Try making the Gen4 harness and PCM work. I think you can do it. :thumb:
You will have to convert your fuel system to returnless or change the fuel rails on the engine to make the Gen4 setup a return style fuel rail.

ok. didn't know about that. I will add that to my list. Thanks.
got the engine and everything looks good. The wiring looks pretty easy. My next question, is the cruise ran through the body ecm before it goes to the engine pcm? If i want cuise to still work, the 5.3 is controlled with the cable and the 6.0 is controlled with FBW. as long as I can get the cuise control "controls" to talk the 6.0 engine PCM, then im good.
The motor has been sitting in the back of my truck since I picked it up. I had a few other projects im trying to get finished. Anyways, I finally started messing with the motor and decided to actually LOOK at it to see if its III or IV gen. So what Ive read is that the IV gens have knock sensors on the side, cam sensor on the front and a gray and white crank sensor. My crank sensor is black and I dont have any sensors on the front or side! conclusion, III gen!! so that being said, will my 2000 body control computer talk to the 2007 III gen computer. Im trying to the correct way to do this with spending the least amount of money.
I am now looking for a t-case. I need to know if the t-cases vary in length/ part number or year. I want to have the correct drive shafts when I tear into this thing. Ive also read that you can reuse the front drive shaft but the rear has to be replaced.
Starting the swap. decided to go with the 5.3 harness and got my pcm programed by NP. installed a hd2 shift kit in the trans a few days ago. The trans looks brand new on the inside. It doesnt even look like it has any miles on it. There is a GM goodwrench sticker on the outside of it so maybe it was replaced within the 60,000 miles the truck was alive! I rebuilt the rear end last night and installed a posi. going to install a 30spline input shaft on the transfer case and replace all bearings and seals while im in there. Im also installing the turbo during the motor and trans swap. messing with alot of stuff at once. I know im raising the chance of something going wrong but I have to get it all done by next week. I'm taking the truck down to NP to have them button up the tune in a week. hopefully I can get everything done in time!
Oh, when I took the spark plugs out of the motor, oil came out of cylinder #2. not just a little, A LOT!:hyper2: It gave me a little scare but the truck had flipped so I'm hoping it is because of that. There was also oil in the intake. none of the spark plugs show any sign of burning oil. and if something was broke in that cylinder then the oil would have leaked down after the motor was right side up. I think when it was upside down oil leaked from the pcv valve into the intake, then when the motor was right side up, the oil leaked into the cylinder that had a intake valve open. Thats my theory. Any takers????
got the truck running. seems to run good. its a little rich but i think that it just needs to be fine tuned by nelson.
That oil in the cylinder happens a lot on roll overs ...good thing you took the plugs out. I have seen a lot of people not pull them and bend rods the first time they fire it up. I always pull them and spin the motor first.
