Been a while since our last post but the news is good! Finally have the beast running.
Here is the short version of the last 3-4 weeks. At the much anticipated initial start-up, I ran into some trouble. She lit right up but only wanted to enter life as a 4 banger! I realized that the even bank was not running. Well since I reworked my own harness, I suspected that I had made a mistake somewhere. So I ran the pin outs several times, read the woes of countless others trying to fix similar problems....all with no solution. I decided to source another harness and just lay it in place to see if it would run right. Guess what? Had the same problem!!! The good part was that I felt like the problem wasn't in my harness rework. Then talked to a few other people that I know who I regard as successful and knowledgable in the LS conversion world. When I ran the pin outs (3 times!), I used the pinout table that came with the GMPP harness. (Also the info I used when re-working the harness). The problem is that the table does not include specific coil/cylinder locations (i.e. 1-8). Sooooo when I originally re-worked the harness, I reversed the even coil bank. Then to further complicate (and aggravate!!!) things, when I did the layover with the 2nd harness, I inadvertently connected the coil pack harness backwards......I know, go ahead and kick me in the rear! Moral of the story, get COMPLETE pin out info if you want to tackle this job! Thankfully my wife (who helps me TONS) asked the simple question, which led us to (almost immediately) spot the error. Flipped the coil pack harness and Voila! fired right up, on 8 cylinders! Then I went back to my original re-worked harness and swapped the coil leads at the bulkhead connector and re-fired the engine. Ran perfectly! What a relief! Took me a while, and the help of good folks, but I got it running.
Let your ears enjoy the video! I know I was like a kid on Christmas!
Now we can get on to the rest of the build.
