Dug into it today. Replaced the Tps, nothing different so I replaced the coolant temp sensor nothing. Feeling very discouraged I turned to nick who was a giant help and he told me to do the mpi and ecu and still same problem. Thanks to iceminion and Kerry (talonracer) I have it pretty much traced back to things not getting power like a short or something so ima try another battry and try back probeing everything and see if anything comes up
