No start condition...
Hello everyone - its been a while since I've checked in but here I am.
Tuesday evening, My '04 Durango (5.7L AWD, 140K miles, Sentry Key equipped) stopped cold on me in the driveway after a partial run down the driveway. It appears that the fuel pump has been shut down by something. I initially thought the pump had failed since there was zero pressure in the fuel rails. I replaced the pump today and it still appears that the pump is actually shut off. I'm not too upset about changing a pump that probably didn't need it - one less thing to go wrong later.
Where should I look next? The computer is not storing any DTCs that I can pull. Everything looks perfectly normal as far as I can tell. I've been reading that a faulty crankshaft or camshaft position sensor can cause the PCM to shut off the pump, but I'm pretty sure that it would kick off a DTC.
I am concerned about the possibility that the chip in the key may have died and now my Durango thinks its been stolen. I've left the battery cables off until morning hoping that a reset will set things right, but I'm losing hope.
No, I haven't tried the other key because the dealership I bought it from managed to lose it.
I'm open for suggestions...

Apologies for not replying sooner...
I finally gave up and drug it to the dealership, who also struggled to find the problem. They did find it however. Apparently I had a poor connection between the wiring harness and the Integrated Power Module (fuse box unit under the hood). They unplugged it to trace the wiring and cleaned the connector before reinstalling it and it fired right up.
I suggest you remove the module (easier to unplug it that way), clean the connection (they didn't say with what), and reinstall it. That's what worked on mine.
Good Luck!
