First time posting here, sorry if its not formatted perfectly or anything. I just swapped a 05 5.3, with an NV3500 into my 1990 Sierra, followed LT1 website to make custom harness, and fuse block. The problem is that my engine will crank, and will easily start with starter fluid, but dies soon after, (possibly due to the fact that i have to disconnect the MAF to use the starter fluid). Ive checked all the continuity and powers I can think of, injectors and coil packs especially. I wouldn’t normally post this kind of thing, but I have to head back to college in two days, and I’m really on my own here, not a pity story at all, just really need any help I can get.
