i have a 2004 fx4 with 5.4 triton. i've replaced the fuel pump, filter, and have put 2 new fuel pump drive modules on (one aftermarket and one oem ) i can hear the fuel pump running but the engine will not turn over. the anti-theft light blinks eratically and the info cluster reads "check gauges". does something need to be reset or recoded for the computer to accept these new FPDM'S?
