Check engine light comes on after fueling car

Seems like an accelerator pump is worn out in the carb.To check it take off air cleaner and pump the throttle body by hand and see if it squirts in the top of the carb with engine off.Or bad fuel filter.

Catalytic convertors' been bad for ten years?!! They're probably plugged.

This is my drive cycle a generic drive cycle i have used many times over the years and it has never failed me most drive cycles are too specific and impossible to adhere to for most drivers follow these steps exactly 1. make sure all codes are cleared and no check engine light is on 2 make sure the fuel level is between 1/4 and 3/4 full (this is part of the enable criteria for the evap monitor to run ) 3 let vehicle set overnight 4 start engine and let idle until the temp gauge is in the middle (this cold start enables the evap monitor and runs the O2 sensor heater test )5 drive vehicle around town avoid the highway stay at below 50 mph and when stoping at lights remove your foot from the gas and coast from around 50 to about 10mph or less if possible this will run the EGR monitor after about 3 to five miles of this proceed to the highway or freeway and travel over 50 but under 70 mph for about 3 to 5 miles this will run the catalyst test provided the O2 monitors passed if they didnt you will have a check engine light on before this point also i do a coast down on exit ramps (no braking) they make great places to get that EGR to run ONCE YOU START THIS PROCEDURE DO NOT KILL THE ENGINE OR SOME OF THE TEST WILL FAIL TO RUN

the small things can a big issues. you are like you do not blow the head gasket or engine from over heating

no its not the fuel pump, filter maybe... cant see why though.

You'll have to figureout if it is a fuel or ignition problem.Isthe check engine light on ?
It could also be a failed injector or loss of compression on one cylinder.

Try some injector cleaner in the fuel--there might be some water in the fuel also. Check the air cleaner.

you will need to drive about 50 miles till the computer checks the system since it was reset. Your check engine light may come back again, if it does run a vacum test..

sounds like a fuel filter or more likely a fuel pump fault.low fuel transfer pressure,possibly a dealer would be cheaper than a diy repair unless you have the diagnosis correct.

how much oil is left in the engine ?
the smoke was probaly oil burning,the knocking could be from low oil pressure,this could be very bad.check the oil and coolant levels and repost and let me know how they are.if any oil shows on the dipstick smell it and see if it smells burnt.
