1999 Ford Explorer Fuel System Other Electrical System Air Bags Seat Belts Unknown Or Other Problems

WHEN IT IS HOT OUTSIDE, THE CAR WILL NOT START. IT JUST CRANKS AND CRANKS,BUT, WILL NOT TURN OVER.....AS IF IT WAS OUT OF GAS WHEN IT IS NOT. THERE ARE MANY TRICKS TO GETTING THIS THING TO START THOUGH. IF THE WINDOWS ARE ROLLED UP ALL OF THE WAY, AND IT HAS NOT BEEN DRIVEN BEFORE NOON, IT WONT START. IF I DRIVE IT IN THE MORNING WHEN IT IS COOL OUTSIDE, IT WILL ALMOST ALWAYS START LATER IN THE DAY. IF I DON'T DRIVE IT UNTIL THE AFTERNOON, AND THE WINDOWS HAVE BEEN LEFT DOWN AND IT IS PARKED IN THE SHADE, IT WILL ALMOST ALWAYS START. THIS PROBLEM HAS BECOME A NIGHTMARE. I HAVE HAD IT IN THE SHOP 2 DIFFERENT TIMES AND THEY HAVE YET TO FIGURE OUT WHAT IS CAUSING THIS TO HAPPEN. THEY HAVE REPLACED RELAY SWITCH'S AND FUEL FILTER, BUT HAS NOT HELPED. I HAVE NOTICED THE "THEFT LIGHT" BLINKS RAPIDLY WHEN IT WONT START, EVEN THOUGH I HAVE NO THEFT DEVICE ACTIVATED IN THE VEHICLE!!! THE AIR BAG LIGHT COMES ON AND OFF WHEN IT FEELS LIKE IT, THE DRIVER SIDE WINDOW DOESN'T ROLE DOWN HALF THE TIME, AND THE SEAT BELTS IN THE BACK SEAT "LOCK UP" EVERY TIME SOMEONE USES THEM TO THE POINT WHERE WHOM EVER IS USING IT HAS TO TAKE IT OFF AND LET IT RETRACT ALL THE WAY TO GET IT TO UNLOCK. THIS HAPPENS SEVERAL TIMES DURING A TRIP IN THE CAR. I AM OVER ALL DISAPPOINTED WITH THE CAR AT THIS POINT, AND WOULD LOVE TO SELL IT, BUT, I CAN NOT PREDICT FROM DAY TO DAY IF IT WILL EVEN START FOR A BUYER TO TEST DRIVE IT!!!! THE STARTING ISSUE HAS BEEN GOING ON FOR A FEW MONTHS, THE OTHER ISSUES HAVE BEEN HAPPENING FOR ALMOST A YEAR NOW. *TR
