Can the ecu or a bad sensor cause the car to start but run for only about a sec?

What is your question?

92 corolla starts easily but only runs for about 1 second. I think the ecu tells the fuel injectors to stop squirting fuel once the motor starts. New fuel filter. Fuel pump and injectors work and good pressure in the fuel rail. Motor runs good with a home made vapor carb with or without injectors unplugged in. Injectors squirt well when the motor is turning over but not running. How can I get the injectors to continue to squirt once the motor starts? Is there anything in the distributor that can stop the injectors? Should I replace the ecu? Could it be a bad sensor?

How long has your 1992 Toyota Corolla had this problem?
