    Everything is interrelated. There could be one part of the system that has failed or it could be a whole bunch of little things. If you do not know much about cars, then I would suggest to save yourself a lot of money to simply take it to a GM dealer and pay them to hook it up and give you a list of problems. Otherwise it is hit and miss.
