Thank you for telling me the location of the ECM for my 2007 Saturn Sky, you just saved me alot of time, I never noticed it was next to the water bottle all this time. My car has been having trouble starting and the battery and ignition switch are new, everyone is saying the ECM is intermitent. I even replaced the alternator a few years back. The car only has 16,000 miles but it has had some random starting issues for years and GM even put 2 batteries in it under warranty, but over the past few months it has become worse. I just ordered a new ECM yesterday. Unfortunately once I change the ECM I will need to take it to the dealer to have them flash the computer because I put on the GM turbo upgrade kit which came out in about 2009 with the new Bosch sensors, it gave me 30 extra horse power, so it was worth it. Sincerely, John Teabo
