2003 Pontiac grand am
No crank no start... the car is making a buzz when
I start it and that’s all. Already replaced the starter
already checked everything on the battery
countless of times ... already checked the security
system it’s off... not sure how to check for the
ignition switch which I honestly don’t think is the
problem. Also I used a test light to see if all 3 wires
was giving power to the starter and it is. Note that
I tested the ends of each wire to the starter so I
just put the test light on the nuts of the starter... I
need this car fixed what do I need to do?
