Dennis,
Where are you getting that if the ecu sees an open Temp II sensor it
provides lots of extra fuel ???????
Are you just assuming that ?
It's well known and observed that if the ECU does not see the Temp II sensor
the engine will not and can not start.
Yes, a cold temp reading from the temp II sensor makes the ecu put in more
fuel.
But 'no contact' from it means 'no fuel' I believe.
Your last two sentences :
This is needed when the fuel does not vaporize. On a warm engine
the fuel vaporizes quickly and the lack of oxygen prevents combustion so
you get the no start.
Doesn't really make sense.
Especially that last sentence, that REALLY doesn't make sense.
Perhaps what you are trying to say makes technical sense, but this last
sentence sure doesn't.
'warm engine, fuel vaporizes quickly' .........that part is ok...........but
'lack of oxygen' ........what lack of oxygen ?
it was mostly likely simply flooded from the spark plugs not igniting the
fuel air mixture that was present. Perhaps the plug wires are 10 years old.
Also..........bearing in mind about 'unflooding' an engine with an air flow
meter..........
While you might be holding the throttle wide open to get air going through
it, the flapper in the air flow meter is still mostly closed , or at idle
position.
And it could be a bad connection to the temp II sensor too.
If it doesn't see that, it won't start.,
But I suspect ordinary 'the plugs didn't fire the mixture there, and got
temporarily wet fouled."

The huge puff of smoke is an indication that the engine was flooded.
Flooding on a warm or hot restart is usually a sign of a bad connection to
or a defective temp 2 sensor. When the ECU sees the sensor open or a high
resistance it says bring on the fuel for a cold start in really cold
weather. This is needed when the fuel does not vaporize. On a warm engine
the fuel vaporizes quickly and the lack of oxygen prevents combustion so
you get the no start.

Hello,
well as i announced this morning ...i passed DEQ and Hoppy is running
GREAT... i went and got my new tags at DMV and then went to the
bank...(all
in hoppy) i was in the bank for 10 minutes came out and hoppy wouldnt
start... it would turn but not kick... checked the coil to see if i was
getting a fire...i was getting consistant fire. checked the fuel pump to
see
if it was humming it was humming. every thing was as it should be... i
could
smell gas so gas was moving and had just filled up this morning ...but no
VROOM...
i called the mechanic he was puzzled and said "just get it towed" (which i
was like, "yeah i am 30 miles from you and i cant pay load up and 3 bucks
a
mile on that!") so i called the tow truck and i was packing my stuff up
and
i thought hmm... i will try one more time... i put the pedal to the floor
and cranked up... huge puff of smoke and strong smell of gas then
VROOOOM!!!
so back to my question: WHAT JUST HAPPENED????
would the fact that i was parked on a incline maybe have been the start of
this non starting? its never done that before... i am just frustrated to
the
max right now. i cant afford to keep putting her in the shop every 2
days...is this some thing i should worry about or chalk it up to a fluke?
