Volvo: 1993 940-B230F- NO START, fuel pressure regulator, regina system

Question
SCENARIO; My wife started her car, put it into D, got about 50 ft and lost throttle, and engine died as if it were out of gas.  Tank is 1/2 full, plenty of spark, but won't start.  Presently,  I have checked everything (sensors etc) from front to back with DVOM, swapped fuel filter, swapped fuel pump relay with my daughters '86 Volvo (worked great in  her car), checked fuses, pulled codes -122 on #2 port, pulled and checked distributor cap and rotor, checked vacuum lines, fuel pressure regulator, replaced throttle sensor which tested zero, and traced fuel lines for any kinks etc.  So far so good, but still a no start.  Engine almost acts like it's "vapor locked" in that I have fuel up to filter, but nothing between filter and engine. (Yep, arrow on filter is pointing the right direction)  This is a Regina system, and I'm admitting it has kicked my butt for three days, and I'm throwing in the towel. I'm thinking it's the in tank fuel pump which I understand I have to drop tank to access.                                            I'll hold off dropping the tank (and/or buying my wife a new Hyundai) until I hear whether or not you have an ace up your sleeve to help me out of this predicament.  Your help is greatly appreciated.  Thanks, Chuck  

Answer
Chuck,
All your tests lead to the fuel pump. No gas at the fuel rail, correct? Either pump is burnt out or no power going to it. Test at the connector to the pump (red or pink wire) and see it you get power to that wire. You do not drop the tank. Inside the trunk below the hat shelf pull back the carpet and you will see a small plate. Under that plate is the sender and the pump is on the end of the sender.
Code #
* 1-2-2 Air temp. sensor signal absent or faulty


 


Conditions for fault code:
If the signal from the temperature sensor is too high or too low, the control unit compensates with a value corresponding to approx. 20°C (68°F) (limp-home) so that the car can still be driven.
The fault code is set and the Check Engine lamp lights up.

Causes of faults:
Break or short circuit to ground in the wiring, connections or sensor. Connection resistance in connectors. Poor chassis connection of signal ground.

Fault symptom:
Engine dies at idle.
