Thanks guys. I'm almost certain every time has some throttle in it though. It's just weird that I have the belt on and letting the clutch out with some throttle when it still wont release... I just need it to sense the clutch and throttle and off I go.
Here's the thing... it seems like the clutch sensor is triggered with the pedal slammed to the floor, I need to do this in order for the engine to start as well. When getting in the car, I push the clutch in to start it, put my seat belt on, and start letting the clutch out while giving it some gas pedal respectively when I notice the brake not releasing. I'll slam the clutch pedal back to the floor and try again, then it works.
I think the problem is in the "clutch sensing" part. What's probably happening is the clutch pedal slips back passed the sensor after starting the car and before clicking the seat belt in. If the belt is on and I push the clutch in the brake releases fine when letting it back out. The clutch is in but just not far enough when the seat belt is sensed.
This really isn't a big deal and I can re-arrange my car starting habits or find a way to auto release the brake without the seatbelt sensor. I'm going to test what I said above later but I think that's what's going on.
Maybe you have to push the clutch in and out 20 times in 30 seconds while clicking in and out the seat belt or some weird sequence like the seatbelt chime elimination...
