LS Swap Help Hey guys, I've got 2004 rx8 that has a 5.3 4l60e swap done to it. I went through all the wiring that was previously in the car and got a psi harness. I got everything hooked up, was trying to get to the point where I can do general maintenance like checking the coolant, oil, and trans. the car was running for maybe 10 minutes, I had hp tuners hooked up to read what the eng was doing. the coolant temp hit 183, the drivers' side 02 was reading high, and then it shut off. the car will not start. ill unhook the battery, let it sit, and hook the battery back up after a full charge. when I go to start it just spins and when I pull the key the fans turn on. as well as hp tuners when I try to read from the obd2 port tells me unable to detect diagnostics protocol. where should I be looking?
