Another cold start thread..

Truck is a 07 6.0, 160k miles, sct tune, new 58v ficm, studs, egr delete etc.. brand new batteries a month old. new glow plug module.It literally will not start in the mornings unless its plugged in. I have to hold the key 5-10 seconds then when it fires, keep holding it while its running for another 10-15 seconds to keep it going. I run rotella 15w40 with rev x and no change. When the motor picks up after i let off the key, it pours black smoke for 15-20 seconds, revs up fast to 1000 rpms then idles normal, has slight hesitation until upto temperature then runs perfectly fine with no sign of injector problems. Could this be a glow plug problem or injectors??? It even does it with no tune but not as bad, im thinking glow plug

Sounds like you've got some glow plugs bad. Or the harnesses are no good

Exactly the same issues I had. Hawgdoctor checked it out for me found 6 glow plugs no working correctly, but my glow plug module was fine. Putting the new ones in today.

Well then thats a good thing that its not injectors or something major. Is your truck tuned? Would it pour black smoke then clear up?

Yup. I run tsd's spd w/out early lock up and idp's x-street for my 175's. hawgdoctor is putting the plugs as we speak. Bill and Chris agreed this should solve my issue.
