Question Answered: My car's FM (haven't tried AM) stereo keeps turning off. How do I fix it?

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.
Question Answered: why does ac warm up under acceleration?

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.

Have a shop smoke test the intake system for vacuum leaks
Question Answered: When I start my Jeep a chirping sound comes from the valve cover, what is it?

I agree with the two above but because the battery is drained when starting cold have it tested also, it may be starting to get weak.

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.

First is to check the key fobs. The metal tab that holds the battery in will come loose a lot on these GM fobs. If it is get the fob repaired or replaced first.

If the intake manifold has not already been updated to the new one do yourself a favor and replace it with the job. You'll be better off in the long run.
Question Answered: what would cause the fuel pump to fail only a few days after replacing it?

Check for dirt in the tank. If it looks clean I would go to a different brand pump. You should also check the electrical connector at the pump, make sure it clean, tight, and not burnt.
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.
