No Start after HG's

just finished doing HG and injectors, now the truck won't start. its a 2005 EX have checked everything oil system is tight but it is not producing any pressure build-up, oil is in the rails as verified by removing the bleed plug on driver side and ICP on pass side. it has the updated standpipes and dummy plugs, at wits end and not sure where to check next

FICM 48 constant
IPR goes from ~45 to 77

IPR should be 14 at KOEO and 85 while cranking with low ICP pressure.

Is there a tuner on it? What is your fpw while cranking?

Josh, I can't find my reference for it but isn't 77 a common number for a failed IPR? (I meant ICP)

I think that ended up being a weird coincidence a couple of different times IIRC.

But I believe you're on the right track... The IPR is likely clogged or damaged.
