2006 4.0 automatic Rubicon. Non start issue. Starter spins motor but motor will not run. Doing the key dance code PO627 is indicated. The description for this is 'Fuel Pump 'A' Control Circuit / Open. I have checked all the fuses and replaced the fuel pump relay. I am not getting any voltage in the wiring going into the pump at the tank. One day prior to the non start i installed a new battery. Everything started just fine. The next morning it started fine but later that day it would not start. If anyone has any ideas i would greatly appreciate it. Thanks!
