If the radio it self goes out, the whole screen goes blank, and it does not loose its memory, then it will most likely be internal of the radio. If the sound just cuts out and the radio stays on then it might be the amplifier. We always suggest having it diagnosed by someone with the equipment and knowledge because in the long run it's less expensive then guessing, especially on electronic parts.

1st step is to see what the coolant temp. sensor is reading when it is cold. Not the gauge on the dash but the sensor for the computer. If it is reading too high the vehicle will not get enough injector on time for a cold start. Basically the computer thinks the vehicle is already warmed up. If that's ok next is to test fuel pressure. If it's low again the vehicle will not get enough fuel flow for a cold start.

If the pressures are good when it goes warm and the outlet pipe from the evaporator is still cold at that time it may be a problem with the ATC system in the vehicle.

In my opinion... we go with factory convertors when ever possible but I have had luck with the Walker brand. I agree with Pushrod, you may want to test/change the O2 sensors first. We alway but in new O2's with new convertors so sometimes we will change them first with the understanding the customer may need a convertor also. We do all the O2's upstream and down stream.
Question Answered: 1992 Cadillac El Dorado does not start due to anti theft system. Any suggestions

If I remember correctly the '92 Cadillacs have the resistor pellet in the key. Because you already tried a different key the problem could be a broken wire from the ignition tumbler to the connector under the dash. Have someone test the resistance of the tumbler and replace if needed.
