I need help diagnosing my truck. it started with the normal FICM issues. I did the repair but the truck wouldn't start afterwards. I checked the voltages from the FICM and was getting 48v. The truck would then crank for a about 10-15 sec and would start and run rough for 2-3sec and then die. well trying to get it to start I ran the batteries dead. while cranking everything shut off but the starter continued to crank until the batteries died. I took both batteries out and charged them up and tried putting them in but when connected the starter would start running again. I pulled the starter and checked the solenoid and relays and it is all fine. reinstalled everything and no more problem. Now all the lights are on keyless entry works but, the odometer reads "000000" and turning the key does nothing no noises, no WTS, no radio, no gauges, just nothing. It is driving me nuts. any help would be very helpful. oh this is a '05 f350

well I ended up having it towed to the dealer. it turned out to be that the FICM, that I had repaired twice, finally bit the dust and was shorting everything out.
