Here's the story, I bought this truck for cheap because it would only crank and run off the cold start injector. Somebody has just swapped this used engine into it, probably from a different year. I followed the wiring diagrams and yada yada, come to find out , the injectors that are supposed to be in it are the low resistance injectors and this one has the high resistance ones in it. I don't think the wiring harness and ECM was swapped (because that would have been way over the head of whoever did this engine swap) and all the pins, wire colors and stuff matches the info from alldata.
