What to do if your starter wont spin?
What to do if your starter wont spin? Put a socket and breaker bar or wrench on the bolt at the front of the crankshaft and see if you can rotate the engine. If you can, then check all your battery cables. My guess is (because I used to do this myself) is that you removed the starter and used jumper cables to check it and not the battery cables in the vehicle. What to look for when your engine won't start? Check for a blown fuse that may be preventing a circuit from working properly, like the fuel injection...
