If your referring to the ICP reading KOEO it's at 0 right now.
<p>Knowing the ICP volts at KOEO lets us know if the ICP sensor is biased but you bypassed that by attempting to start with the ICP unplugged. If you are cranking with the turbo removed where is the oil going for the turbo oil feed?</p> |

I'm not sure how that may affect the supply of oil to the HPO reservoir. Are the IPR and HPOP you bought OEM?

The IPR valve is only an actuator that defaults to the nomally open position. This means it exhausts most (or all) of the high pressure oil pump output to the crankcase sump when it's not energized. When the engine is started, it is COMMANDED by the PCM to increase duty cycle (to close), in order to increase ICP as needed.
What is the IPR reading crank-no start? ScanGauge code- range is 0% to 85% IPR Duty Cycle 07E0221434 046285140634 3008 0DCA03E8000A IPR % Also, here's the code for ICP voltage. Many of the guys here would rather see that number. The range on it is 0.0 to 5.0 volts I believe ICP Voltage (Volts) TXD: 07E02216AD RXF: 0462451606AD RXD: 3010 MTH: 004827100000 NAM: ICV |
Also, a quick check of the fuel pulse width can tell you lot. Here's the code for it:
Fuel Injector Pulse Width (microseconds) TXD: 07E0221410 RXF: 046205140610 RXD: 3010 MTH: 000800010000 NAM: FPW 0 - 50000 (μ seconds) Fuel Pulse Width range If it's "0" when cranking the injectors aren't firing. You must have cam, crankshaft, and FICM sync for this to read. Should be somthing like 500 if everything is ok. |

Also yes the ipr maxes out at 84.7 while cranking unless the icp is unplugged. Then it's 64. Something which I assume is the default cause the ICP also read 1467. Really there has not been any change in it the readings have been the same before replacing the IPR, hpop, stc fitting. Along with associated o rings. I will remind that when I got the truck 2 weeks ago it would fire right off cold and start but with a extended crank time when warm. I replaced the drivers side standpipes and dummy plug started drove it about 10 to 15 miles and had it at about 2000 rpm in the driveway making sure the air was purged when it shut down. Just like you turned the key off. I checked the fuel switch in the kick panel and it seemed like it clicked. I do have fuel in the fuel bowl and it fills at a rapid pace. Since I have not been able to get it started and never seen above maybe 60 icp. That pretty much sums up the history of what's been going on. When I air pressure the system it seems to have no air coming from either valve cover. I was also.ttold that there is probably nothing in that area that would cause it to shut down like that but that's just onfo.i have read on the net. So maybe not.

I replaced both o rings(branch tube and block) yesterday when I put the new stc fitting in. I did not change them this morning though. I removed two red plugs out of the hpop one in the bottom of the hpop and one at the Stc fitting.i also thought I would dump some oil into the hpop through the plug on top after the first few initial cranking sessions and when I removed the plug I heard a little air escape and had oil flowing out the top so I just put the plug back

Well. I triple checked the FPW codes and I'm sure I've used that one before. You may want to double check your input just to verify. If FPW is 0 it not squirting fuel. Cam and crank are next to check. While they are separate sensors they are combined and reported as SYNC on the ScanGauge. I think IDS can break them out sperately.
Sync (1 = in sync, 0 = not in sync) TXD: 07E02209CD RXF: 0462050906CD RXD: 3701 MTH: 000100010000 NAM: SYC Also, you can have a sync fault from extended cranking and no start. It can be cleared by disconnecting the batteries for a few minutes with the headlights switch on. (Hard reset) One more thing to check is vRef voltage. It's the common power supplied to ALL the sensors. Should be 5v or close to it. Low migh indicate a power issue to/from the PCM, a faulty sensor or wire harness. VREF= Voltage reference TXD: 07E0221155 RXF: 046205110655 RXD: 3010 MTH: 000133330000 NAM: CVI |

Ok icv is . 23 and the few is 0. And yes I have ficm sync. And this is all while cranking. As far as the injectors firing they won't fire until we see 500 psi at the ICP correct?

Sorry man, I just breezed right by this. You do need .8v to start. For what ever reason it still not making sufficient pressure. Unplugging the ICP sensor should have allowed it to start if it was just the sensor being wrong. The high IPR number means it's closing the valve as much as possible.

You posted ICV as .23, not the .8 necessary to start. This can get a little confusing on the net sometimes. I added an IPR check to my post above on edit. Should have just made a new post.
