Long crank times

I bought a 2004 f250 with oil in the water couple months ago, I took it down to the block and put head gaskets, head studs for arp, new oil cooler, oil cooler top cover ( because of bad seal believed to be anti-drain valve', egr cooler, turbo, plastic tube from intercooler to engine, ipr, icp sensor, and all necessary gaskets. It started up with minimal crank time for first start. I only ran it for couple minutes because i realized my heater core was leaking. I installed new heater core couple days later and let it run 30 minutes and checked codes. I was showing code for all 8 injectors so I called ford tech that i trust for thoughts and he thought the same as me so I sent ficm off repair and upgrade ( it was running fine I just didnt like having the codes edpresent). I have had turbo lag believed to be relearned but had not spent much time on the road just ran at friends shop. I received ficm back 4 days later and codes are gone now. I ran it for couple days at 15 minutes a piece for peace of mind. I decided last saturday to drive it all day. It did good till end of the day when i was dropping off trailer at friends i repaired the floor. the oil psessure dropped but was running fine. I did notice it sounded like it developed a whining noise that increased with the rpm. Since that day it has also had 30 second or more( no the case before hand). I pressurized the high pressure oil rail for thirty seconds and closed the ipr and did not hear and gurgling noises threw the oil filter housing. can somebody give me little insight please. I have bein told that i should test the hpop for longer time just dont close the ipr but around 80%. comments?

150 miles total so far. The saturday that it acted up i left it running most of the day with few breaks. I have put a programmer on it as well and nothing seems to effect it for better or worse. I am contempating buying a new hpop, new down tubes, and the stc fitting just for peace of mind.

FICM voltage ?
ICP values at crank ??
IPR values at crank ???

Do you hear fuel pump come up to pressure and stop ?
Have you installed the blue spring upgrade for fuel pressure regulator?

If I had to just take a stab in the dark my gut feeling is your IPR. Very common to have them get plugged with debris after oil cooler etc work. Shop rags are most often the culprit from wiping down engine block etc. Pull out the IPR and take a look at the screen. ( lint )
Would also explain the noise at rpm.

Good Luck with it.

ficm is 54.5 icp reads around 180 till it finally starts not sure about the ipr i did do the blue spring upgrade fuel pump is running with plenty of volume i try not to use rags but it could very well be, i usually use tampons for that reason( :-) ) I intend on taking it down to the pump this weekend if i need to go that far, i did put n new ipr but i know that does not guarantee success every time lol. Thanks

180 is a huge problem. The computer will not turn on ficm until hpo pressure reaches 500.
It sounds to me like you have a hpo leak. A healthy engine will crank above 500 very quickly usually in the 800 range until it starts then IPR scales back to the 580 range.

There are different year designs on 04 iirc you have a leak on the top most likely. Orings or standpipes dummy plugs design dependent.

Rule out IPR before you tear into it.

if you have a way of pressurizing the high pressure system and closing off the ipr during the test , be a good place to start before just buying parts

I do have the adaptor to put in the icp location. I pressurized it with driver valve cover off (because it easier) and could hear air blowing not sure location. Pulled out the oil tubes and they looked fine but went ahead and changed them just to please my peace of mind. Went lil bit deeper and pulled out hpop and found that the little ball that is suppose to be in the side of the pump was completely gone.I was surpised because the truck was still running when I pulled it in the shop. That must have bein a good pump minus the unnecessary hole in the side :-). Will order new pump Monday while I am out of town and hope its here when I get back so I can get it back on the road. Thanks for the insight!!!!
