crank and no start with codes

Trying to help a friend with his 2001 7.3...crank and no start...

we threw an extra CPS I had for my truck in...still no start...pulled the ICP connector off to allow the truck to operate at the ICP default values...still no crank

had the codes read from a guy that had a test set and these are the codes..

P0470
P0470 Exhaust back pressure sensor circuit malfunction Biased sensor, open signal return




P0603
P0603 Internal control module KAM error Open PCM pin, disconnect B+, faulty PCM


P1280
P1280 ICP circuit out of range low Open/grounded circuit, biased sensor, PCM


I'm thinking PCM....

what are yalls opinions on this with the codes I provided???

we may have found it....found several of the connectors on the PCM loose, removed them, added some dielectric grease to the connectors, tightened everything down real good...and she fired right up....shocked the crap out of me!!!!!
