color

Would help to know
Could have been steam
Could be blue oil smoke
Could be black over rich smoke

Not starter as be said it cranked but did not start

Could have been body ground with adequate engine ground will crank but without good body ground for PCM no spark or injector pulse

Or maybe the guy previously pulled your coil wire and replaced it to make it run was it April 1st when this happened?

35 years ago I moved all the distributor wires over one position on my buds 440 roadrunner that he left the hood open on
He could rotate the distributor just far enough to get it almost running right and it took him a couple hrs to figure out what I did.

I had a 98 grand cherokee that when the engine was warm it would not start and when it did it blew black smoke. Took it to a shop and I wouldn't turn it off fearing it wouldn't start. Left it overnight, they worked all day and never found anything. Never did it again. Never figured it out other than possibly some sort of loose electrical connection.

White billowing smoke is anti-freeze burning. Check your radiator fluid level.
