EDIS Module

Hi, new problem with remote start. Finally started w/ tech support however, the starter would not stop engaging. So, that will have to wait. Now when we were getting the tach for remote, car died? Now will start and die in a few seconds. Took the bus to work today and tomorrow too, i guess. A friend said it was probably the (edis module) according to codes. What do u guys think?
Any help is always appreciated. :banghead:
