a few days ago upon starting my 2000 CLK320 Cabriolet, it did not start or idle without me pushing down the gas peddle. I listened at the fuel cap and could not hear the pump with the key on. Checked the fuses and they were OK. I need to check the relay before I start changing out the fuel pump, I replaced that 1 year ago. Is the relay in the PCM box? It is the only relay in there.

Also, after my ignition switch shorted out, I had a new one programmed to my car and it works fine, however, the front window switches do not work now. If I use the rear window switches the front and back window on each side go down together???

Thanks in advance for any help.
