I am trouble shooting a fuel injection system and need to know when adjusting the fuel pressure @28psi, should I be getting that reading with the starter turning or just with the ignition turned on so the fuel pump turns on.
Thanks, Michael |

Let me start by saying, Yes, I know I am an idiot. When I test with the fuel pump on it will only read max 20 psi on the fuel pressure gauge. I can not adjust the fuel pressure regulator to read any higher. If I test with the starter turning the pressure will jump much higher.
