Question about 2000 Cadillac Catera
Four things are needed in order for a car to run, fuel, air, and fire and at the correct time. First of all I did not hear anything about checking the ignition module. You can have this checked for free at most auto parts for free. This will keep you from getting spark and also can be a reason for not getting fuel. If this checks out I would then check to see that I am getting fuel. This car should have a schrader valve (looks like a tire valve) along the fuel rail, after trying to start the car, press down on the valve and see if it sprays fuel. If only a dribble you need to find out why. Is the fuel pump running? you should be able to hear it run with the key on. If not I would be looking as to why not. If not running, I like to take a rubber mallet and give the tank a good wack, this will sometimes get the pump going- but only for a short time. If the pump is running and you still don't have fuel preasure at the rail, change the fuel filter. If you do have fuel preasure at the rail, but not getting fuel at the injector, you may need to change the injector(provided that you have checked the ignition module first) Last but not least, does the car sound like it is turning over faster than normall when cranking? If so you may have broken your timing belt. I think Iv'e covered all the bases- good luck

Start with the EGR valve. It could be improperly functioning or faulty.
depending on the make and model of the vehicle, it will be in different areas, although your local auto part store will be able to tell you where it is. It will be somewhere along the air intake.
I would also check or change the mass air flow sensor.
This problem is common and a very easy fix even for a novice.

Check your fuel line and since you have replaced your spark plugs, you
may now check your alternator and see if enough current is flowing.
check the intake system, efi / carb, make sure air and gas is balance
these are just common points that will help you isolate the issue
