It starts perfect cold, but once it warms up. it fails stating unless you give it some gas. The fuel pressure regulator is on the fuel pump on this car. If you suspect the fuel pressure regulator, how do you test it on the fuel pump?

  1. I do not suspect the fuel pressure regulator. I suspect the IAC – Idle Air Control.
