Check the battery cables may be bad and you only get good power when you jump it.

Thank you, Lorne. Dealer ran same tests as before. Found loose battery cable. Lets see what happens....

Could be a fuse if you added a remote starter


My wife drives a 2003 Acura MDX. It has the same starting issues that you mentioned. Occasionally, the vehicle does nothing when the key is turned. Usually when the key is taken out and tried a few times it will eventually start. I suspected it was an ignition switch problem. Although that was not indicated on a diagnostics scan at my mechanic's garage. The only thing coming up on the scan is a Powertrain Module error. Not sure if that's it or not. Taking it to the dealership soon to have it checked out further.


In my case it was a bad battery connection. I have a 2001 Acura MDX - must say it's nice SUV. Last week I had the same problem i.e. the car won't start. The internal lights worked, horn worked, radio worked but the car won't just start and just kept making a lot of clicking sound. I tried to jump start it using a brand new jumper cable but surprisingly that failed to start the car as well. I started to wonder if my alternator/starter had gone bad. After reading a lot of forums I decided to clean the battery connections. I cleaned the terminals properly and removed the felt rings that were installed 5 months ago when I had purchased a new battery. And, the car just started with just one turn of the ignition. Obviously, the problem was with the leads where the stupid felt rings had deteriorated and accumulated gunk and that lead to a bad connection, especially on the Negative terminal. I am glad that I didn't get my car towed to the Acura dealership who were telling me that it was probably a combination of bunch of bad problems that could cost me over $500 in a series of diagnostic tests and up to $1000 in parts.
