I have a 04 f250 6.0, replaced hpop, and IPR. Still getting no oil pressure, no reading on dash, nor getting oil into the oil filter reservoir. I'm aware it could be low oil pressure pump, I took my relief valve out and it's scored up a bit. I'm lost on this no start. Please help

 

If you are not getting oil to the filter and the relief valve is free then it is your low pressure oil pump, you will have to remove the harmonic balancer to get to it

 

I removed the relief valve and cranked for 5-8 seconds and no oil came out the bore for the relief valve. Is that pretty much a guarantee its the low pressure pump? Is it worth replacing the relief valve if its scored up?

 

pretty much, and yes it wouldn't be a bad idea to replace it if it is scored up

 

I'll be ordering oem gears, I'll order the cover too. Do I need anything else?
