2003 Chevy trailblazer inline6 in august my service engine light came
on took it in they said the thermostat code was showing anyway back
then when I go from place to place when I go to start it , it acts like it
was flooded and took 3 or 4 tries to get it started , I just got it back 2
days ago, had therm replaced and that’s not the problem, it's still
doing it if not worse I tried to explain how it starts and they just say
they can't promise this is the problem, it starts right up in the morning
or after it has sit for awhile but to keep starting it like going Christmas
shopping it does it. It idles good runs good heater works great hope
this is enough info thanks

Answer: Does the check engine like keep coming on still? If it does
when you're having the starting issue, there is still a problem. You'd
have to get it checked out again to see what trouble code is present.
But offhand, you could have a couple different things causing your
problems. It could be something as simple as a clogged fuel filter or
dirty air filter. You could also need the fuel injectors cleaned and
possibly the throttle body cleaned out as well. There gets to be a
build up of carbon inside the throttle body and that greatly affects how
it starts and runs. If you run cheap gas, that can also lead to
excessive build up and hard starting. If the vehicle has a lot of miles,
you should consider a tune up too. If there is any smoke out the
exhaust when started, that will also tell of a problem. Fuel injected
vehicles usually don't flood out unless there is a drastic problem
which would be happening all the time, which in your case it isn't. And
your previous thermostat code does cause a Driveability issue when
the engine computer can't tell how warm or cold the coolant is. If that
code wasn't cleared after repairs, it can still run bad due to it.
