On to the next project! We have a Subaru Impreza 2014 hatchback sport limited. It is slow to start after sitting for a day or 2 and what I mean is it takes longer to finally fire the engine up. Like 3-5 seconds. Internal lights don’t dim or flicker either.
I’ve replaced the battery, oil and spark plugs. I don’t think it’s the fuel pump cause I’ve tried the turn the key to the on position for a few seconds before trying to turn it over. It still happens.
The negative terminal on the battery has corrosion. I cleaned it but maybe the internal wire corroded too? I was going to try some voltage tests on the starter.
Any other thoughts or things I can give it a shot?
