[Mg-t] trouble starting

[oliver]

greetings from Dallas, where on a good evening the temperature drops to almost
80.

we were out in the car, about twilight.  almost an hour later weather.com says
the ambient temperature is 90

we drove the car for about 10 - 15 minutes, then parked for about 10 - 15
minutes.  it would not start, although it seemed to catch for maybe one cycle
or less.

fortunately, we were parked on a hill, and I was able to push start it.  it
was very jerky for about 20 seconds, then ran just fine for the 15 minute
drive home.

vapor lock?
