\I had found a thread with someone having the same symptoms as me. He changed the fuse box and had success. I thought wiggling the fuse box when no crank appeared and 3 times the car came to life each time i wiggled the fuse box. I took the fuse box from my parts car and then went to remove my fuse box and one of the connectors wasn't clipped all the way. Since I clipped that plug the car is starting every time. I am not quite convinced its fixed but maybe if I have a no crank or the P not lighting on the J gate for a month or so I will say its fixed. Thank you all for the input. Anymore input will be appreciated.

Update! Just to put a nice conclusion on this issue, because I hate reading threads that just stop with no fix or update. My car had a intermitten no crank. So when the car would not start, the would be no crank (not even a click on the starter), if you listen the fuel injection would not prime, and the P on the J gate wouldn't be lit up. Also the message center would say low brake fluid, transmission fault, incorrect part fitted, Trac not available, and sometimes the climate control screen would have Er and beep. Also under this condition if you hooked up a OBDII scanner the scanner wouldn't connect. Thus understanding this if was a CAN bus issue. Turns out it was the main fuse box under the left front side of the hood, had a short in it. I have replaced it and it has been working great. Many starts and stops with no issue. Thankfully I fought this issue for almost 2 years myself. Took it to 3 mechanics who all were stumped. I thank this forum because it really gives me the confidence in owning these cars and fixing them.
