Hi, my name is ***** ***** motor do you have in this?
ok, withb these codes , you most likely have a bad fuel pressure sensor, and it will cause a hard start or no start, if the pressure sensor is showing too high, it will shut of the fuel pump, have you had this on a scanner and seen what the fuel pressure sensor reading is?
this is most likely a bad fuel pressure sensor, and is common with these codes, we do alot of them for this exact problem, but until ypu read the sensor signal in the computer, its impossible to verify,Tim
it could read anywhere from 44 to 65 psi, if it does, then you most likely have a bad fuel flow control module, if it reads higher than 65 psi, replace the sensor, but its going to be one of these 2 components, the sensor is the most common,Tim
