I have been having this problem for the past couple of days. It only happens when I let the car sit overnight, or in the parking lot all day at work. When I turn the key on, the fuel pump runs for 2 seconds. When I crank it, it does not start. If I cycle the key, the fuel pump always runs for 2 seconds. This morning, it started the second crank attempt. When I came home from work, it took 4 tries. Please help! I thought it was the cold affecting the FP relay, but the pump always runs when it is supposed to. Maybe it is the TFI module. Almost forgot, this car has an Accel 300+ ignition box and coil on it. But I guess that doesn't matter because it still wouldn't run if the TFI or dizzy pickup were going bad. I will try to pull codes later tonight, but I don't expect to find anything. I know a lot about cars, and Mustangs in particular, but I won't have time to diag it for a couple more days. Thanks for your help!
