So after I finished installing engine etc. On first start I had codes p0087 and p0090.
From what I've seen (87) in tank pump (90) high pressure pump.
I'm curious how they would both go bad from sitting. I replaced the in tank pump thinking it was the issue to both codes and now no current (87) but still have p0090. Is there a way for me to specifically test the high pressure pump itself? I checked fuses multiple times and no issues there. But maybe I'm skipping something.
