Haven't started in a long time, no rpm signal. Help!
 

Hey i have an fd that i haven't been able to touch for a year. I had taken the harness and sent it to a shop with a fresher harness to combine into one single turbo harness for my pfc.

Right now i have the motor turning freely, but no rpm signal on the tach but i am getting 220 on my pfc. It is not coughing or catching at all. I feel like its in some type of limp mode. I only have necessities connected atm..tps,cas,inj's,ign coils,O2. 2 engine bay grounds and one next to ecu are all checked and grounding properly. Im stumped.
