Replaced the engine fuse box in my 2011 Fiesta

[HMadd]

Good afternoon, all.
I need some help. I just replaced the fuse box in the engine compartment of my 2011 Fiesta, because of excessive corrosion. Before I cut any wiring, I disconnected the battery, removed all necessary components to access the fuse box wiring, then unplugged the ecm/pcm. I then cut out the old corroded fuse box and wired in the replacement, going wire by wire. After getting all the wiring done, I assembled the car enough to test. Please keep in mind this car started and ran before I started. When I tried to start the car, with on engine off the anti-theft blinks quickly, the power steering system malfunction and hill start disabled message are on, the engine will not crank, and I cannot connect to the ecm with my scan tool. Is this all an issue with immobilizer not recognizing the key or is there something else that I did when I wired in the new fuse box? Thank you in advance for any help

Hmmm. When you disconnected the fuse block, it does seem to work, but the key components missing are the very ones that come off the main battery post to the EPAS and the MAIN - with this is a split to the ABS system belonging to the engine compartment fuse block (At least in mine). But I also have a Passenger Fuse Block too.

So when you redid all those fuses, did you check your main 40A / 60A fuses that branch off to ABS and such?

Being you came across corroded wiring - the issues are the fuses may be affected by corrosion and broke too.
