So I started monitoring my FRP so I could see if I'm gelling up. Anyway truck runs great no problems but I e noticed it takes nothing to get 25k pressure is this normal. FRP idles at 4.8 and cruising down the highway it's around 10 or 11

That's fine. If you were cruising at 15k+ plus all the time or it for some reason was seeing 26k+ FRP maybe, but yours is normal. Now if low FRP happens, diagnose immediately....ask me how I know lol

A six four doesn't have ipr. You need to monitor rail pressure which may be called icp. It should be around 4.4ksi

What Sootie said. Although since it won't start i doubt any RP readings will occur at all
