While I have no issues rebuilding injectors from my Jimmy 2-stoke or old Ford compact diesel, I've never wanted to try these.

Anyway, for a reference sound, I looked through my videos, and the best ones to show are these. The in-cab was with the door closed, unfortunately. It also shows the difference of the faster running 6.4L starter. In both, you can hear the early production "bump."

Yeah definitely have learned my lesson here. Don’t rebuild an injector you can’t pop test prior to install . It was so tempting though seeing the other guys getting by with it but I reckon lessons been learned here.

Will replace my current starter w one of the 6.4’s my plan was put the stress excess cranking cycles until the truck runs then swap it with the new one.


As far as the early production bump , not sure what you mean in comparison to mine?

We’ll just placed the order for some Motor-craft Injectors . Should be here in a couple days . Will update everyone when they’re installed.

What did you do with the old injectors and what was wrong with them? The reason I ask, is can you try to put them back in and see if truck starts? Are you sure you have the correct wires going to the correct injectors?

I wanted to do that but unfortunately I’m always a hind sight kind of person. Instead of doing what you’re saying, which sounds most reasonable. I tore down those old ones, put those nozzles on my new rebuilt injectors thinking the nozzles specifically were the issue. So in doing so they all got separated from their labeled bags and taken apart … itd be an understatement to say that there have been ALOT of learned lessons while working on my truck.

I had a 06 450 6.0 that I did head gasket and head studs on. It started after killing the battery 3 times but when it started it the engine didn't "wake up" right away it would take 4 or 5 seconds of cranking then rpm would come up very slow to idle. It would idle fine but petal to the floor would take a full minute to reach 60mph... Long story short it ended up being the injectors being damaged by the machine shop using a wire wheel on them... Replaced all injectors and it ran like a dream. When you rebuilt these did you do it in a super clean environment? Like clean room cleanliness? Lint free cloths etc.

I have used a wire wheel to clean injectors many times, ...you don't just lean into the wheel tho -- that would be a good way to damage the little holes on the tip

Sorry to hear they were ruined by the shop, hopefully they owned up somewhat to it.
Hopefully she will run like a dream now, that would be great lol so as far as rebuild cleanliness I feel like I was very careful rebuilding, wore gloves, upon disassemble (they were dirty from prior owner) I cleaned injector assemblies by soaking in a cleaner then placing in a ultrasonic cleaner, used gun cleaning cloth as well as cotton ball style material to wipe dry and oil the parts after that. torque the body and solenoid bolts and placed in individual ziploc bag until all 8 were rebuilt. I then swapped all straight from bag into truck which is what blows my mind about the lack of success with the effort put in. I will say though the guy I purchased the used injectors didn’t really keep the injectors clean or cared for much. They were in a slam packed in small card board box with SOME dirt/debris so maybe the deal was doomed from the get go as too good to be true due to that lack of care (I purchased the used injector set and Stock turbo for $300, turbo needed extensive cleaning of vanes from corrosion)

The high pressure sealing surfaces need to washed in lubricant and assembled -- never use a cloth or anything else on those surfaces

save the cloths for the outside of the injector

A high powered magnifier will show how much crud the cloth or cotton will leave behind

Yeah unfortunately I have no doubts that I messed up somewhere along the way if not the entire process. Using the cloth being one of the many mistakes . I greatly under estimated the fine tolerances a diesel injector could truly have being the greatest mistake I reckon. Live and learn. If the truck starts tomorrow I’ll be grateful to move on from this chapter as my bank accounts hurting as well as my desire to work on the truck any further lol

Hello All,

So as the title states, I am experience a No start issue with my 04 6.0. The truck ran great before I did all this work which is what sucks, I DID have intermittent low circuit #7 injector (ended up being a corroded pin) and I also had bucking when in OD, everything I read on these forums stated fuel injectors. So I purchased an injector rebuild kit (new springs, seals, rings, metering ball), new stock nozzles, and new spool valves. I rebuilt a set of used injectors I purchased online, did the blue spring update, replaced oil rail nipple cup o rings, replaced HFCM as the one installed was original wasn't showing signs of age but wanted to reset the cycle of the entire fuel system and go another 180k. Did not touch stand pipe as I didn't think this style would be prone to failure as the updated versions were but I currently have two on order. Changed the oil and filter and fuel filters (all Ford filters only) Went to start and unfortunately no start, sounds like it wants to but does a weird fast crank and sounds like some cylinders are firing off but it just never actually starts on its own. Cranking parameters read as follows:

Fuel 60 PSI,
FICM Sync-YES,
FICM VOLT 48.5
ICP Volt 1.9-2.0
ICP PSI- 1400-1520 +- 50
IPR 44%
IPW ms 1.14
CRANKING 150-250 RPM

Further troubleshooting, ive tried putting a known good ficm in thinking it could've been my ficm still no change actually got a U0306 code when installing that FICM. Pulled fuel lines from bowl to banjo bolts inspected and sprayed with air thinking maybe one of them could've been clogged with debris, everything from what I saw was good. Disconnected the suction and return line from the HFCM and put fuel hoses in a fresh container of fuel thinking the time its been down any sediment settled in the tank but even with fresh fuel it didn't change the no start issue. I have a feeling ive wasted my money on rebuilding these injectors and should've just gotten the Motorcraft injectors out the gate instead of trying to save money but im worried if I spend the money on them at this point and im in the same no start situation that'll hurt bad lol based on the IPR % and ICP pressure of 1400-1500 would you all be in agreeance the HPOP is functioning properly? I am going to be transferring in the next few months so im at a point of having to take it to a shop to get it diagnosed/repaired, Thank you all in advance for the answers/insight.
It sounds to me to be oil pressure leaking somewhere if you have a real fast cranking. I think it’s your oil rails

Well, after installing the Ford remans the trucks alive again, cranked a fraction of what it did prior and fired right up. Will put valve covers back on button everything up and test run and get to see how it drives after replacing leafs and shocks front and rear so excited to have a good running truck again! Thank you all for identifying and affirming it was injectors. Anyone know where I could’ve gone wrong w the injector rebuild? What should I do with the $600 in new spool valves , nozzles and internal parts other than a terrible reminder of being cheap biting me in the *** and costing me way more in the long run lol

You could sell them on ebay for cores. May be able to recover most of your money if you explain the details.
