Extended cranking, fuel system tests.
It has never thrown any codes until no start condition. It is low rail pressure while cranking. That is the only code that comes up. I am kind of at the point, am I going to waste time buying 4 injectors? Or put the failed used ones back in to do more testing? Seems kind of silly. But even... -
Extended cranking, fuel system tests.
Not sure what I am going to do yet. LPFP I have 62 psi while cranking. Hard to imagine there can be any issues there but who knows. Still trying to decide what direction to go next. Actually thinking more about the VCV, I never got a click or a buzz or anything. Seems dead to me. But there... -
Extended cranking, fuel system tests.
Okay, Injector test results. 1 failed miserably, IAQ test I think is what he called it. The computer cannot accurately control the injector. 3 more are what he called in the yellow, meaning they are not always responding accurately. Nothing that would cause a no start condition, so I need... -
Extended cranking, fuel system tests.
Great info, thank you. Now I don't have to go searching for it. I feel like I want to replace it. But then I also want to do glow plugs and valve cover gaskets and who knows what else, but really I don't need any of those things. Slight leak on the driver's valve cover gasket. Actually... -
Extended cranking, fuel system tests.
Injectors are out, look better than I expected. Off they go for testing this morning. I suppose the best I can hope for is to have 3-4 bad ones that bypass enough flow to prevent the rail pressure from climbing. Pulled the PCV, pressure control valve as well because I was there. Looks... -
Extended cranking, fuel system tests.
LOL true. I always have the weirdest stuff happen to me anyway. I mean most people pull the volume control valve and find rust or metal shavings. Nope, not me. Most people get a low fuel pressure warning. Nope not me. Most people get an injector code. Nope not me. Honestly should have just... -
Extended cranking, fuel system tests.
Hope it helps someone. Been quite a journey so far. Can't believe it is so hard to find info. Consistent info. or the typical follow ups. I hate that, no solution ever posted. Can only imagine it gets junked or sent to the dealer. I am back and forth on just buying injectors or having these... -
Door strikers = best $100 I've spent on this truck
No doubt, so what is the real problem? Body mounts? Weather stripping? I have a rattle or squeak that these would fix but that is not a very long term solution.- Tiha

Extended cranking, fuel system tests.
After all that it would indicate the HPFP has failed. Whether it be an inlet suction valve stuck open and allowing fuel to just recirculate, or catastrophic failure, don't know yet. I am still going to pull the injectors and have them tested, but it looks like I am headed back to my original... -
Extended cranking, fuel system tests.
PCV testing, Pressure control valve. So the way this works, when you turn the KOEO it is open to allow the rails to fill with fuel, During cranking it shuts the flow off so the rail pressure can rise. If it is stuck open the rail pressure will come up slow, not rise, or rise but be too low... -
Extended cranking, fuel system tests.
Okay, to update and share what info I can. VCV, volume control valve, or valve on top of the pump. Seems like half these things go by different names. Anyway, KOEO I get no noise, rattle, vibrations, buzz, anything out of it like I read I should. So don't expect that. Did test that I have... -
Extended cranking, fuel system tests.
I never looked at the injectors that close, is it possible to get injection pressure back into the return line and blow the return lines off? Or is it just a mater of available fuel being diverted to the return? He said that an injector may not miss or act funny in anyway. May pass every... -
Extended cranking, fuel system tests.
Friend of mine just called me back from the diesel shop said he had to get his mind back to the Ford mindset and after talking with his co workers. One of the reasons I hate calling him is because they see the worst of the worst. They have dealerships tow stuff into them when they can't figure... -
Extended cranking, fuel system tests.
I always have too. Ordered the 30mm crows foot for the DRV or pressure regulator on the Left rail. Should be here today. Figured I need to test it and inspect it to know for sure. I had used an air hammer to break it loose. Figured I better get the right tool to tighten it properly when I get... -
Extended cranking, fuel system tests.
Had someone tell me to just replace the suction valve, but really with all of the horror stories I have read probably time to just throw a pump on it. Seems like the RCD CPX is very popular. I need to research it some. And yes I am thankful that I don't need to do a whole system. This whole... -
Extended cranking, fuel system tests.
I guess I need to look for a video or something. I didn't try to force it past the injector hold down, maybe a little push and it would go. Thank you. -
Extended cranking, fuel system tests.
It hard to diagnose over the internet. Whether it be terminology, or understanding, or just not looking at the same things everyone else does. Just like in this case. I can find one person that explained conditions that matched mine. Everything else I find they all have metal shavings. Mine is... -
Extended cranking, fuel system tests.
Well low pressure is 62 psi per maual gage. Still won't start. Rail psi not coming up. Pulled intake again. Pulled flow control valve. Still clean. Pump full of fuel. Found this. "quick tip here. The typical failure with cp4 pump is a bad valve seat on the Intake non-return valve (suction... -
Extended cranking, fuel system tests.
Tried to move the truck last night. Would not start. Now I am pissed. Was running, pulled return line to try and make my own pressure adapter. Which I failed at. Put line back on because I can't keep waiting on this stupid adapter forever with this thing in my garage. Now I can't get the... -
Extended cranking, fuel system tests.
I was supposed to have a fuel pressure tester adapter by now but it hasn't even shipped yet. I tried to build one. Looks like the upper fitting is a 12mm found a quick connect that works on 1/2" or 12mm. It seems to snap onto the fuel filter just fine. But the Steel end, 12mm, to make the...
