I have been having this problem with my 1991 Accura Integra for about a
year now:

Usually when i first put the key in the ignition, the check engine light
will come on, but go off after a couple of seconds, and the car will
start perfectly. However, other times, the light will stay on and as
long as the light is lit, the engine refuses to start. It SOUNDS
perfectly normal, just like it does when it starts with the light off,
(i mean the cranking and everything it usually does before it starts),
but nothing actually ever catches on. If i wait sometimes, the light
will go off, and immediately the car will be able to start. It seems
that as long as the light is on - no start, but if off - it always
starts perfectly fine. So it appears from the driver's perspective that
the car's ability to start is purely a function of the light's being on
or off.

Does anybody know why this happens? it seems to happen slightly more
when it is hot outside.

Thanks in advance for any info
