Fuel Rail Pressure Sensor help
Hey guys. So I wanted to take my car out to make sure the fuel pressure was good and everything. mell0 helped me do my dash pod and boost gauge setup (thanks andy) So I tied the boost vac line in to the fuel rail pressure sensor. I got a code saying "Fuel Rail Pressure Circuit Malfunction"
I thought maybe I pinched off a line, so I re-routed that to a differant vacuum line. Thats all set.
But the on my dads scan tool, I can datalog (kind of) And my fuel pressure seem to jump around a lot. I went WOT in 2nd and hit like 65lb, then driving around it was going like 39, 38, 42, 40, 44, 39...a couple times it hit 36, and twice it hit 34...I dont know if thats too low? So is it possible that my Fuel rail pressure sensor is shitting the bed? Could I use the one off my Dad's 03 Mach 1 to see if thats what it is? Thanks for all the help guys - Shaun
