Thanks hey you. I bought electronic cleaner and sprayed heavily on all connections and doubled up on grounds cleaning paint off them. The other thing I should mention is I watched a YouTube video before I wired in the extra injectors and they didn't change the PCM when doing the same swap. Oh also there are no oxygen sensors on the truck or exhaust. I just want to try all I can before buying a computer. Will a junkyard one work off of a truck with a V8 ? The NO BUS condition is still there , the engine turns over but there is no spark or sound of fuel pump. Any more suggestions would be greatly appreciated.

 

What are you working on??

 

1999 Ram 1500 I installed a 5.2 from a 1997 Cherokee

 

You need to have the PCM flashed for the V-8. Of course, the no bus error is going to complicate that. May have a pinched wire somewhere, or, a bad sensor. Crank sensor comes immediately to mind, as you swapped engines.....
