B1600 code: PATS and resolution
Yesterday My '06 Expy with 5.4l was in "no-starty" mode; crank - no start. I have after-market car-start installed; so while trouble-googling I called the place who installed it - made no headway except to rule OUT the PATS. See, despite the code: B1600 - Ign Key Signal Not Rcvd PATS; my truck wasn't behaving as if the PATS wasn't working. Using the key switching on the ignition my dash-top security light would stop blinking as normal.
Started checking fuses: Fuel pump relay fuse was blown. I replaced and attempted re-start. Pop! Blew again.
Google lead me to: 2006 Expedition FPDM / Fuel Pump issue FIXED - pics - Ford Truck Enthusiasts Forums
I unplugged the FPDM Fuel Pump Driver Module - plugged in a replacement from local auto parts store. Replaced the fuse again, and...
Truck started! Varoom!
I can only guess why the PATS code was showing - I'm assuming the anti-theft is linked to disabling the fuel pump. When the ECU did not get a signal from the pump it assumed it was the PATS not 'releasing' the pump's power.
I tried PBBlaster and a torch to extricate the original piece - nothing worked. I'm sure I'll have to cut off the bolt heads of the old one to remove it. Mean time the replacement is tucked in a cranny and hose-clamped in place.
My purpose with this thread: Adding to the database in case another person runs into similar problems and codes and whatnot.
From attached image; the module is shown circled; with the replacement hanging. That's the driver's side, rear tire in the pic - with my head where the spare would be.

Thanks fer the addition to the knowledge base - good fer you fer placing the error code in the title.
Dorman replacement? Oye.
Either get another one and keep it in the truck as a spare, or if ye can, return it & get the Motorcraft replacement ( and don't fergit to use them standoffs)
Dorman failure rates are unacceptable, IMHO.

Standoffs:

The Dorman equivalents are rubber grommets.
Try Tasca fer a good price on the MC FPDM.

Code b1600
I have a 2008 Ford F150 Harley Davidson Ed that had a code B1600 with the check engine light flashing. I've replaced the Transceiver and it still will not start. I've replaced the battey and it still won't start. It's been towed to the dealership but was told that it started when it arrived and it's probably a key issue. I'm now using the spare key and it still will not start. I removed the Remote Start System with deluxe vehicle security and keyless entry thinking it was the problem and it still will not start as in will not turn over. Any help on this issue will be greatly appreciated. Also I've read all the info that I could find on fourms and websites but it did not help.
