2003 Cadillac DeVille Pump Issue

Been having a number of issues with my car, any help or advice would be sincerely appreciated!

  1. Leaky gasket and oil in spark plugs. Replaced both. Also changed oil and replaced oil filter.

  2. Massive loss of power, unable to reach even remotely high RPMs. Turns out the catalytic converter is plugged up and there's also an issue with the sensors detecting the drive train, and I need to clean the converter to get the RPMs up high enough for a reset. Got cleaner, opened fuel access hatch and drained fuel then filled it to 3.5 gallons as directed and added the cleaner.

Since doing this I haven't been able to get it to start up. It turns over but won't run. And yes, I have turned the key to the "on" position and let the pump run and repressurize the lines plenty of times.

My Dad passed recently and it was his car. I'm trying hard to fix it up but I'm stumped.
