asked by on May 15, 2016

my car stopped cranking over, so i went out bought a new starter, alternater, battery, and starter relay. once i replaced it all everything went together as the old parts. but when i went to go start it there was no crank. there is juice getting to all the electronics but it still wont crank. even tried jumping it from the starter with a screwdriver connecting both contact points still no crank.

My car has 100000 miles.
My car has an automatic transmission.

If you tried jumping the contacts on the starter directly, then your problem is most likely a power or ground issue. The battery ground cable may not be making a good connection at the engine ground, or there could be a problem in the positive or negative battery cables making them unable to properly complete the circuit. I would start by checking the resistance from the engine ground to the battery ground, and from starter positive to the battery positive terminal. Also do a voltage drop test across each of the cables, which will help determine if there is a problem with them. If after checking the cables and connections, the car still doesn’t start, then you should have a qualified professional, such as one from YourMechanic, diagnose the problem for you.
