It sounds like your fuel injectors are leaking.I had the same trouble,the #3 cyl would fill with gas.The car would start and run after blowing all of the gas out of #3.Mark

i replace the injectors with some from the junk yard and the same problem.i will try the coolant temp sensor.i try to check for a code in the computer,i turn the key to the ignition and the light on the computer stay red (no flash).shouid the light flash???

[Oldblueaccord]

Yeah the light should flash blink the codes. A solid light may mean a bad ECU. I think also there is a ground wire asscoiated with the injector hold downs that is very very important. I think it is a loop lug that goes under the fuel rail or the nuts and studs. If the injectors are fully ground they prolly just dump fuel with the key on.

Also our injectors have the resistor pack,sliver box on the drivers side, alot of cars do not.

do you have a pic with that wire??.is there a test to make sure it is the computer?.thanks

i just went to the car took the drivers seat out,remove the plastic cover over the computer and what i found is that the computer had got wet and some of the terminals are rusted.so i will be going to the junkyard this weekend.thanks for all your help.hopefully i will be running this weekend.

is there a test to make sure it is the computer?.thanks

Yes. Honda addresses this frequently in their manual: "replace the ECU with a known good ECU." If the problem goes away, it was the ECU.

Great test, eh?

update!!.replace the ecm and she runs.after the car warms up it wont idle.check the code.it is a code 9.its crank angle sensor.so i will play with that later.

[Oldblueaccord]

Let us know if it continues to flood. That does have something to do with your injector pulse width I think. Good find on the ECU getting wet. Might want to mount it up off the floor until you can find the leak.
