Thanks for the tip. Already did that mod. Everything is fine with the PTU connections. There is no 5 volts square wave coming out of the CAS so the ecu is not sending the 5 volts signal to ground the coil packs trough the PTU. This is driving me insane. I have a spare known good ecu and still does the same. I already tested the CAS in another car and it works perfect. Also the ecu turns on without the ecu relay! Its nuts.??????
