OK Guys, My fuel head is back in the car and appears to be leak free. The injector settings are at about 30% variance max-min. Whether my piston works yet I don't know - the settings are very different now.
I am trying to set everything back to factory spec as a baseline. My system pressure pegged my gauge at 110++. I'm guessing 120-130 psi. My WUR cold pressure is 50 psi!! The manual says 20. So, I pull my WUR apart and remove one of the 2 springs. I then google the part No and find it is off a 3.6 Turbo. Maybe 50 psi is right for it, but with one spring removed I get 20 psi. Does anyone have access to the 1993 3.6 T WUR specs?
Not sure which way to go with this.
Have reduced my system pressure to 85, have 4 spare shims now - only using one.
