I have a 96 Sable it overheated and stalled. After about 2 hrs. to let it cooldown it still would not start. Had the car towed home and checked for codes. The only code on there was P0117. I changed the coolant temp. sensor and the temp. sending unit. Checked fuel pressure its at 40 . I also have spark. The plugs in the front are a litte wet ,but and soaked with gas.Any ideas
