NHTSA Complaint #10068422 — 2000 FORD FOCUS

WASHED CAR AT LOCAL CAR WASH, AND CAR RAN FINE. GOT HOME TO DO FINISHING TOUCHES AND KEPT CAR RUNNING. LOW ON FUEL, A LITTLE UNDER THE 1/4 LINE, BUT RAN FINE. WENT BACK OUT ABOUT FOUR HOURS LATER TO GO GROCERY SHOPPING, AND CAR WOULD NOT START. ALL THE LIGHTS AND DINGING WOULD COME ON, BUT THE ENGINE WOULDN'T TURN OVER. FOR 2 DAYS MY CAR SAT IN THE PARKING LOT NOT STARTING. I WOULD GO OUT IN THE MORNING TO TRY AND START IT, AND IT WOULD ALMOST START, BUT WOULDN'T. I HAD AAA TOW MY CAR TO A REPAIR SHOP AND WHEN IT GOT THERE, THEY CALLED ME AND ASKED WHAT I WAS TRYING TO DO. THEY GOT THE CAR OFF THE TRUCK AND IT STARTED RIGHT UP. THEY ARE KEEPING MY CAR OVER NIGHT TO TRY AND START IT IN THE MORNING. I FEEL REALLY DUMB NOW AND BAD FOR WASTING THEIR TIME. WHAT COULD THE PROBLEM BE?
