I have a 99 GT with 69,000 miles, recently, in order to avoid a collision, I swerved into a curb. Later in the day while shifting into third gear, my car fell on it's face, and would not respond. The check engine light came on very quickly. I had the car towed to a shop. It was there 6 days. They replaced the ECM, the fuel rail pressure sensor, and the IAC valve. They reloaded the SCT program onto the new ECM, and the car made 401 HP at the rear tires, on a Dyno Jet. 1600 dollars later, I pulled out, and... It stumbled and died again. The pcm codes are P0190; and P0193. These point to a Intermittent short or open, in the Fuel rail pressure sensor, which was replaced. The voltage at the connector is 4-6, normal. Is it possible, that the fuel pump, or a device controlling it, is at fault? It seems to have low pressure at the rail, during the stumbling periods. For a car that has always been reliable, I am afraid to drive it now, because of the towing charges. It is in the garage now, while I try to decide what to do. I don;t want to go to the dealer, pay a ton again, and have the problem resurface. Has anyone else experienced this anomoly? Thanks.
