My 2005 Durango 5.7 had always started instantly as I turned the ignition. When it went over 40,000 miles, it would take at least two turns of the ignition key before starting. Also, (sometimes, but not always) there is a slight engine hesitation at idle that lasts for only a couple of seconds. Engine runs great at all other rpms. Took it to Dodge. They did a diagnostic and said my fuel pump wasn't making enough pressure. Hence, I needed to install a new one. I find it hard to believe the fuel pump went bad after only 40,000 miles. My Durango runs great while accelerating and at WOT. If my pump wasn't producing enough pressure, wouldn't the engine cut out during high demand acceleration? Any ideas anyone?
