I've been having some issues with my '05 TL not reliably starting for a while now and wanted to see if anybody else has experienced this problem. I have recently replaced the starter, battery, and neutral safety switch. About 1 out of 3 times when I try to start the car, I'll hear the click and the engine will move a little from the starter engaging but the engine doesn't start. It will usually start on the next try. Does anyone have any ideas what could be causing this?

 

Check the grounds, could be loose or just needs to be cleaned.

 

Also check the battery cables to make sure there is no corrosion and they are solid.
