Hi Y'all,
Short-time lurker, first-time poster. I'm a long-term gearhead (35+ years of wrenching on American muscle, Euro vehicles from the '70s-90s, many late-model domestic cars & trucks, and various Asian makes, carbed, fuel injected, diesel, etc.) with good diagnostic skills, but I'm out of ideas on the next step in trying to get a friend's '02 (XLT, 3.0 V-6, automatic, 2WD) fixed. Since it's her sole vehicle and also her work truck, getting it going is a priority. As it stands, it will crank, but not start. If given starting fluid, it will start and run for a few moments, but that's it.
Here are the rough steps we've gone through (with who did the work in [brackets]):
After doing a good bit of research on teh interwebs, I'm suspecting the PATS because of: 1) the inability to engage the starter via the key, and 2) the lack of fuel. As I said in the list above, the ignition switch/tumbler/keys were replaced and an original coded key is on the keyring. How critical is key proximity to the PATS sensor ring around the lock assembly? Does the coded key now need to be taped/glued/whatnot inside the sensor ring (as seems to be done with many "bypass" threads)?
Am I on the right track in suspecting PATS, or is there something else I'm missing?
Thanks in advance for the assistance on this!

Here are the rough steps we've gone through (with who did the work in [brackets]):
- Truck was starting/running intermittently, ignition switch seemed iffy, was replaced. This included a new tumbler and two new non-PATS keys (an original coded PATS key is on the keyring). No crank after this. [owner]
- New starter installed. Still no crank via the key, but will crank (but not start) if starter solenoid is jumped to positive post on battery. [mechanic]
- I come onto the scene. Spark present. Power present to fuel pump relay and PCM relay, relays click, fuel pump whines. No fuel scent at tailpipe after multiple start attempts (no fuel pressure tester on hand at this point). MAF power & grounds good, but can't test signal because the engine won't run. [me]
- Owner does research and mentions camshaft position sensor/synchronizer as possible culprit. My research concurs. Age of parts is unknown, but vehicle has 175K on the odometer. Sensor/synchronizer replaced (using the guide on here -- thanks!). Old one was squeaky and had 1/16" lateral play at top of shaft. Still no start (still cranking via jumping the solenoid). [me]
- After going through five fuel injection test kits at three different AutoZone locations, finally find one that isn't missing the Ford Schrader valve adapter. Fuel pressure test shows 62 psi (engine not running, of course). [me]
