my 92 caprice will start and run for 2 sec then dies. wont idle on its own.

What is your question?

it will start, run for about 2 sec, then dies. if i disconnect the temperature control sensor it will start and idle perfectly for about twenty seconds then dies. Whats the problem, i just replaced the temp- control sensor, the fuel filter, and the o2 sensor is only 6 months old.
