2001 Expy, cranks, no start, injectors not pulsing
 

Ok, so here's the sit-rep: 2001 5.4 Expedition. Came out one morning, hit the key, engine just cranks. Fuel pump has a very abbreviated run, and pressure at the rail is a drool. Ran a jumper wire to the fuel pump, and it runs fine, with full pressure at check valve.
The problem is, the truck still won't start. It WILL run on ether. So, this kicks my problem to the injectors. All fuses for PCM/ECU etc are good. Fuel Pressure regulator is new.

What is wrong with this thing? 117,000 miles.

What does the THEFT light do when the ignition switch is turned from OFF to RUN?

Blinks like crazy, which according to the manual, means the anti theft system needs to be serviced? Whatever that means. How do you service an alarm?

It means that PATS prove-out has failed and the computer has disabled the engine.

Don't know if this will help but if you have a System 3/4 Alarm you can reset it, read this post:

Edit: Just disconnecting the battery for 10-30 minutes may re-set the PATS system - worth a try.

No, we figured it out. The owner had left us his dummy key. It works all the locks and such, but lacks the chip. He's in Cali at a funeral, but we were supposed to move it to a tranny shop to get fixed. Kinda hard to do that without the chipped key....
Thanks to all who offered help.
