6.0 shut off, Now hard starting, running rough

Hi, I have been a member of the forum for awhile, I've done alot of reading (lots of good info on here) but this is my first post.

My buddy is having some problems with his 2003 6.0 He recently bought the truck at an auction with 2 bad injectors. I replaced the injectors for him and it ran great for a few houndred miles. The other day the truck just shut off on him while driving down the road.

Now the truck is very hard to start and smoking alot of dark grey / black smoke. When the truck finally starts it runs very rough, wont hardly rev past idle, and wont stay running for very long, and still smoking alot after engine is running.

I recently got the Auto Enginuity software with the Ford enhancement and am going to hook it up to the truck tomorrow. Does anyone have any ideas to what the problem could be? Anything specific to check with the AE?

The truck does not have a chip / programmer in it, it does have the EGR delete, O-Ringed heads, Arp studs. The FICM was replaced recently also from what the guy at the auction said.

Any help / ideas on this would be great.

Thanks

mine did that found out to be two injectors leaking air into the system and was causing the engine to die. Try checking for air into the system after you scan it with your ae.

I am just curious. How did you figure out it had 2 bad injectors? My buddies truck is in the shop right now because it was running rough and white smoking and the guy is saying that 3 injectors are bad. Wouldnt there be some type of codes?
