My 2003 sentra does the same thing and I have come to learn from other sentra drivers that its just something the sentra does. I have noticed that it will crank right away if you have the air/heat off and you press the break when cranking. Sometimes it even helps to continualsy pump the break to make sure it stay cranked.

    Sounds like you are having vacuum line problems. The only connection between the brake and the engine idle is vacuum, as far as I know.

I have a Nissan Altima 99 than spend a lot of gas wath I can do ?


Dirty air filter

Dirty injectors + o-rings

Vacuum leak at intake manifold and vacuum hose.

Bad Idle Air Control Motor (IAC)

Low compression (170 psi + is OK)

Start cleaning and repair these trouble spots and see is there any improvement.

====

For more advance DIY'er then you may try this.

Use a can of Berryman carburetor clean to locate the vacuum leak.


SEE SAMPLE PICTURE HERE


This is a 20-30 minutes job.

Vacuum leaks can occur in following locations.


Intake manifold AND/OR vacuum lines.


Intake manifold is not accessible unless the engine head if off.

You can still check the potential leak by spraying some Berryman near the intake manifold.

Listen for rpm increase after you introduce the Berryman (FUEL) at idle.


Do the same starting from the brake booster unit (the round unit) on the drive side fire all.

Carefully listen for increase of RPM right after to spray the Berryman to the potential vacuum spot.

Get a friend to HEAR the RPM increase or monitor for RPM on the tech.

DO NOT AIM the Berryman into any heat source.


PLEASE RATE my answer if it is useful to you.

apply a light force to the gas pedal and start the car continuing to regulate the rpms with gas pedal if you can make the car idle with the gas pedal then you will probably need a new idle air control valve

Starting trouble after i let it run out of gas


Sediment from the bottom of the tank could be blocking your fuel filter. Replace your fuel filter.
