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.

Crank no start ,got fuel got spark, when trying to start spark plugs get wet ,changed plug pinched fuel line shut try srarting flud wont start???


You pinched the fuel line????
If you crank for too long to start the car, the engine will "flood", this is why the plug was wet. It had too much gas and wouldn't start.
Pull out ALL plugs and dry them off.
Install them.
HOLD your gas pedal to the floor and crank.
This will stop gas from entering the engine.
you need to get that extra gas out beofre it will start.
If you have so much gas in there you can do damage to your engine!!
Now after a few crnaking attempts with your foot to the floor, take your foot of the gas pedal and try to start it again.
But remember if it doesn't start in 3 tries, you need to do the pedal to the floor once or twice to remove the excess gas.
When you crank the car to start it sprays gas into the engine, even if it won't start. So it very easy to "flood" the engine, and then you'll have a hard time to get it going!

The car has full electric powers but it wont turn over. what's the problem


Just because the lights go on and the radio plays does not mean you have full power.
Many things can keep a car from starting, and the cold makes them worse.
Did you try jump starting?
And most importantly did you crank the engine for maore than a minute at a time? That means you have flooded the engine with gas.
To fix this, jump the car while holding the gas pedal to the floor. Do this 4 times at 20-30 seconds each.
Then try and start without holding gas pedal.

Change the coolant sensor, it is stuck in advanced mode causing the engine timing to be out of sinc. Do not over tighten the sensor. About 5ft.lbs is enough. Good luck!

2002 s-10 have to hold gas pedal all way down to start when it does start sounds like old modle a john deer let of gas moter dies


sounds lie your pressure is ok, but I am curious about the Volume. When was the last time you changed your Fuel Filter? If it is a flex fuel vehicle, and you use a standard gauge on fuel pressure, it will read a bit high.
Second, How old is your battery? Mine did the same thing over the winter, and I found out that my 2000 S-10 only had one replacement battery 4 years ago. It didnt have the Cranking Amps it needed , resulting in hard starts, and low voltage to the Spark Plugs, which made it run rough.

It takes a few seconds with the gas floored to get it going. once it is warm it starts fine. I did smell a faint gas smell a week ago. it has 50k miles on it. wondering what it is and what it should cost


Possibly a leaking fuel injector(s). When you floor the gas pedal when cranking it puts the computer into clear flood mode which shuts off the injectors.

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.
