All,
Thank you for reading my post. I have a Jeep that will not start. My
wife went out today, started the jeep, ran it for about 10 seconds and
then shut it off to come back inside to get something she forgot.
When she tried to start the Jeep again, it would turn over but would
not start. The weather is cold (for Atlanta) about 40 degrees F when
this happened. This particular Jeep has always been slow to start, in
the morning, year round, since we've had it.

The Jeep is a 1990 Jeep Cherokee Laredo with a straight six. It has
210k miles on the original engine. (This engine has not been
rebuilt.)

What I've tried with no success:
Start the Jeep normally.
Leave key in run position and hold down gas pedal for one minute then
try to start.
Remove and clean all spark plugs. (They each had a coating of fine
black powder.)
Test the number one cylinder for spark. (There is spark)
Test the fuel rail for pressure. (I don't have a gauge so I simply
removed the cap and depressed the little pin. The pressure was there
when I pressed the pin and pressure returns when the engine is turned
over.)
Check all fluid levels.
Try starting with oil fill cap removed.
Try starting with no air filter installed.

Is it possible that when the engine is started that the car is in open
loop, gas is dumped into the cylinders, it being cold the gas was
still liquid and did not vaporize, and now I have a flooded engine
that I need to let sit for a long time before trying to start again?

I'm out of ideas. Please help me if you can.

Any guess here is strictly set of the pants, but look into:

1- Fuel pressure (might be low)

2- Coolant temperature sensor (might be at a fixed level)

3- Ignition timing (might be retarded)

4- EGR Valve (may be partially open)

5- Take it to a shop that has the proper equipment.
