93 Buick century will quit?

If the car restarts after 15 - 20 min then most likely it's the fuel pump. If not it's the computer or crank shaft sensor. When the fuel pump starts to go you may hear a high freq noise from the rear.

I HAVE A 93 CENTURY AND IT COST ME A FORTUNE BEFORE I FOUND OUT WHAT

THE FAIRLY SIMPLE PROBLEM WAS . AS I DROVE THE CAR WOULD JUST SHUT OFF

AS IF SOMEONE SHUT OFF THE IGNITION . SOMETIMES IT WOULD START IN A

FEW MINS. , TAKE A JUMP , OR EVEN GO DAYS WITHOUT BEING ABLE TO START IT .

AFTER A GREAT DEAL OF RESEARCH , I DISCOVERED THAT IN THE 92 AND 93 CENTURY

THERE IS A PROBLEM WITH THE CRANKSHAFT POSITION SENSOR . BUICK IS AWARE

OF IT BUT NEVER RECALLED IT FOR THAT PROBLEM .

WHEN YOU START YOUR CAR , OR ARE DRIVING IT , THAT CRANKSHAFT POSITION

SENSOR IS TELLING YOUR PLUGS WHICH ORDER TO FIRE IN . IF IT DOESN'T GET

THE RIGHT SIGNAL TELLING IT WHAT TO DO THEN IT SHUTS DOWN .

IT IS ABOUT A $35 PART . I HAVE HAD TO HAVE MINE REPLACED TWICE IN 7 YRS .

I HAD IT MISDIAGNOSED AS A BAD BATTERY , BAD ALTERNATOR , BAD FUEL PUMP ,

BUT AFTER SPENDING ALL THIS MONEY FOR THE MISDIAGNOSIS OF THE PROBLEM

IT WASN'T UNTIL I DID MY OWN RESEARCH THAT I FOUND THE ACTUAL PROBLEM

MYSELF . A DIAGNOSTIC MACHINE WON'T FIND IT , BECAUSE IT'S INTERMITTENT .

SPECIAL NOTE SO YOU DON'T GO NUTS LIKE I DID . ON A 92 CENTURY A SPECIAL

TOOL TO ADJUST THE SENSOR ONCE REPLACED IS REQUIRED . ON THE 93 CENTURY

IT IS SELF ADJUSTING ONCE INSTALLED . I ALSO RECOMMEND VERY HIGHLY

YOU INVEST IN A HAYNES MANUAL FOR THIS YEAR AND MODEL OF CAR . I GOT

ONE ON EBAY , BRAND NEW FOR LESS THAN $5 . IT WILL SHOW YOU EVERYTHING ABOUT THE CAR , AND INSTRUCT HOW TO REPLACE SENSOR .

THE PROCESS OF CHANGING IT ISN'T ALL THAT DIFFICULT , THE HARDEST PART

ABOUT IT IS GETTING TO IT . BUT EVEN THAT ISN'T THAT BAD ONCE YOU KNOW

WHERE IT IS ON YOUR CAR ( PASSENGER SIDE , BEHIND WHEEL , AND PULLEY)

I WISH I COULD HEAR BACK FROM YOU TO FIND OUT THAT I HELPED SAVE YOU

LOTS OF MONEY , TIME AND HEADACHES . NOT TO MENTION THAT IT MIGHT

SAVE YOU FROM HAVING A SERIOUS ACCIDENT WHEN THAT DARN THING CUTS

OFF WHILE YOU'RE DRIVING . MINE BROKE DOWN ON THE BUSIEST STREET IN

TOWN @ 4 PM . AND I HAD I DON'T KNOW HOW MANY CARS ALMOST HIT THE CAR .

I HAD GOTTEN OUT OF THE CAR BECAUSE I KNEW IT WAS IN A VERY DANGEROUS

PLACE AT A DANGEROUS TIME . A CAR CAN BE REPLACED , MY LIFE CAN'T .

BEST OF LUCK TO YOU . I'M NOT A GAMBLER BUT ON THIS I WOULD WAGER

I AM RIGHT , SINCE I'VE HAD THE SAME PROBLEM . A MECHANIC WILL TELL

YOU THAT IT CAN'T BE THIS PROBLEM , THAT THE SENSOR WILL NOT CAUSE

THE CAR TO FAIL TO START , OR CUT OFF ON YOU . I AM SORRY TO ANY

MECHANIC WHO READS THIS , BUT YOU ARE MISTAKEN . I MAY NOT BE A

MECHANIC BUT THIS PROBLEM ALMOST CAUSED ME TO GET RID OF A GREAT

CAR IN EVERY OTHER ASPECT .
