      Please clarify something. If you take a line off the fuel filter and turn the key to crank, you are saying that there is NO fuel flow there? Yes / No clear answer please. This "carb" you refer to is not a carburetor, it is a Throttle Body and the system is known as TBI or throttle body injection, just sayin.

      Test AIR PUMP A fuse. The P0420 means the cat is junk about 90% of the time. About 10% of the time the rear O2 sensor is junk.

      Do you have a security light illuminated on the panel? If so you likely have a faulty ignition lock cylinder or a faulty ignition key. the key has a resistor embedded in it that the ignition lock cylinder and security module read the value of and this is like a password that enables fuel.

      The blower motor runs by receiving battery voltage and a ground. You just stated that there is battery voltage at the blower motor. Now check and confirm that there is a ground. It should run and if it does not then the motor is junk. Try smacking it with something while power is applied to it. It may begin to run.

      Book labor for this job is 12.5 hours, but I doubt anyone will pay any mind to that. Major job that distracts you from getting other work done. Cannot be done properly in 12.5 hours so labor gets upped to about 18 hours at around $100 / hour plus the list price on the parts. Most shops will not do a job like this cheap. But ya never know. Requires high skill level. Often you get what you pay for.

      Replace the fuel pump relay or at least remove it and that should stop the pump from running.

      Remove the START 1 relay from the underhood fuse box. If the problem is still there then yes the starter is stuck and needs to be replaced.

      Check the many on-line auto parts sources, such as; www.autopartswarehouse.com, wwwpartsgeek.com, www.autoanything.com and www.rockauto.com - to list only a few sources. For example, they (Rock Auto) list the fuel pressure sensor from around $19.40 for your vehicle (Standard Motor Products part #AS302) or equivalent.
      The fuel pressure sensor is easily replaced, refer to the 'How-To-Guides' feature on the AutoMD website, or the repair help website at www.autozone.com - as just two examples.

      No not the FTPS, replace the Canister Purge Solenoid / Valve. At a shop about $150 to $200

      Besides the sources advised by other fellow members, you can also consider visiting http://www.autopartsfair.com/ , as they have million of auto stuffs in their inventory. I too recently bought some engine parts for my Silverado from them and found them quite reasonably priced. If you know basics of DIY's then you can do this by visiting tutorials posted at online tutorials.
