6.0 wont crank

My truck was running very rough then the check engine light came on. Had ford put it on the computer. they told me to replace the IPR , the ICP sensor, the egr valve . Also the branch tube adapter on the high pressure oil pump. I did all of this. The motor wouldn't crank. Took it back to ford and they diagnosed it and told me it needed a high pressure oil pump although before the upgrade it was building 590 PSI now it only builds 300. So i broke down and replaced the HP oil pump. Still wont crank. Please help this is my only vehicle .

I think you need to crank on them a while after this repair to fill the system with oil. I could be wrong but here is a bump.

the other thing could be the FICM and it's not fueling it up right to start it

I guess i will have to get a computer to check it again during cranking to see what the issue is. for some reason I think it is still not building the required oil pressure. are there any ways to check the FICM to see if it is working other than the computer?

not sure if there are any other ways to check on it, but if you have done the icp and the other sensors and whatnot the ficm seems to be the last item it could be this is a quote from one of the techs on here if it helps ....

"The Ford part number for a FICM is 4C3Z-12B599-AARM for ALL 6.0L engines from 2003 to current model years, whether it's for an E-Series or F-Series. When you purchase a new one however, it will need to be programmed to your vehicle using Ford's IDS scan tool. Another quick and easy way to confirm the FICM has failed is to connect a scan tool that you can read live data with. Access FICM_L, FICM_M and FICM_V readings at key-on/engine-off. FICM_L and FICM_V readings should be around 12 volts (battery voltage). FICM_M should read between 47.5 to 48.0 volts. These readings should remain the same at key-on/engine-off and key-on/engine running. If you see all three readings decrease (particularly FICM_M) as you attempt to start the engine, or if you increase engine RPM, that's the telltale sign that the FICM has failed with 100% certainty."
