After a new injector harness, HPOP and lines, ICP, IPR, glow plugs, and valve cover gasket, I’m finally taking those injectors out putting new cups, o rings, and shims!
7.3 Non of my injectors are working. I have replaced cps, irp, icp . My hpop is full. Fuses good relays replied. Will start with starter fluid then die after burns off. Took the idm apart looks good no water. Fuel is getting to the bowl. All new parts oem. Good rmp signal. What could be stopping the injectors
I just got done doing o rings, wish I'd known. Fixed my stalling problem but now the longer it sits there longer it takes too start. Thanks for the video very helpful.
yes, it is the same. If it has high miles & you have never changed the O-rings, I would suggest you change the O-rings also, internal & external, along with the internal springs, it will save you a headache later on down the road, along with the shim kit for the solenoids. I have done three 7.3L powerstrokes already, 1996, 1999, 2002, I have never had to buy new injectors, ever. They are tough but need TLC, maintenance is key.
I know this is an old video, but hopefully this will help someone! Think about what is being worn on the injector! The poppet valve..not the solenoid! If the factory clearance was .004 new and now, let's say it's. 002! Then shimming the poppet valve only, by .002 will bring it back to specifications of .004! The solenoid didn't move or wear, so why would you need to shim it? I have watched several videos where they shim the solenoid, but once again the poppet valve is the part that is being worn! If someone out there sees this differently, please comment on what I'm not seeing? Thanks.
What about the Solenoid clearance? The armature plate is now that much closer to the solenoid, sounds like a great idea until you run the injectors on a test stand.
That's why you shim the solenoid as well, you're supposed to shim the solenoid .001" more than the armature to accommodate the excess length between the top seat of the poppet valve and the armature PLUS top side poppet wear.
@@MrRonny420 none, but I understand the concept... idk how much clearance there is or should be between the solenoid and armature but it can be compensated for. It's just a matter of whether the gap between the two is too great after shimming to function, but other than poppet replacement theres no other way to eliminate the excess travel caused by wear.
it could be you do not have enough oil pressure you can change the o rings with out removing the pump the lest little Nik in the o ring will effect the oil pressure '
I have a '01 7.3 with about 250,000 miles on it. It seems to stumble and run rough at 1,700 rpm at 40 mph, very noticeable going up a slight grade. Starts and idles good, smooths out above 1,700 rpm. I will give this shim procedure a shot. Thanks for all of the details you showed in the video.About how many miles is on the truck in your video?
