Car shut off on way home one day and wouldn't start back. have tested crank sensors, cam sensors wiring for power and grounds module. cannot figure it out. fuel pump is working, replace fuel pump relay, ignition relay and just noticed that when key is on and if you move shifter to reverse or drive gears transmission makes a crazy buzzing sound like neutral safety switch is shorted. could this be be my problem?

Hello,

Can I ask if the engine is cranking over (starter working) or not cranking over (starter not working). Can you please shoot a quick video with your phone so we can hear the noise, that would be great. You can upload it here with your response. Here are two guides to help address both

and

Please run down these guides and report back.
