When i start my car, it sounds like the battery is near dead and can barely crank over. But it starts right up with no problems. I checked the battery and it is 100% charged, all electrical connections are good. Would a blown motor or serious vacuum problem cause this? Or could it be my starter? Any input on this would be excellent. Thanks

Have you had the battery checked with a load on it? It can show full but when a load is put on it it can't sustain the output. Get it checked at a autoshop for free. Autozone comes to mind for this one.

 

That sounds like a good idea...but i can't see that being the problem. I relocated my battery about a month and a half ago and have a brand new optima. And this whole thing started last weekend. But i'll give that a try anyway.

Also, i tried compression testing my car, and it read at 65psi, on both rotors, all 4 plugs. Now i know this is f***ing horrible and its killin me that my motor is probably blown. The damn thing only has 8000 miles on it, but i'm holding onto the possibility that not having enough cranking power is what caused the low compression.

 

Oh, I also forgot to mention that if i keep cranking it, that it will eventually start to speed up and sound like its getting full power.

 

Check your starter brushes... this is exactly what happend to my car
