One of the common callouts was a Fuel Pump Driver Module.

It's going back to the seller.I searched YouTube for longer than I probably should trying to find the cause/fix. The locksmith could not pair the keys with the new PCM. Unfortunately, there is no communication with that new PCM from the OBDII port. Super dangerous.I ordered a new PCM and the company supposedly programmed the VIN and updated the software on it. After almost two weeks on their lot, I was told that it's probably a problem with a wiring harness, but they could not identify where the problem was.The problem now got worse, and the car started stalling while driving. The problem continued.I send the car to a local Ford dealer for diagnostics. We replaced the instument cluster, transponder, and ignition switch. Then, the problem would exhibit with a higher frequency.My local mechanic diagnosed it as a faulty instrument cluster. PATS light was rapidly blinking and the car would start and run without an issue after a few tries. They mainly showed up when I tried to start the car in the morning. 2007 Ford Expedition EL Limited- No Crank No StartBackground: my Expedition began having intermittent no crank issues around three months ago.
