I have a good running 94 Taurus GL 3.8l...when it runs. I can drive it for five minutes or five days then engine quits...no fire. I let it set for a while, sometimes a whole day and she starts right up. I only have one code..EGR valve. I'm not overheating and getting plenty of fuel pressure. I've replaced the ignition module, PCV, coil, and distrubutor pickup(was not easy). If anyone can give me input other than the brain please send it my way.
