Is this fair price?, I seriously doubt it! Options

Yesterday afternoon when I was leaving parking lot my car suddenly stuttered and died. I tried to start her again but no dice. She'll crank but would not start.
My assumption was immediately fuel pump, because it used to whine a little but now when I turn the key to ON position it won't even make a sound.

Long story short: I broke down about half mile down the street from Tansky Toyota in Dublin OH. I used one of my three AAA tows and had her towed to their shop. Today I got a phone call from the manger telling me that the car is throwing two codes: fuel pump and knock sensor.
I am not mechanically 100% so my question is: what are the chances of pump going out at the same time as the knock sensor?

Also, the dealer quoted me over $1200 (without the tax) to fix the car. That seems to me WAY too steep.
What are your thoughts guys?

ok man im a mechanic myself that price is way too hi when you go to the dealer they usually get parts from aftermarket shops such as places like my work (advanced auto parts, autozone ect..) then do whats called a mark up. So a part for example that ran 80 dollars at my place, pep boys buys and then says it ran 350 in parts I saw this happen on numerous occasions at dealers an other places (im in charge of the commercial accounts) as well if its spitting out a code for a knock senser thats not the problem the problem is probrably the to do with the fuel system as the knock sensor only messures vibration in the engine. try the fuel relay first and the fuel pump fuse see if either is the cause small majority of the time this is usually the problem if not you can get a fuel pressure guage to test the fuel pressure for like $25 if you can get the codes it shot out i can definetly give you the a list of three to four probable causes on this let me know ill try to help as much as i can ooohh an change the fuel filter as well
