Check this out!
A lady at work has a 1999 Accord. I don't know the mileage or any thing like that I do know she has to have the strangest car problem I have ever heard of . For about he last two months, after she fills up with fuel the car won't start she has to wait a few minutes and them it will start. But she says it runs kinda ruff, like it doesn't want to accelerate then it will start running okay untill she puts more fuel in it.

I told her to just leave it running while she fueled up. She said she tried that and the car will actually go dead while she is putting the fuel in.

Other than that she says it runs fine.

She did have to have all of the Vapor system (under the car) replaced, she drug it off. And the stealership talked her into buying a new engine instead of replacing a leaking head gasket. And she said she had the Cat. Converter replaced. And there is a check engine light on but I do no know the code.


Any help would be greatly appreciated

oxygen sensor, she can put the peddle on the floor and there is no exceleration.

you need to scan the computer to get the code #'s

Thank for the replies. I talked to the owner again last night, she did say that when she had the codes pulled had a cat. conv. code or something similar. I was going to pull the codes but wasn't sure which teminals to jump on the plug. Also I found a thread on reseting the ECU/ECM memory but her car did not have a memory fuse. I think hers is labeled as a CLOCK fuse? I wll look some more and see if I can find any threads. Thanks again

99 is DTC II compliant. She needs to go to Autozone. They will read her codes with the scan tool for free.

I have no new information on her car. I tried to pull the code by jumping the pins but the MIL did not even flash once. I know there are some codes that are not going to show up by jumping the pins. I reset her computer and told her to watch for the check engine light to come on( pay attention to what the car is doing). Then I told her to go to Autozone or Advance and get them to pull the codes and get a print out. I think that is all I can do for now.:runaround:

Still I don't know what would cause a car to die when you put gas in the tank??? I am leaning towards a faulty fuel level sending unit or even a bad computer (internal circuit problem). WHO KNOWS???:screwy:

Hey if it only dies when you put gas in it... don't put gas in it.:iceslolan

Sorry for the delay. The lady at work finally got back with me tonight. She took her car to autozone or advance and got them to pull the codes.

The only codes she said it showed was
P1457- Manufacture Control / Auxillary Emission Control

I am not sure what this means and how it would connect putting gas in the tank to the engine dying. Once again any help is appreciated.

Sounds to me like someone has to get under the car and check to see that the evaporative system hoses and components were properly installed- a vacuum line may be taking in raw fuel, which would cause the condition you're describing.

DING!

Good call...something is misrouted or kinked in the evap emissions system at the tank.

PS don't try jumping pins to get DTCs on anything built after 1996...at best you'll get nothing, at worst you'll burn the ECM.

They are OBDII, need a scan tool to code....

Well I could alomost believe it was taking in raw fuel except that it is hard to start after you put fuel in the tank with the engine off. If you gas up with the engine off how would the fuel be sucked into a vacum line? Why does it not suck fuel into the line when you are driving?

I will tell her to get the evap system checked out. Thanks for the help

There are solenoids that close some vacuum paths and open others when the ignition is off, to allow expansion/refueling vapors to be pushed into a canister. When the motor is started again, that solenoid is supposed to close, and another opens, allowing the canister to purge to the intake.

But when things are misrouted, kinked, or a solenoid fails or sticks open, you can end up with either liquid fuel rather than vapors being drawn into the intake, or a massive vacuum leak, which can also make them run weird.

For example the purge solenoid should open while cranking the starter, then close when the engine begins to run....if it sticks open, the motor will not run right until it closes

If the return condensate line on the canister is hooked to the purge side, it'll pull raw fuel rather than vapors after filling, etc....

Anyway, good chance the code may tell you exactly what is happening. Ususally they will code when a solenoid or mechanical tank vent is failing...
