For the last 3-4 months my 2005 GC WK 4.7L(132K miles) has had some issued at start up. At first I thought it was the transmission slipping, I did a tranny filter and fluid change at 100K). The vehicle starts with no issues but when I put it in drive or reverse there is a delay before the vehicle will actually move. After the initial hesitation there are no issues until the last week. It seems that when I park in my driveway, which has a slight incline, I have the initial hesitation but then when I get to the stop sign at the end of my block the vehicle stalls. Start it back up and drive with no issues. When I park in the street I have yet to have the vehicle stall after initial start up. I've never had a fuel pump issue with any of my other vehicles and don't have any experience with fp issues. Anyone with any fp experience that could confirm my concerns???
