I recently changed the battery. Once changed, truck cranked properly. However, it will not shut off after key is removed. I am having to pull the ECM fuse to kill truck.
I have check fuses and relays and so far everything has checked out. I have understood, from online information, that it could be the ignition switch, fuel pump control module or a faulty ECM.
I have pulled codes from truck and they are the following: P2534 U3007 U3006 C05A4 P16BC P16A7 P0700 P1682
No problem or codes prior to changing battery
