i was driving to my gfs house today and my car was bogging out a little bit, then cel light came on.i checked it out, code 43=fuel supply system.

well i drove to the mall, it was bogging out again..and almost stalling, then when it stopped bogging tons of white smoke blew out

then when i finally park the car, it was bogging, i tried to give it a rev, loads of white smoke again, then stalled, now it wont start

any ideas??

stock 92 dx btw

head gasket... common problem with the civics, mine went last year. If ure handy with cars, do a search on how to replace it. Its been covered before

mattharper

bah....
i hope thats not what it is

the car used to bog out in the rain before but never a CEL btw

imported_kIeRaN

well usually lots of white smoke means that u are burning coolant, the reason that is because the coolant is getting through the head gasket so replace that shizzle on up, took me a day

How would this problem be a headgasket? Please dont comment unless you know what your talking about.....


This code indicates a problem in the cars fuel system.

First off, start with checking fuel pressure. Sometimes a faulty Fuel pressure regulator can cause the ecm to throw this code.

oops, my bad Just thought that it was head gasket due to all the white smoke which is what happened to mine

mattharper

well if its a head gasket, im not fixing it, its going in the garbage and a b18c is going in

mattharper

anyother ideas?

Sure it wasn't filled up with Diesel?

mattharper

lol, i hope not, last time i filled up was like a week ago at a full serve station:S

at first it was just acting like it has every time it rained for the last few months

First check and see if you've lost coolant.
Antifreeze has a sweet smell when it burns, so there should be some clue if your ever able to smell the smoke.

Pull the spark plugs and check the condition of each. By comparing them you'll be able to tell how the car is running and if it is a headgasket/coolant burning issue, you'll be able to tell by the condition of the spark plug.

Next as 1sloweg said, check the fuel pressure. Things to check would be the fuel pressure regulator then the fuel filter.

With my old engine, I had a headgasket go south and there was no white smoke out the exhaust. It just ended up pressurizing the coolant system(not a good thing). With the problems your describing (bogging) along with the ECM code it's throwing, it does sound like a fuel supply problem. It's the white smoke that has me confused. If your able to do a compression check, that should tell you if the head gasket is pooched. Feel free to PM if you need more info.

BTW, diesel in a gasoline engine will billow white smoke out the exhaust IF it does run. Quite funny to watch I must say...

well i just got home form work, while i was there my gfs dad and uncle worked on it, it starts not but sounds pretty rough.. i havnt driven it yet and i dont know what they did to it cause theyre asleep, but ill post up an update tomorrow morning.
thanks for all the info trackhack:thumbsup:

mattharper

now throwing code 3-map sonsor and code 6-water temp sensor


i looked under the hood, looks like a new cap, still havnt talked to my gfs dad

could it be water in the gas? that might cause a fuel system error, white smoke and a bogging effect...

Just another thing to think about..... Ive heaard of bad gas horror storys. especially this time of year

mattharper

what about water coming in through the intake???
i have a cold air intake but no pasenger side fender liner:S

imported_trackhack

No passenger fender liner + CAI = Wet CAI = Bogging in rain

That seems simple enough doesn't it?

If you hit a large enough puddle which you might have ingested enough water into the engine to make it do the things you describe. You might have drowned it.

Pull the plugs and crank the engine over a few times. grab a flashlight and look down into the cylinders, make sure there is no water in them. Even blow then out with some air. If the engine has ingested water, make sure you change the oil.

First thing you should do before you put the car back on the road, get an inner fender liner at the very least.

mattharper

so you think thats the reason for the car dying?

and what to do about all these codes? could the water have fried the sensors causing the car to runny poorly?

imported_trackhack

I'm probably not the only one here thinking that ingesting water into your engine is probably not a good thing. As for the sensors, water on them doesn't help their cause.

If it were my car I'd clean the air filter, put your stock intake back on for the winter if you have it and get that water out of your engine. From there if the car runs you can pick on the sensors and "problems".
