Had our 3 in the shop for 2 days. If you tried to start the car, it would take at least 2 attempts, to get it started. It would not fire on the first attempt. This lead me to believe it was a fuel pump or fuel pressure problem. Took it to the dealer on Tuesday (2/10/04) and they told me it was a bad fuel pump. The pressure in the line was dropping to 10psi after 2 minutes when the car was off. They had to order the pump, and they gave me an '04 Suburban with 7 miles on it. Not a bad loaner. Picked it back up last night (2/12/04). They said that had 2 more come in the same day with the same problem. Everything is back to normal now.
