Hi Scotty. I came across your YouTube video on car cranks but won't start. So I had a misfire code so I had the coil and sparks changed which was causing the car to shake. Now the engine stopped shaking but it doesn't start. It makes the sound of it will crank. I'm not sure if it's the starter or fuel pump. I have a Chevy Malibu 4 cylinder. My neighbor tested my battery it's find, he found nothing lose.
