yeah, I agree. You need to figure out why it won't start. If you have been running with your CEL on and suddenly, it won't start, it could be a number of things. Just because someone replaced the sensor once and it worked, doesn't mean yours will be fixed. You are going to bea little upset if you change it (bi@#*&%tch to get to) and you still have to buy a $200 fuel pump.

Start with the basics and give up some more info, or you are just throwing money around, in which case, you should just take it to the dealer.

Was your CEL on before it died? >> rent a scanner, turn the key on and get back on here with all of the codes.

Do you have spark when cranking? >>use the old screwdriver method...

Do you have fuel pressure? >>Test at the fuel rail.... looks like a tire valve..
