Other Fuel System Hoses Lines/piping, And Fittings problems of the 2005 Ford Expedition

1. 2005 Ford Expedition August 8,2010: around 12:45pm I started my car up to run to mcdonald's two minutes away from my work. As I pulled out of mcdonald's the car started to slow down and would not accelerate. I thought it was my gas so I pulled into exxon down the street to fill up on gas. I put $15 of gas into the tank. When I started to car up it immediately started shaking vigorously and a strong smell of gas and cloudy fumes came from my exhaust pipe. I had to go back to work so I drove the two miles while to car strongly shook and the exhaust pipe was producing a cloud of smoke that smelled heavily of gas. I got to work and called my husband. I turned off the car and checked my oil. I attempted to turn on my car again and was not able to get my car to start again that day. At 7pm I attempted to turn my car on again and it just made a loud screechy sound and would not turn on. 2. Because car would not start we called harry's towing to be towed to a auto shop nearest to our home. Our car never before has had any problems at all. 3. We asked the mechanic to look at the car and identify the problem. When he called us back he said the fuel injector was the problem and he at that time had replaced it already and advised us to take the car to Ford due to the fact the he said the motor was dead as well. We then had the car towed to Ford in franklin kentucky. They identified the problem as the fuel injector and that the motor failure was due to fuel injector problems. The headquarters of Ford said we are now not covered under the extended warranty due to the fact that we took the car to someone besides Ford.
