Flood at start and general over rich condition

This is a 2002 chry. t&c w/ a 3.3. when I start it in the morning cold I have to press the pedal to the floor to start it as it is flooded. It runs nice and smooth when warmed up but has a serious rotten egg smell to the exhaust and fuel mileage went way down, it just started to do this. It has always run good otherwise and got real good mileage. Any suggestions would be deeply appreciated as I can't really afford to take it to the garage for troublshooting. I'm capable of fixing if I know whats wrong or what to check.     thank you very much........John

My 02' Nissan altima stalls when its cold. But


It is probably the "cold start" cycle. A Temperature sensor will send a signal to the computer in order to make the fuel charge rich and change the timing. This will last less than 3 minutes on many cars.

The process is similar to the old "choke" system adding a timing change to the rich fuel mix. Many cars have 2 Temperature sensors and for those you want to change the one that does NOT work the dash gauge or light. The sensor you want is dedicated to providing temperature info to the computer.

Please rate my info.

Floods when cold


Define flooding.

  1. Black smoke out of the tail pipe?

If the fuel return line is plugged,it will flood.If the fuel pressure regulator has lost its vacuum signal ,it will flood.

If there is a large vacuum leak,the O2 will see a lean condition and cause the rich condition.gas mileage will suck,big time.

This "flooding" happens when the engine is cold? ONLY?
Be sure the air filter is not clogged and the PCV is not plugged up solid.
Also,there are a few tubes from the valve cover that vents oil vapors into the air filter housing.

During this flood mode,hold the pedal to the floor and shut the engine OFF-it should NOT keep running.(Leaky injectors)...

Do this when engine is hot and cold.

Won't start when cold. pump gas an it starts but smells rich an hesitates. once warmed up runs good.


You may have a temperature sensor issue. Hook up a live data scanner and it will tell you if this is your problem. If your temperature sensor fails, it will tell your computer that it is below freezing. This will cause the computer to add more fuel, and it can "flood." By pressing the accelerator, you actually cut back on the fuel delivery. Have this looked at.

Experienced recent cold weather. Car will not


It's flooded like you say.
If it's really flooded, you'll have to remove plugs and dry them off.
Install them.
Now when you crank engine, hold gas pedal to floor.
That will stop gas from spraying into engine.
You need to get the gas out of the engine for it to start.
Crank for 20-30 seconds with pedal to floor. Do this 3 times waiting 2-3 minutes inbetween cranks.
The starter needs to cool down.
Then after that start normally and see if it will start.
Remember if it will not start after 2 attempts, then the possiblity of it flooding is there and you'll have to clear out the gas by holding the pedal to the floor again.

Ensure your spark plugs,wires (ignition coil and spark) and your filters (air and fuel) are within 2 years of installation It's erratic at 800 rpm as the engine is cold and they like the 2200 range for 3 minutes before they kick down on their own. Press the pedal twice before inserting your key. The owners manual states depending on the outside temperature, the engine will require more priming. Update if possible.

2002 odyssey injectors flooding


The owner's manual offers these tips on starting in cold weather. First, do not touch the gas pedal and crank the engine for no longer than 15 seconds. If no start, hold the gas pedal halfway down and crank for no longer than 15 seconds. If no start, hold gas pedal all the way down and crank for 15 seconds. If no start, hold gas pedal halfway down and crank for 15 seconds. During any one of the start attempts with the gas pedal part/all the way down, if the engine should start, slowly release the pedal so the engine will not race. Remember that fuel does not atomize as easily in cold weather and can be a problem.
