Weird engine start 6.0
Hi fellows,
I think I noticed a weird engine start on my 2004 6.0. Maybe it's just normal, though...
I will post a video, so you can imagine what I'm talking about.

Thanks for help in advance!

Sounds exactly like when you use starting fluid on a diesel engine... Really loud banging and rattling. After it started up, it runs good.

I made this Video when the truck sat for about 3 hours.
Even when I start the truck in the morning, the Glow plug light will stay on longer. What I also noticed is, that the truck won't run smoothely in the first 5-10 minutes after cold start, when I'm slightly accelarating. After the truck warmed up once, it runs like it should.
But I will make a cold start video now. If you can call it cold start, with 100 degree F in my garage...

This is "cold" start this morning:
6.0 cold start
The temperature in my garage was 95F.
The weird thing is, that the glow plugs always stay on for 2 seconds or so. Doesn't matter, if cold, or hot.

Truck has a tune (bully dog power pup) now, but without it, it's exactly the same problem. The hard start, and the bucking while accelerating slightly.
Can't say too much about recent repairs. I bought the truck 3 weeks ago, and what I did, was an oil change (Shell Rotella T6), and I changed the diesel filter and it's housing in the engine bay. Btw: where is the other diesel filter?
Could it be an injector problem? Or maybe the FICM?

did you use an oem filter and cap when you changed the oil. Did it start like this when you got it 3 weeks ago?

Check out and read through our Tech Folder located at the top of the 6.0L forum.
One oil filter is located on the top of the engine, beside that is the upper fuel filter. The second fuel filter is right under your drivers seat mounted on the inside of the frame rail. It is a combined fuel pump, fuel filter, water separator commonly referred to as HFCM or ( Horizontal Fuel Conditioning Module) . Click here for reference on OEM Filters and Will Fit filters, that are not recommended

I'm not sure, if it started like that, 3 weeks ago. But I think so, yes. I wasn't sure, and I thought/hoped it was normal.

I would wait just a few more seconds when glo plug lite goes out, could be one or more Injects,does it happen when plugged in? also try some revx, you dont have to replace the HCFM just the OEM filter also drain the water while your down there,do you run a fuel add ,like diesel kleen ,howes etc?

I didn't ever plug it in, it's over 100 F here in NM.
I don"t use any fuel adds.
Ok, I'll drain water tomorrow.
I don't think it is a problem from the glow plugs, since the problem is the same, when the engine is warmed up.
The bucking while slighty accerlarating, is gone, when the engine is warmed up.

So you think the glow plugs keep glowing, even when the light is off?
