7.3 powerstroke no start hot
For all my diesel guys, I need some help! I got a 7.3 that won't start at 180°f oil temp. Customer installed new icp & ipr w/ pigtails, hpop and lpop. I installed new injectors and replaced the pick up tube gasket "not building lp oil when hot". it got slightly better but still won't start around 190°f oil temp. Any ideas?

Icp builds to 320psi and ipr goes to 65% duty cycle. So it's like it's got a high pressure oil leak but I can't find it anywhere.

Okay I'll get those fittings and check pressures at the heads. I've tested all the other parts and swapped known good parts on with no change. Thanks for all the help!
