Question about 2004 Toyota Sienna

My 2000 Toyota Sienna cannot start in the morning/cold engine

It won't start up in the morning/cold engine. When I put down the gas pedal, it starts right up but when I let it as idle, it will stop. When the engine is warmed up the problem is gone?
Any suggestion please, advise
Best Regards

My 2001 Sienna has the same problem and my friend working in car shop said it needs a new idle speed motor. That is a typical issue for Sienna and Camry. It will cost you about $300. I am call him to order that part today.

Good luck.

First start any day is a nightmare. My 2000 toyota sienna hardly starts the first time i try to start. after going around, there is no problem starting. Any advice what is wrong?


Might be fuel pressure leakdown. Try turning the key to RUN for about 3-seconds, but not START. Then turn to OFF. Repeat 3 times and then try to start. If it starts, you have a bad check valve in the fuel pump that's allowing fuel pressure to drain down overnight. Replace fuel pump.

If that doesn't work, try depressing the gas pedal halfway while cranking the engine. If that helps, check out the engine coolant temp sensor. A sensor that's out of calibration will send bad info to the computer and the computer will provide too lean a mixture for a cold engine. Depressing the pedal overrides the sensor and the computer adds gas.

Cold start cranking problems 1987 toyota truck wont hardley crank when cold then fires fine after gets crunk till next morning


My 1987 truck I use to have had a choke and it would stick open some times. When you get in the vehicle, you have to press the gas pedal to the floor once to set the choke and add enough fuel to start the vehicle. I assume your vehicle has a carburetor and would suggest the following:

When your engine is cold, take off the air cleaner cover and base and look the butterfly valves. They are fist valve on the top of the carb air inlet. Go and step on the gas pedal once. Observe if the valves move to the almost closed position or not. If they don

Sounds like the spark plugs. I would recommend replacing them and see how it acts. If it doesn't change anything, leave a comment and I will give you some more suggestions, but I would start there.

VSC Trac off lights on dashboard


I have just had the same problem this morning for the first time and I suspect it is just bad gas. We have had problems with the check engine light in our camaro whenever we bought hi test at the Mobile gas station closest to our home. I would not be surprised if this same gas station is now having water problems with their regular gas which is what we put in our 4runner. Try STP gas treatment first, which is what I am going to do now. When I used this approach with my camaro, the light went out within a few days. Technically, a sensor might have been damaged, but my thinking is that if that sensor is dead, then my fuel/air mixture will get bad enough to notice pretty quick. The TRAC off and VSC off are just extra lights that go on, whenever the check engine light comes on. I'll let you know how it goes.
