1992 Toyota Camry Repair Question
92 toyota Camry stalling and wont restart
check your fuel pressure it may be a tad bit low and is taking a while to affect your car. it should be 38-44 psi if it's lower then it wil need replacing. i am sending the chart. pay attention to footnote #1. it tells you how to do this correctly.

Check and test the airflow meter this the one that grounds the COR to power the fuel pump-BTDT or do it my way in the DLC jumper Batt to Fp this will power it when you turn key on and stay running let us know-
Tested the fuel pump and with ignition on and jumper between fp and b+ the fuel pressure was 44psi. started engine and left vacuum line attached and pressure stayed at 36 psi right up to the engine stalling 20 minutes later. Tried to restart but all she would do is turn over. Pressure stayed at 45 psi during cranking. Tested water temp sensor and read 204 ohms but not sure if my meter has some variation. I will test the air flow meter.Engine seams to die 3 seconds before the fuel pump shuts down.If it was the air flow meter wouldn't it break my pump circuit to shut it down? Only thing I can see now that may be happening is that I'm loosing my fuel injectors or the computer is shutting the injectors down. Unfortunately I do not have anything that I can test the injectors circuit as far as I know. Manual says not to use a meter but to use a light that I do not have.
Tested the air flow vacuum meter and with ignition on 5 volts incoming power. checked the sensor and with engine not running had 3.55 volts. put vacuum on sensor and voltage fluctuated down as vacuum came up.
Remove jumper from the DLC and block open the AF meter flap and retest -see what happens
Check if the exhaust system is restricted due to a clogged catalytic converter-
This car has a vacuum sensor. and not a MAS with flap. You may be onto something with the converter. Past experience with converters is that they restrict flow but will run until you put power to it. The converter was replaced 35,000 miles ago.I'm thinking that I may have to check and see if my injectors are shutting down. Do you know a good way to test them?
