Tested it with machine it has 12 volts

I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
if it starts with a boost then the issue has to be a lack of voltage.
the three likely causes of this would be a bad/loose connection that is being compensated for when you boost, a bad battery, or a bad starter
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle
