2000 kia sephia fuel pump/overheating/not turning over


sorry to tell you but you have a blown headgasket or cracked cylinder head. that is why the coolant blows out of the radiator and the engine won't start due to engine compression getting into the cooling system.

Driving my 2001 kia sephiaall sudden hardly was going 30mph..then when got to hwy..same thing and no matter what gear(5spd)would not accelerate.ck engine lite had been on for awhile and our mechanic said...


HAVENT SEEN VERY MANY PROBLEMS WITH THE FUEL PUMPS ON THESE PARTICULAR VEHICLE . YOU CAN TAKE THE 02 SENSOR OUT AND CHECK BACKPRESSURE WITH A GAUGE OR YOU CAN TAKE THE CONVERTER DOWN JUST 4 NUTS AND SEE IF YOUR ACCELERATION IMPROVES . BUT YES A CAT CONVERTER CAN CAUSE A VEHICLE TO BE SLOW TO ACCELERATE AND KEEP IT FROM GOING TO HIGH SPEEDS DUE TO THE BACKPRESSURE ON THE ENGINE . IF YOU TAKE IT TO A MUFFLER SHOP IT SHOULD RUN ABOUT 200.00 TO REPLACE WITH AN AFTERMARKET . IF YOU HAVE A PO420 IN THE COMPUTER FOR CHECK ENGINE LIGHT THAT IS THE LIKELY CAUSE THIS VEHICLE HAS 2 CATS A WARM UP CAT AND A MAIN CAT IT COULD BE EITHER OR BOTH .
