    You wasted 27 seconds. If the PCM does not see a crank signal after 3 second it shuts down the fuel pump. 3 seconds should be enough to pressurize the fuel system.

    I've got crank, no ignition. What could it be now? I checked the valve on the fuel rail, by depressing the needle and there seems to be no fuel pressure.
    Either you are not getting current to the fuel pump as Manic said or your fuel pump has bought the farm.

    Cool Re: 2001 DTS on Life Support

    Just ordered a new fuel pump and fuel filter from Rock Auto, I will not be defeated I will WIN, and I will post results when my parts arrive!

    After doing more research, I am also beginning to suspect clogged catalytic converter, thoughts>>?

    My thought: stop wasting time and money and pay a pro to diagnose it. You're currently ripping yourself off big-time.
