I am having trouble with my mustang. i put new heads can and intake on it and got it all put back together and now shes having a hard time turning over. its easy with the socket but the starter is having a hard time turning it over. Please help me out! thank you..

 

If what you say is true, then I would assume you forgot to reinstall the battery ground or didn't tighten it. Assuming you took it off to do the job, that is..

Otherwise it's likely an issue with the install. It shouldn't be easy to spin with a socket and ratchet, it should have compression phases and become easy or hard depending on where it is. The starter could be spinning it so fast because you lack compression that it sounds like it's barely moving.

 

its not "easy" i should have said it differently. it spins as it should with a socket and rachet. but thank you. i think one of my grounds are partially melted due to it touching the header. the previous owner didnt know what he was doing. ill replact that tomorrow and see how it goes. thank you again.

 

there fixed it for you^^^^^^^
