    Hard start, not fuel return[?]

    Hopefully a conclusion on this thread, and info for anyone who comes along to read after: She just started up from overnight cold, ambient temp about 65F, with 5 seconds on the new glow plugs. I still have the auto controller disconnected using only manual switch for now, but still seems like...

    Picked up motorcraft zd28 plugs from O'Reillys. They look exactly the same as the plugs the shop installed; they do not say "beru" anywhere on them. Package says made in germany

    Hard start, not fuel return[?]

    Thats exactly what I did, just pulled the pink wire off the relay solenoid. Im a bit apprehensive about putting the new glow plugs in until I've replaced the injectors since I think I read that dribbling injectors could damage the plugs or something. I'm just paranoid at this point and I've...

    Just probed everything in the system. Glow plug light comes on as intended every time relay closes. Battery voltage goes to glow plugs every time the manual switch is closed, and every time the auto controller signals. I've disconnected the auto controller from the relay for now and will put the...

    Zd1a was superseded by Zd28, but yeah if theyre counterfeit either way, that just ****** me off further. I see in the images on rockauto they say beru. Just figured they may have changed manufacturing as I've seen other products do didnt find the 90 dollar kit in their store, but if the manual...

    they will -always- say beru? yeah no "beru" anywhere, and they look weakly laser marked with the numbers I'd have a hard time swinging the $225 for wes's wires, but I guess I'll have to trace down all the wires already in the truck at the very least... and now I'll be skeptical of any source...

    dang. and I assume, if the thermo-controller was working, and they didn't know, they would have been firing them in conjunction with the normal controller cycle, so potentially longer... my only remaining concern then is that it seems like people were replacing the glow plugs often before I got...

    hm. maybe my phone camera or heat discoloration? either way thanks. I guess I can put in yet another set of plugs and see what happens. real tired of spending money on this but I should have checked the plugs earlier. just assumed it wasn't the issue immediately after the shop replaced them...

    It would feel about on par for that shop if they're counterfeit... Here are closer cleaner pics of both sides Thanks for the info on the bosch plugs, I've seen them referenced before, but seems every other opinion is good or bad for everything

    Sorry to be making a novel out of this, and I appreciate everyones time and help. From a folder i was given with the truck, looks like two owners ago, in 2012, replaced all the glow plugs and controller(s) with the dieselRx kit, and installed the manual switch. previous owner bought it around...

    Is it normal that they're all wet/oily? 3 three pictured right, I had wiped off, then set them back in but didn't screw them before removing again for photo. the left one in the photo, I didn't wipe off at all These are from cylinders 1, 2, 4, and 7, for no reason other than ease of access...

    ok. just pulled 3 of the glow plugs. they're all new ZD28. they're all bad. I guess its nice to find 'the problem'. Not nice the brand new plugs a shop charged me an arm and a leg to replace apparently all went bad immediately, and for reasons yet unknown... although, even on hot days the...

    Just gave it a "controller" cycle, then 2 additional 10 second hits from the manual switch. Cranked for 10 seconds, then waited, and 10 again, not even a cough of an attempt to start. It does lope a bit sometimes I'm realizing, but it cranks very fast and strong. here are photos of the controllers

    They're spade style. The shop that replaced them made a big stink about only using the oem motorcraft plugs, from their oem supplier or whatever. I havent pulled them out, but my invoice says ZD28. They also replaced the control unit with a motorcraft one, DY861. I've let them do their full...

    Forgot to mention this, original seperator started dripping on a drive in the middle of all this troubleshooting/repair, so I did bypass it. I'd pulled the ring to drain a couple times before, and it didnt seem to leak at all until one day when it started leaking a lot. And not from inside the...

    glow plug light comes on for ~8 seconds, then goes off ~4, then on again ~2, then off ~4, then on ~2, then off... with the solenoid clicking each time. Doesnt click out of time with the light. Appears to be working with the controller I just tried the same cycle again manually with my wired in...

    Hi folks, first post, although I must have read about 200 over the past several months. this truck is the first diesel I've owned, although I've worked fairly extensively on a range of gas autos. Truck in question is an early 86 f250, stock NA 6.9. ODO currently reads 49,000. by the interior...
