Diesel Posted September 19, 2014 Share Posted September 19, 2014 (edited) This weak the truck started starting hard when it is cold. Truck sits for 12 hrs between driving. It will stumble at about 500rpm for a couple revolutions then build up to normal idle rpm and runs fine. If I shut it off and restart it starts fine. Ambient temps at startup have been between 69 to into the 80s. Any ideas? Edited September 19, 2014 by Diesel Link to comment Share on other sites More sharing options...
dorkweed Posted September 19, 2014 Share Posted September 19, 2014 How many miles??? How many miles on the injectors???? Sounds just like my Buds '03 when he needed new injectors............once he got her running, she'd start up fine until it sat again overnight. 1 Link to comment Share on other sites More sharing options...
mopartechnician Posted September 19, 2014 Share Posted September 19, 2014 You have too much injector return 1 Link to comment Share on other sites More sharing options...
MnTom Posted September 19, 2014 Share Posted September 19, 2014 You have too much injector return Exactly. You need injectors. 1 Link to comment Share on other sites More sharing options...
Diesel Posted September 19, 2014 Author Share Posted September 19, 2014 That's what I was afraid of. So I have 2 questions........ How long till it completely craps out or I damage something? How hard is it to change the injectors? And a 3rd question. How do I change them? Link to comment Share on other sites More sharing options...
mopartechnician Posted September 19, 2014 Share Posted September 19, 2014 They wont hurt anything, I will just have hard starts espcially when it gets cold. Not the hardest, but there is a lot of things to know when you are doing them. Mainly torque values, tips, and tricks. I have done hundreds of them so I have figured all them out with trial and error. Make sure you get bosch remans or if you can afford them, bbi injectors. Do not get reman bosch or anything that is under 340 an injector. They are cheap rebuilds and you will end up paying for them. If you need help finding injectors, let me know. 1 Link to comment Share on other sites More sharing options...
mopartechnician Posted September 19, 2014 Share Posted September 19, 2014 You could actually torque the connector tube nuts to 37ft/lbs. If they are not tight, they will cause rail pressure to get past the tube and go to the return. 1 Link to comment Share on other sites More sharing options...
Diesel Posted September 19, 2014 Author Share Posted September 19, 2014 OK. Thanks. I'll check the nuts Tourqe and if that isn't it I'll be able to run it for quite awhile like it is till I can save up for new ones? Link to comment Share on other sites More sharing options...
mopartechnician Posted September 19, 2014 Share Posted September 19, 2014 Yep wont hurt anything Link to comment Share on other sites More sharing options...
MnTom Posted September 20, 2014 Share Posted September 20, 2014 Eventually you will get to where you need to use a starting aid (ether) or need to plug it in to get it started. If you use ether or anything like that disconnect your grid heaters! Link to comment Share on other sites More sharing options...
mopartechnician Posted September 20, 2014 Share Posted September 20, 2014 One tiny shot of ether wont explode. I use it all the time to bleed injectors. But if you are worried, pull the signal wire off the relays Link to comment Share on other sites More sharing options...
Diesel Posted September 25, 2014 Author Share Posted September 25, 2014 I havnt been able to check the nuts yet, but it seems to be getting worse. It did start normally a couple times, like when I was gonna show my wife, but then it started up again. This morning it started and idled at 500 for maybe 5 seconds then jumped up to 8-900 then started bouncing around 7 to maybe as high as 1100. I ran around to exhaust and yep, smoke. Another thing, something sounds like it's making noise around the injector pump. Sounds like a tapping. So, definitely injectors? Or injector pump? Or both?

Moderator AH64ID Posted September 25, 2014 Moderator Share Posted September 25, 2014 The #1 injector line can make/transmit noise in that area so it could be that. My dad's 06 is getting injectors today. It started 2 years ago with a rough stumble/idle and white smoke. It always starts, but often it's ROUGH. A month or so ago the mileage started dropping and the injector rattle got louder, so now it's getting marine bodies and DDP 50's. Link to comment Share on other sites More sharing options...
Diesel Posted September 25, 2014 Author Share Posted September 25, 2014 Yup. I was hoping for something else. Link to comment Share on other sites More sharing options...

Just under 214,000 miles on the OEM injectors now and still getting 19-21mpg hand calculated!!! Hoping my religious treatment of diesel fuel with 2 stroke oil will buy me a lot more time on the OEM's. Link to comment Share on other sites More sharing options...
mopartechnician Posted September 26, 2014 Share Posted September 26, 2014 I got 223,000 on mine. Going with bosch remans. Cant afford bbi. Im only getting 16 so its time for injectors Link to comment Share on other sites More sharing options...
