Stalls when starting the car

[Jai_Jai_Binks]

For some reason my car stalls when i start the car in the mornings. I park my car outside (no garage space..since other cars are inside!). Also, this happens sometimes and not always, and only in the mornings...when the car was left overnight! Do note that i park on my driveway...and its slightly inclines, and i park my car facing the street. I turn the key, and the starup seems to lack gas/air??? (from the sound)..this happens for the first 3-4 seconds...and then it normal warmup. My car's got about 27K miles on it, and yes its is a 5S-FE. Serviced every 3K miles since new...and right now I am about 600 more miles away from another service. This is what I think could be wrong:
1. my fuel filter is dirty and need to be replaced?? (service will solve that)
2. coolant sensor?? (How could I tell if this is bad/kaput, Autozone???)
3. vaccum sensor (Same like two, Autozone???)

Or is there anything else you all can think off?? Also, anyone in the same boat as me...I know we had this problem in our cressida as well...the way, we solved it was to pump the accel twice before start up, and that worked fine for 170K miles! (hahah). But since this car is under warranty, just wanted to get it fixed!

lately ive noticed my startup is kind of rough too, although it could just be my regular paranoia
it seems like it takes too long for the engine to start when the car hasn't been driven for a while (ie: overnight)

(that's not considered stalling is it?)

Stalling is when you're driving, and the engine inadvertently dies as you're driving or decelerating.

I would think if a sensor was bad you would get the "check engine" light. So maybe we can rule those out? I believe there should be a check valve in the fuel system to keep it pressurized after the fuel pump is shut off, so the engine can start right away. Maybe the check valve is leaking? You could check for fuel pressure in the morning before starting the car. There should be a valve (like on your tire - schrader valve?) on the fuel rail where you could check. Just some thougts...

You're injectors may be dirty, try a gas treatment or use some intake cleaner.

Did you mean stalling like flip described, or the engine just takes for ever to turn over.

If you are having trouble getting it to start it could be the spark plugs are shot. Also your battery could be going dead plus any number of variables.

If the starter seems like it's sticking...in some cases the starter could be going bad...but that's unlikely. Seems like you have carbon buildup in the head more than anything else.

Stalling, as in like this..Turn key to state car...engine does not turn over..but weird noises come...and then all of a sudden, the rev's shoot to 3.6 and then 3 and then its normal warmup! All this is like first 5 seconds of the startup! (yeah, its not normal, as i've got another 5sfe as well).
Sparks that early in the life of a car?? I'll check that! Got the battery check, that was all good there...

How do I check that (is it a diy) or a shop process to check that??

Shop process to do it. It wouldn't be a bad idea to do it anyway.

Your problem description keeps changing. First you say it stalls when you first start it, now you say it doesn't crank then all of a sudden the revs shoot to 3.6 then 3?
Sorry, but it ain't gonna start if it ain't cranking.
A better "problem statement" would help to figure this out.

I don't know the engine LINGO to describe this. when i trun the key, nothing happens (like starting the engine)...nothing but weird noises (like its deprived of air)..hence i said it doesn't seem to crank...but then automatically it shoots up the revs and starts on its own..(w/o additional turn/accel or anything from my side)....Its like i turn the key, and 5 seconds later it starts...the way it is supposed to...dealyed reaction!...Thanks Ryan...I'll get that checked when i get my 30K service done! thanks to all!
