I have posted this in 2 other sections because it falls under other category. I have asked numerous friends who work on cars and camaros specifically. I checked all my sensors, changed the ECM, etc. It needs ether to start and than the injectors will start to fire themselves. When it warms up it will just shut off. It seems like it shuts off when it enters closed loop mode. I do not know what the problem is and I don't have any ideas. I need some help here because it is driving me nuts. Summer is almost over and I have only been able to drive this car once this year. It's like my baby is sick without any diagnosis. The computer I put in could also be bad. I don't know how to fully test it. I have searched the forums for hours looking for an answer.

 

If it runs on it's own for minutes, connect a fuel pressure gauge (available free at Auto Zone) and a timing light. Take the 50/50 and see if the fuel pressure goes away or if the ignition goes dead when it dies.
