.2 volts on ICP and 0 psi??

I have the no hot start problem, ordered the STC fitting update kit but haven't put it in yet. Just want to make sure that's the actual problem before I tear into it. It runs fine but takes 6-10 seconds to start cold. After it's warmed up, I have 0 psi and .2 volts on ICP. I'm reading that from my edge insight. If it was the STC fitting, would I be getting 0 psi or should there be at least some pressure? Thanks in advance to any help.

I think your ect is screwing up. If you actually had 0 psi your truck would not run.
This does not mean that you do not have some type of oil pressure loss. Actual testing with mechanical gauges is needed for verification.

Something isn't right....are those readings while it's running? ICP should be .24ish KOEO.

Ok, so back to my original question. Should I be reading 0psi with the key in ON position like i'm getting ready to start it? I understand that a high pressue oil system leak will cause decreased pressure but should it have some pressure or none?

with the engine off, there is no high pressure oil. The reading is normal. When cranking you need around 500 minimum.
