crank then stall
 

I have and 05 250 with 220,000 been having a throttle type problem. near the end of the day it would start dragging when I would hit the gas. This morning drove it to the shop and it would not start. Fuel pump was replaced 6 months ago. So we put gauge on it and no pressure. We replaced the pump and it crunk but drove it down the road and starts stalling and shaking and quits. it has pressure. Just cranks idles then slowly starts stalling and dies:scare2:

changed out ficm still nothing when we get it to start it runs like crap. skipping and then dieing.. It had thrown a crank sensor code, glow plug code and #1 injector code but we cleared them and they didn't come back but still not running

Check fuel pressure again and high pressure oil HPOP pressure with scanner
