Does the engine start when it's cooled down? Does the high pressure oil reservoir fill with oil as the engine is cranked over? If it doesn't, your low pressure oil system is starving the high pressure oil system supply, which can either be caused by a worn low pressure oil pump or a torn oil pickup gasket. If oil fills up the high pressure oil reservoir normally, you'll need to focus on the high pressure oil system. Do you have access to the 7.3L block-off tools? If not, perhaps it would be a good idea to borrow them from your local nearest dealer as well as the coupler release tool to remove the high pressure oil supply hose to each bank. You can block off one bank at a time to see if the engine starts afterward and if it doesn't, you'll need to block off both banks, dead-heading the high pressure oil pump to check its output. I believe you should see ICP pressure climb rapidly to 1500psi with both banks blocked off.

I would buy the Adrenaline from www.dieselsite.com
I put mine in 2 weeks ago as an upgrade and love it! I dont think it is that much more than a stocker re-man

its WAY more than a stocker re man! holy cow, read up on this thing. It flows oil like crazy. Diesel Power mag did a write up on how they put it in an OBS, with stage 1s, and it gave 35 HP, and 95 lb ft to the ground over the stock pump.

I know it flows more, I can't believe it... it's the best money I've sepent so far (besides custom tuning)

I was talking price wise in my previous post, the adrenaline is 589, and a stocker re-man is like 400-450, so it's deff worth it
