The car cranks fine. It runs fine once engine starts.
It starts fine when cold.
It needs to have the gas pedal pumped and pumped and pumped when
starting hot.
Once the gas pedal is pumped enough during a hot start to get it to run,
the car runs fine.

It's not an intermittent problem; it happens on every hot start.

It gives the indication of flooding only during hot starts; once the
car's running, it runs like nothing's wrong with it. It doesn't flood on
cold starts.

And this is the really weird part of the whole problem: once the car
starts, it runs exactly as it should.

I'm thinking this is the logic the car uses when a start command
(turning the key to the "start" position) is issued:

on (startup):
if (start_switch) = "on" AND (coolant_temp) < 120 deg F
then
inject additional fuel quantity for 10 seconds
and
run starter
end if

or

if (start_switch) = "on" AND (coolant_temp) >= 120 deg F
then
inject standard fuel quantity
and
run starter
end if

But for some reason, this particular specimen can't figure out that it's
already warm, so it dumps more fuel into the engine than the engine can
use, and floods it out.

shouldn't make any difference on a fuel-injected car;there's no
"accelerator pump" to shoot more gas into the airstream.

Or the main relay has cooled enough to work again.

I don't believe that the change in fuel would be that significant,to flood
it out.(At temps other than winter conditions)


It's sounding more and more like the main relay.
Your other post says you have spark.

You say if you pushstart the car,it starts and runs.
The ECU would not know that,the starting mixture would be the same as if
you cranked it with the starter.
If it -were- flooded,pushstarting it would be no different.


Of course,removing and resoldering the relay is fairly easy and doesn't
cost anything,and ELIMINATES it as a problem.
You seem to be resisting this.

dude, you don't "pump and pump" to hot start a potentially flooded
engine. you press the pedal to the floor and keep it there while you
crank. that tells the ecu to /not/ inject to clear a recognized
no-start condition.

it's a little more complicated than that, but if you really want to
know, look up the open source injector code for "megasquirt". "google
ees yor frien'."

dude, fix the main relay, then come back and tell us if if your problems
persist.

dude, you don't "pump and pump" to hot start a potentially flooded
engine. you press the pedal to the floor and keep it there while you
crank. that tells the ecu to /not/ inject to clear a recognized
no-start condition.

that is an intermittent problem! exactly like a main relay.
