<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>

Back into a funnel that is suspended above the cavity where the hpop sits

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

Yes oem. The ford tech I talked to told me it should work for testing. The high pressure oil system should be sealed even with the cover off. Unless your concerned about the oil line to the turbo but I believe that's fed off the low side. Could be wrong though. On all accounts

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.

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?

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.

When you installed the new HPOP did you make sure to replace the orings between the pump and block and the STC fitting and branch tube and make sure the plastic plug was not left in the bottom (suction side )of the new pump? Usually ( not always though ) new pumps will have plastic plugs covering the ports to prevent things from getting in them.

fordboy2 07-11-2014 05:37 PM

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

Rusty Axlerod 07-11-2014 05:49 PM

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

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 may want to pull the IPR and spray it out with some WD-40 or similar while working the plunger just to verify there isn't a small piece of trash holding it open. Also, you can read across the coil side of it with a meter. Here's how to check it in the truck. Pull out the middle PCM connector and ohm out pin #2 of the PCM connector (yellow with red stripe coloured wire) to the positive terminal of the driver side battery at key-on/engine-off. (Of course with the turbo out you may want to read right at the sensor) A good IPR should read about 6.0 ohms. Definitely between 3 and 15 ohms.

Here's a chart on the ICP pressure/volts

Yea I know that 84.7 is maxed on ipr and not really good. So the .8v icp voltage is ok, or at least not bad anyways? Looks like.i have everything but the 500 psi to start. Do I do another air test? What about the air coming out of the hpop hole behind the gear last time I pressure checked. At that point I had not cranked the engine at all yet.

Rusty Axlerod 07-11-2014 06:19 PM

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.
