im new here this is my first post.. i recently got a 2000 blazer 4x4 4.3 auto. it threw a code the other day and i had it checked and it said it was the fuel pressure sensor. said to check the sensor and all hoses and fittings. my problem is where is it located? would it hurt anything to keep driving?

This thread should help you out. Be sure to read the diagnostic info for your code in the DIY section.

 

it doesnt seem to affect the driving at all.. i had a friend tell me to brake torque it and i told him it wouldnt.. so i tried and then the check engine light came on.. it threw the P0446.
