What does it look like when the injectors are squirting? I'm not seeing any oil circulating around the Injectors or anything I also went and checked wiring and a few other things I love the obs trucks but man im missing the simplicity of my old 12 valve cummins. Does anyone know anyone that has a snap on scanner around in Oregon that could scan this for me?

HPOP don't usually just go
Can pressure test HPOP but need a 0-4000 PSI gauge for it or use a scanner if ICP is ok

These has a mechanical fuel pump unless upgraded to efuel

Why are the measurements in metric? The scanner can't tell fuel pressure, so don't go by what the scanner shows for it.

No i tested the fuel pressure with a gauge on the port on the fuel pressure regulator. I didn't even notice it was metric and any idea why it took so long while cranking to build pressure I'm also gonna put a gauge on the fuel line going into the head. I will rescan it tomorrow and get the results in standard not metic
