I started the car and drove it in the morning started it up drove home went to use later that day and no start checked the battery and it read 9v. Replaced battery and still no start. Checked the started and its good, when key is turned to start no voltage to the solenoid wire. I'll tell you if I find out whats wrong.
Is the vehicle cranking at all? This issue may be battery related (e.g. connection issue). This is just a suggestion, not a diagnosis. I encourage you to consult with a certified technician for an official diagnosis. They will be able to offer additional information after inspecting the vehicle.
Please keep us posted. If you have additional questions, please feel free to PM me.
