flooded fuel pump
i need help how to resolve this problem. My honda accord is getting flooded and wont start. I dont know why. I just recently had my water pump fix and dont want to spend more money to fix this. I had my timing belt change, filter, oil, distributor,sparkplugs but it still seems to be flooded. I dont know what is causing the problem. Any help would be appreciated.

Re: flooded fuel pump (rob_honda)
What year and trim is your car? Does the motor turn over when you turn the key? Who told you that the car was "getting flooded" and why did they come to that conclusion? How long has this been going on? (Is the problem off and on or did you just wake up one morning and the damn thing would not start)

Re: flooded fuel pump (LookingForVTEC)
the year is 94 honda accord dx .The engine is flooded cause you can smell gas and the spark plugs are wet. I had this onging trouble fordays. When i dry the plugs the car will start. Yes the motor turn over when starting and it is off and on.

'''When it floods, is this during warm or cold engine starts?"""

Not the day's temperature... the engine's temperature.

Re: flooded fuel pump (rob_honda)
In that case, you may want to check out the TW (water temperature) sensor. Its not the same one that sends the signal to the dash temp gauge though. Not sure, but the TW sensor may be located just below the distributor on your engine. Around $35 for a new one.
When the TW sensor goes bad, the resistance the ECU sees is a lot higher than it should be for a warm engine. As a result, the ECU thinks the engine is cold and delivers too much fuel causing your flooding.
The TW sensor is a variable resistor that start high when the engine is cold, (maybe 300 ohms), and slowly drops as the water temperature increases, (to around 200 ohms). I don't recall the exact specs, but you get the idea. If you have a volt/ohm meter you could remove the TW sensor, connect the meter leads to it, and dip it into boiling hot water and then into cold water. The readings should sweep smoothly and gradually from low to high (hot to cold). If it jumps to infinity for even a brief time, you've got a bad sensor.
But one simple thing to check first...
Make sure there is no air in the cooling system. An air bubble can cause the same effect as a bad TW sensor if the coolant isn't contacting the sensor.

Th TW sensor doesn't have any thing to do with the cooling fans.

Have you checked the TW sensor yet?
