Long story short , I purchased this car not running. The owner blew out the clutch then over rev the engine spinning a rod bearing. I have replaced the clutch and the engine. ( I do this for a living ). Every wire is plugged up, all fuses seem ok and I have tested all relevant relays but I’m getting a rapid security flash suggesting the key may have lost programming. I hooked my autel computer to the obd and I can’t connect to the PCM. I next probably need to check my voltages and grounds coming out of the obd but don’t know what pins require what ? Keep in mind the transmission was pulled out over a year ago along with the pcm and placed in the trunk once it was determined the engine was bad. Any help greatly appreciated.
