HELLO NEW TO FORUM BEEN HAVING A PROBLEM THAT I CANT NOT SEEM TO FIND, REDAY TO JUST GIVE UP AN SEL CAR BUT I FEEL I AM CLOSE AND ITS PROB JUST SOMETHING DUMB THAT I HAVN'T CHECKED, WELL I HAVE A 1990 TOYOTA COROLA GTS WITH THE 1.6L 4AGE ENGINE THAT EVERYONE WANTS, AND I BOUGHT IT AS A NON RUNNING VEHICLE FROM PREVIOUS OWNER, TOOK A LOOK AT CAR ONCE AT MY PLACE AND FOUND THAT THE SPARK PLUGS WERE FOULED AND WET OF FUEL. CLEANED THE SPARK PLUGS AND VEHICLE STARTED RIGHT UP AND RAN GREAT FOR WEEKS. THEN ONE DAY SAME SYMPTOMS NO START RUNNING RICH BLACK SMOKE FROM EXHAUST AND FOULED AND WET SPARK PLUGS, SO I TEST THE FUEL IJECTORS AND FOUND 2 OUT OF THE 4 WERE LEAKING, REPLACED ALL FOUR INJECTORS AND O2 SENSOR AND GOT NEW SPARK PLUGS VEHICLE RAN GREAT FOR A DAY, DROVE VEHICLE 20 MILES AND CHECK SPARK PLUGS THEY LOOKED GREAT NO WET FUEL OR CARBON BUILD UP AT ALL, WAS GETTING READY TO DO EMISSIONS TEST AND THE UPPER HOSE ON RADIATOR CLAMP CAME OFF LOST SOME COOLANT BUT DID NOT OVERHEAT AT ALL, GOT IT BACK TO MY PLACE CAUSE EMISSIONS SAID FIX LEAK BEFORE WE CAN TEST AGAIN, MADE IT BACK FILLED UP COOLANT AND FIXED THE CLAMP THAT FELL OFF AND NOW VEHICLE WONT START, CHECK THE PLUGS AND I SEE 2 OUT TOF THE FOUR LOOK MORE FOULED AND WET THAN THE OTHERS, I AM BEGINNING TO SUSPECT THE COLD START FUEL INJECTOR, I FORGOT TO METION WHEN I CHAGNED THE INJECTORS I UNPLUGGED THE COLD START INJECTOR AND LEFT IT UNPLUG ELECTRICAL BUT NOT FROM FUEL SOURCE, THE WEATHER WAS GETTING COLDER TODAY AS THE DAY WENT BY COULD IT HAVE BECOME STUCK OPEN ONCE ENGINE HEATED UP OR BUILD FUEL PRESSURE? EVEN WITH OUT AND ELECTRICAL SIGNAL TELLING IT TO OPEN/CLOSE, NOT SURE WHERE TO GO NEXT OTHER THAN THAT NEED SOME DIRECTION.
have not looked for codes, this is pre obd so i can not hook up scan tool and tell everyone fuel trims or anything, i will try connecting the pins and seeing how many time the check engine light flashes and see what codes are stored, but still need some guidance
YES I HAVE SPARK, THE PLUGS GET FOULED WITH CARBON AND WET WITH FUEL THEN DONT IGNITE ANYMORE, CAN ONLY RUN CAR FOR SHORT TIME BEFORE THIS HAPPENS, SO DONT GET A VERY LONG TESTING PERIOD, VEHICLE IS RUNNING SUPER RICH CONDITION
Definitely easier on the eyes to not type in all capitals. Thanks.
As for your car. If you spark is good and you're continuing to flood the engine out, you need to start focusing on your critical inputs. ECT being one of the main ones.
