2005 Cadillac STS 6 cyl Two Wheel Drive Automatic 72000 miles
I have a 2005 Cadillac STS with 3.6L V6 and 72k miles. When brake and Start Button are pushed the dash goes black, but interior lights stay on, and will not crank/start at all(no clicking, no nothing). After 10-15 seconds, dash lights come back up as if car is running, but engine has not started. All interior lights and guages appear to be working properly. Tried jumping the car, no go. Took the battery to be tested and it tested ok but I purchased a replacement just to be sure as the dealer had replaced the battery under warrantly just 2 years before when this happened. The car still will not start. I checked the codes and only get one trouble code, U0100 "Lost communication with Engine Control Module/Powertrain control module A." I have seen several other posts on other sites regarding starting problems, but curiously, no one has posted their final resolution. Thanks.
have the same problem?
