2003 f250 6.0

hard to start and runs rough unless i unhook the #7 injector.
then it will start right up and idle.

so i swapped #3 and # 7 injectors to see if i had a faulty injector.
nope still have to unplug #7 to get to run.

while it is running and u try to connect #7 back up it will stutter and die.

so i had it running and unhooked #5 and put #7 connector on 5 and it died.

so i took the injector harness off and ohmed it out and no shorts.

FMP is 48

any ideas????

FICM power board (source for 48V) isn't the only area of potential failure of a FICM.

Can you try (borrow) a known good FICM?
