Review on FICM 6.0 Powerstroke Fuel Injection Control Module for Ford F250 F350 F450 F550 & Excursion - Replaces OEM Numbers 904-229, 1845117C6, 3C3Z12B599AARM, 4C3Z12B599AARM by Erick Roby

Installed this replacement FICM in 2004 6.0 to replace an old FICM that reads 31V but still works. TRUCK WILL NOT START. The OBD monitor showed 48 volts but the engine just revved and blew white smoke (this was NOT the case before, even with the bad original FICM). Plugged the old one back in, just in case, and it fired up like it used to (not great like it did in the 30's, but it started and ran at 31 volts). So waste of time. Maybe your time is wasted? I DO NOT WANT A REPLACEMENT FROM THIS COMPANY.
