[QUOTE="scott degroot, post: 855842, member: 66039"] Richard Do you have a natural gas vehicle?? That is the only way a 2001 ST would be equiped with a fuel rail pressure sensor. WITHOUT THIS SENSOR IT IS IMPOSSIBLE FOR THE PCM TO KNOW WHAT THE FUEL PRESSURE IS AND THEREFORE IMPOSSIBLE TO DISABLE THE IGNITION DUE TO LACK OF FUEL PRESSURE....that dog don't hunt(I love that saying) I think your "dealer mechanic" got one over on you, and if your fuel pump runs longer than 2 seconds than so be it, every Ford that I have ever tested that has an intank electric fuel pump, the pump will stay energized for approx 2 seconds when the key is turned on, now if you try to start it they will stay energized for a bit longer if you release the key wothout shutting it off.
