How to test oil pressure

[cory_ocnnr]

Ok I a 2003 6.0. My problem start on my way home from work. The truck just died on me. Started it back up and got home. Pulling into the driveway the truck died again and wont start at all now. About a year and a half ago I replaced the hpop, hpop tube, icp, ipr, oil cooler screen and ect. I got a scan tool from a buddy of mine and hooked it up. I have no oil pressure. Any ideas needed. Thanks
