My car will occasionally have issues starting when the engine is hot. At first it would only happen after a hard run on the track and I shut off my engine. More recently it has started doing this even after normal driving. When I try to restart the engine shortly after turning it off, like when pumping gas, the starter has extreme difficulty turning and won't start. If I let it cool off, the car will start again. Occasionally it'll smell like burning if I let the car try to turn over. I thought it was a battery issue since the original battery was coming up on 5 years but it still does it even with the brand new battery. Does anyone have any experience with this issue?
