1998 Ford Contour 6 cyl Front Wheel Drive Automatic 221000 miles
My 1998 contour has 221,000 km on it. Recently it began hesitating intermittently and then a few weeks later it began not starting. It will crank but not start. In 5 or 10 minutes it starts no problem. I've had it into the dealership several times and they can't duplicate the starting problem and no codes show up. They have recently replaced the DFPE sensor and I've had a tune up and PCM reprogrammed. When all this work was done, the car worked beautifully for about 5 days and then the intermittent starting issues began again. Any ideas?
