How did you know this was the issue? I'm having a similar issue with OP. The butterfly opens, fuel pump primes but when turning the key the dash goes black and I just hear a clicking. At first I got the lockout display but was able to track that down to some loose grounds.I had to do a clutch relearn to get mine to start, But I used a push button start until I and a GOBLIN BROTHER FIGURED IT OUT.
99% him fixing it 1% me
Also, my OBDII works great and I just get codes for the A/C. It looks like in hptuners I can poll most of the sensors.
