What makes my 1996 Cad Seville SLS hard to start during below 40 degree temps besides battery problems.


Asked by Jun 08, 2014 at 10:44 AM about the 1996 Cadillac Seville SLS

Question type: Maintenance & Repair

Just won't start during 40 or lower degree temps. But will above these temps.

1 Answer


Could be your air charge temp sensor reading wrong or engine coolant temp sensor also reading wrong, they might not set a code cause they are operating but just not correct specs relating to temps. The best way is to bring up the live data on the screen for those 2 sensors then check the chart for reference values depending or temperature.
