I have a 2004 Jeep Grand Cherokee Laredo with 80,000 miles on it. In the last two years since we've bought it, we've replaced the fuel pump 6 times -- all by the same mechanic! Four out of those six fuel pumps were replaced in the last 6 months. EVERY TIME the Jeep died, we brought it back to him, he replaced the fuel pump, and it ran great again (sometimes for only 45 minutes, sometimes for 2-3 months). Well, the Jeep won't start again and ANOTHER mechanic is telling me it's the fuel pump AND the fuel tank that needs replaced now. My original mechanic says it's the fuel pump again. Really?? I've had it up to HERE with this merry-go-round, so I'm looking for help. I've paid over $450 in fuel pump replacements and labor, not to mention the additional cost of rental cars, towing, "wiring" parts he's replaced, and other business I've given to him such as tune-ups, oil changes, new shocks, and so on. Why is this happening? What else could the problem be? What should I have the original mechanic look into next? At the moment, the Jeep will start, but then it behaves as if it's not getting enough gas, running out of gas, or only intermitten gas. The best I can describe it is like this (I'm sorry, I know nothing about cars): "VRRRRooom, put, put, put, put VRRRROOOmmmm, put, put, vrrrrrrrooom, put, put, put.." and then it dies. PLEASE, PLEASE, PLEASE HELP ME!
