6.0 911... No Start

[lmorgan]

I just changed three injectors on my '04 F-250 PSD. After putting the engine back together, I noticed that the flat ground wire from the back of the engine to the firewall was getting red hot and smoking during cranking. I replaced it and used advice I found here to get the engine running again. It ran perfect for two days. Then I had a single incident on a cold morning where I had to cycle it twice to get it to crank. It also puked the smell of raw diesel out the exhaust, but ran fine after that. No clatter, no miss, no rough idle. I tried to start it yesterday and it won't even attempt to crank. It just turns over. The oil gauge says I have oil pressure. Fuel is getting at least to the filters. It's a hundred bucks every time I have to tow it to the dealer and quite frankly, I'm at the end of my rope with this thing. In one year I've replaced the EGR and Oil cooler, then deleted the EGR, replaced another oil cooler, replaced the IPR, replaced the Degas bottle and now the injectors. This truck has 120K. My '95 7.3L has 235K and hasn't even hesitated.

Is there anything I can do before I drag this thing back to the dealer for most costly analysis? This forum has been good to me in the past. I hope it can help now.

HELP!!!

If you are the do-it-yourself kind of guy I suggest investing in a Autoenginuity or similar brand scan tool. With this you can monitor systems and censors to correctly diagnose problems and take a lot of guess work and trips to the dealer out of the equation.

As far as your "new" problem, my first guess would be the FICM.

^^^^Good advice!!!I would agree it sounds like the FICM.

Thanks for the advice. What kind of cost investment would I be looking at in a scan tool? Is the FICM in these 6.0s prone to failure without warning like that?

Scan tool- No idea..

FICM failures out of the blue- Yep, especially with crappy voltage (such as a bad ground..)

A military diesel tech friend is loaning me a scan tool tomorrow so I can pull codes. If I pull the codes and he's unavailable to read them for me, is it possible to post them here and get some guidance? Also, since I last posted, I noticed that when I try to start it, there is no oil pressure. Originally I thought there was. I'm thinking that it may be the HPOP or the IPR. Anyone ever have that problem in the past? I know I blew the IPR once in the past when I replaced the oil cooler and had the same no start issue.
