Fixed it today! It was a dirty MAF sensor. I found it by simply unplugging the sensor,, and trying to start it again! It started and ran as long as the MAF sensor was unplugged, but when I plugged it back in it would die in just a couple of seconds. I learned that many sensors can go out of range and cause the ECM to shut off the fuel pump to prevent damage to the engine. The sensor is $200 at most part stores but they were all out of stock and would have to be ordered. I was told by one mechanic to get a can of MAF cleaner and a baby tooth brush, remove the sensor, and spray cleaner on the 2 small resistors and brush them gently until they looked shiny, and new, then reinstall the sensor. I followed his directions, and it is working flawlessly again! Thank's and I hope this experience helps others with similar issues.
