[James8485]

i no to check the grounds or so i ve been told had this issue alwhile back and took starter off and had it tested to find out it was perfect then when i had it in for some other stuff the mechanic said its prob a ground (tranny ground) so anyways i got it back and it was perfect again......now its starting slow again, si thought it was a battery so bought new one did the same thing so took it back and now i am lost what do i check next.... where are all the grounds i should be checking and it there a way check whats going on it just turns over slow but then fires after it turns over slow 5-6 times but when it turns fast it like half a turn! im lost and any input would be great thanks

more than likely  solenoid on the starter is about to go south ( barring a bad ground / battery conection / loose wires on the starter  )  ....

in my experience it's much easier to just  go buy a new starter , since you can change just the solenoid , but when the solenoid is bad/ going bad , the rest of the starter  will  be on it's last leg too .
