nissan sentra hard to start in hot weather
john.1....@spamgourmet.com
it usually has the trouble-free starting -- you turn the key, no
accelerator pumping, in fact the manual tells you NOT to pump.
however, i found as hot weather encroached these last 2 years, that if
i leave the car out where it's hot, then it becomes hard to start. in
fact, i have to pump the accelerator as if i still had a carburetor.
is there a reason in hot weather for starting to be difficult, and if
so, a remedy? thanks.

it, not ever!
There is no carburetor float bowl holding gasoline, so there is no
reserve fuel to inject into the engine.
You claiming that pumping was needed to start the car in hot weather was
false.
While you were stomping on the gas pedal, the fuel was being pumped up
from the tank.
It would have started whether or not you touched the gas pedal.
If, when starting the car, you pause at the run position for a second or
so on the ignition switch, that will give the fuel pump time to get the
gas to the injectors.
Then you move the key to the start position.

An easy test to see if the fuel pump is being energized is to remove the
gas cap,have an assistant turn the key to 'start' but NOT crank the
motor,and listen at the fuel filler for the whine of the fuel pump.
the pump stops after a few seconds,so you can't just turn the key yourself
and run back to listen.

Not the full story. While rare, it's possible for a fuel injected car
to flood. Could be one or more leaky injectors. The FI system is
designed so that if you push the pedal ALL the way to the floor it
will reduce whatever the normal fuel amount would be during a start to
allow it to start while flooded. So depending on whether his pumping
of the pedal might activate that system it is possible his pumping
helped start the car.

Check your fuel pressure.
I had that problem and it was the fuel pump going bad.

around the fuel pump. i'm not ready to rush in for a big repair bill,
but in response to the first person to reply, it definitely is harder
to start on a hot day than on a cold one. it cranks without igniting.

Well, measure the fuel pressure at the rail and see if it matches what
the manual says.
Did you change your fuel filter when the manual said to?
All kinds of things can reduce your fuel pressure, from a clogged filter on
up. But until you hook the gauge up, you don't even know if it's a fuel
pressure issue.

may tell the engine it is cold and supply more fuel than needed,
flooding the engine. A friend had a corolla with this problem. He
would crank sometimes up to 10 minutes for the car to start. The ECT
was the culprit.
Fuel pump could be a problem but as someone else suggested, fuel filter
is a starting point.
Flooring the gas pedal will cut the fuel supply and will help start a
flooded engine.
Good luck,

You have to have the pedal floored BEFORE turning on the key for that
to work. KB

I to have a 2004 nissan sentra with 160,000+ miles on it and i have also experienced the same problem with the hard start. I have changed the coil-on-plug boots for the spark plugs but that didnt work. it wasnt till recently that i had to work on my car from a minor accedent that i decided to change my fuel pump. the pump was expensive and pretty massive in size do to the fact that its the pump and filter in one unit. after i did that and started using fuel injector cleaner every 3000 miles that the hard start has really calmed down. it has fully gone away but it definitely made a difference so my advice would be to start with the fuel pump.
