not sure if there are any other ways to check on it, but if you have done the icp and the other sensors and whatnot the ficm seems to be the last item it could be this is a quote from one of the techs on here if it helps ....
"The Ford part number for a FICM is 4C3Z-12B599-AARM for ALL 6.0L engines from 2003 to current model years, whether it's for an E-Series or F-Series. When you purchase a new one however, it will need to be programmed to your vehicle using Ford's IDS scan tool. Another quick and easy way to confirm the FICM has failed is to connect a scan tool that you can read live data with. Access FICM_L, FICM_M and FICM_V readings at key-on/engine-off. FICM_L and FICM_V readings should be around 12 volts (battery voltage). FICM_M should read between 47.5 to 48.0 volts. These readings should remain the same at key-on/engine-off and key-on/engine running. If you see all three readings decrease (particularly FICM_M) as you attempt to start the engine, or if you increase engine RPM, that's the telltale sign that the FICM has failed with 100% certainty."
