  First thing I always suggest is somewhat obvious, so please excuse that, but also often the cause. Check your battery for proper connection of both positive and negative cables, on both ends. Also check the engine-to-frame grounding strap.
  
  Last of all, check your alternator output and battery condition. Any unusual drops in voltage will cause your cars modules and sensors to go crazy.
  
  If all that checks out, please check the fusible links (in line fuses) that come off the positive battery terminal.
  
  Last resort, do a "wiggle test" under the dash to see if that activates anything.
  
  Otherwise, there could be a major CAN BUS communications failure, which would require a professional scan tool and a fair amount of skilled diagnostics.

  I replaced the battery (it needed replacing anyway) thats when I noticed the engine to frame grounding cable was not attached to the motor. Reattached it and haven't had any problems. Thank you for your advice!
