you didn't need to change the pcm and harness.

your going to need to go to the basics. check fuel pressure, injector pulse and spark. Is your passlock working correctly? if your truck uses anti-theft you will might need to do a relearn.

what do you mean when you say the cylinders collapse? what did you have repaired the first time?

My lifter arm broke the first time I had it replaced then two months later it happened a second time but this time it was just stuck in place the mechanics shop told me it had something to do with my cylinders

if it's just a rocker arm problem I would look at the engine oiling system for a problem. The rocker arms breaking or being a problem shouldn't be that expensive to repair. Much cheaper than replacing a motor. And they have had a pretty good record with the 6.0L
